1 00:00:02,301 --> 00:00:07,694 Through our galaxy, there is a pull Amazing gas and dust 2 00:00:07,729 --> 00:00:09,004 Seals 3 00:00:09,039 --> 00:00:13,360 Contains the secrets of the circle of cosmic life 4 00:00:13,395 --> 00:00:19,189 The birth and death of stars, planets and humans 5 00:00:19,224 --> 00:00:23,489 Those things are the cradle of creation 6 00:00:23,524 --> 00:00:29,016 You have a close relationship with the feasts You are the vows of life 7 00:00:29,051 --> 00:00:34,433 The story of our solar system begins with the nebula 8 00:00:34,468 --> 00:00:38,408 If you want to build a solar system, you will need a nebula 9 00:00:38,443 --> 00:00:43,558 Look around you, all you see Everywhere was a day inside a mist 10 00:00:44,794 --> 00:00:49,411 Scientists are now raising the curtain 11 00:00:49,446 --> 00:00:54,634 They open our eyes in front of the extension The true expanses of our universe 12 00:00:54,669 --> 00:00:59,846 They solve the mysteries of these creation engines 13 00:01:00,816 --> 00:01:04,282 There are mysteries hiding within them that we did not even imagine 14 00:01:20,131 --> 00:01:27,805 Milky Way, full spiral galaxy With areas of gas and dust called the embankments 15 00:01:27,840 --> 00:01:30,857 Everyone has their preferences 16 00:01:30,892 --> 00:01:34,360 I love the horse head nebula, looks great 17 00:01:34,395 --> 00:01:38,470 I have always been fascinated by the mist of the cat's eye 18 00:01:38,505 --> 00:01:41,887 My favorite nebula is the mighty nebula 19 00:01:41,922 --> 00:01:47,887 Maybe the mighty nebula The best place to understand the emergence of stars 20 00:01:47,922 --> 00:01:51,548 It is here in our art 21 00:01:51,583 --> 00:01:58,505 The mighty nebula is one of the most famous of the dams You can go out at night and see your eyes 22 00:01:58,540 --> 00:02:03,232 Man kept watching that patch Blurred from heaven for centuries 23 00:02:03,267 --> 00:02:09,256 The civilization of Maya in Central America is the fire of creation 24 00:02:09,291 --> 00:02:12,372 The Mayans were more right than they knew 25 00:02:12,407 --> 00:02:17,631 Almost every part can be seen from The life cycle of stars in the nebula 26 00:02:17,666 --> 00:02:21,623 We can not understand the life cycle of stars 27 00:02:21,658 --> 00:02:24,686 Without understanding the life cycle of the dams 28 00:02:24,721 --> 00:02:26,505 They are intertwined 29 00:02:27,547 --> 00:02:35,476 The mighty nebula has everything, from massive stars On the brink of death to a gas-guzzling birth star 30 00:02:35,511 --> 00:02:43,803 You can see the thin threads of materials, curtains Which enveloped the fledgling stars 31 00:02:43,838 --> 00:02:49,018 The columns hit each other and Tron Nogoma makes its way through gas withdrawal 32 00:02:49,053 --> 00:02:57,358 , You see this hive Frenetic activity, working before us 33 00:02:57,393 --> 00:03:07,374 In 2018, using new data, it is manufactured NASA envisioned a stunning outline of the depths of the mighty 34 00:03:07,409 --> 00:03:15,941 We have for the first time in history tools Fit to explore the hearts of those embellishments 35 00:03:15,976 --> 00:03:25,613 It was beautiful when starting out but we have now Clearer images to appreciate the greatness of this structure 36 00:03:25,648 --> 00:03:29,727 In the heart of the mighty are clusters of young stars 37 00:03:29,762 --> 00:03:34,630 Burst charged particles and solar wind 38 00:03:34,665 --> 00:03:40,733 To open a gap in the middle to make a window inside 39 00:03:40,768 --> 00:03:47,446 We see the structures in their origin We can see the processes happening before our eyes 40 00:03:48,355 --> 00:03:56,064 The intense starlight of the clusters activates The gas next to it is blue and blue 41 00:03:57,072 --> 00:04:00,930 The pink comes from the emitted light Of hydrogen atoms in the nebula 42 00:04:00,965 --> 00:04:03,407 Glows like gas in neon lights 43 00:04:03,442 --> 00:04:10,169 Blue comes from the light emitted by the stars New warm and reflective dust particles 44 00:04:11,068 --> 00:04:14,858 Those new hot stars illuminate the mighty nebula 45 00:04:14,893 --> 00:04:18,402 But she was born basically in the dark 46 00:04:19,214 --> 00:04:22,906 There is a distinctive type of embellishments The dark nebula is called 47 00:04:22,941 --> 00:04:27,447 It becomes so basically when Dust concentrations are larger 48 00:04:29,791 --> 00:04:35,241 Thick dust clouds are obscured The visible light of the stars behind them 49 00:04:35,276 --> 00:04:39,213 To make shaded shapes such as the horse head nebula 50 00:04:40,014 --> 00:04:46,934 This mist is very large and dense and has A mass enough to make thirty stars the size of our sun 51 00:04:46,969 --> 00:04:50,516 Astronomers can now stare inside 52 00:04:50,551 --> 00:04:53,942 We have only recently been able to start doing so 53 00:04:54,985 --> 00:04:59,636 Thanks to detectors Seeing infrared light 54 00:04:59,671 --> 00:05:06,508 Infrared light allows us to see through Dust the nebula and see what happens in the interior 55 00:05:08,341 --> 00:05:13,986 Humans can not see the light below Red but we can sensor it as heat 56 00:05:14,847 --> 00:05:23,066 The detectors tell us that dark clouds are formed The stars are hundreds of degrees Fahrenheit below zero 57 00:05:25,118 --> 00:05:28,736 But in the basement with hot basins 58 00:05:31,711 --> 00:05:33,531 If you look at infrared light 59 00:05:33,566 --> 00:05:42,588 You'll see amazing fingerprints and gradients Amazing heat, a sign that new stars are born 60 00:05:44,154 --> 00:05:48,403 Parts of the material are lumped under gravity 61 00:05:48,438 --> 00:05:51,765 When gravity increases gravity 62 00:05:51,800 --> 00:05:56,294 It attracts more gas to grow in size 63 00:05:58,455 --> 00:06:02,097 It becomes larger, denser and more hot 64 00:06:02,132 --> 00:06:05,459 Eventually the pressure and heat increase Enough at the center of this thing 65 00:06:05,494 --> 00:06:08,227 The fusion fuse ignites 66 00:06:09,017 --> 00:06:11,481 The star is born 67 00:06:15,293 --> 00:06:19,543 One hundred billion stars Which constitute our galaxy 68 00:06:20,332 --> 00:06:26,874 The latest star production lines It goes back to the dawn of time 69 00:06:26,909 --> 00:06:29,546 And to the first nebula 70 00:06:30,323 --> 00:06:35,706 If we want to reveal the history of the Milky Way We will start from the beginning, from the Big Bang 71 00:06:42,105 --> 00:06:45,418 13,8 billion years ago 72 00:06:45,453 --> 00:06:48,345 Life in the universe has died 73 00:06:49,267 --> 00:06:51,938 It was initially pure energy 74 00:06:53,334 --> 00:07:00,691 But for more than 300,000 years, that has cooled Energy to hydrogen gas and helium 75 00:07:00,726 --> 00:07:06,130 The entire universe was then one huge cloud 76 00:07:06,165 --> 00:07:16,073 The basic ingredients of our universe have spread exponentially The universe, so the universe began as a single giant 77 00:07:16,108 --> 00:07:24,279 Over time, the primitive nebula began Collapsed and splintered into small parts 78 00:07:24,314 --> 00:07:28,293 These areas have become high Density even collapsed to tablets 79 00:07:28,293 --> 00:07:32,261 The gas cylinders are very hot in their hearts 80 00:07:38,182 --> 00:07:41,070 The first stars caught 81 00:07:41,105 --> 00:07:44,239 Started with pure hydrogen 82 00:07:44,274 --> 00:07:48,793 But when you get older I made the other heavier items 83 00:07:48,828 --> 00:07:52,896 Stars are new elements, that's their function 84 00:07:52,931 --> 00:07:59,645 The definition of the star is that in its heart, it merges Hydrogen atoms to helium and releases energy 85 00:08:00,545 --> 00:08:07,891 But most of these simple first stars were Giant giant stars do not live long 86 00:08:07,892 --> 00:08:12,636 She burned all her excess Of hydrogen at super speed 87 00:08:12,671 --> 00:08:18,043 They burned themselves And died a few million years later 88 00:08:18,930 --> 00:08:21,840 She died with a bang 89 00:08:25,380 --> 00:08:31,878 Explosion issued more elements Complicated to the initial nebula 90 00:08:33,153 --> 00:08:36,473 After the formation of the first generation of stars 91 00:08:36,508 --> 00:08:39,542 There was a huge resurgence of new elements 92 00:08:39,577 --> 00:08:42,112 Which formed and spread across the universe 93 00:08:42,147 --> 00:08:45,604 To be able to form the second generation of stars 94 00:08:45,639 --> 00:08:49,509 When the second generation of stars lived and died 95 00:08:49,544 --> 00:08:53,497 It added more components to the cosmic mix 96 00:08:53,532 --> 00:08:57,741 The next generation of stars Merge more elements and explode and die 97 00:08:57,776 --> 00:09:02,912 Its elements are being disseminated to the new generation of The embellishments to be the new generation of stars 98 00:09:02,947 --> 00:09:10,358 Each generation has more elements In the periodic table of its predecessor 99 00:09:12,576 --> 00:09:21,440 After the Big Bang 300 million General Our Milky Way galaxy was formed 100 00:09:21,475 --> 00:09:26,189 Galaxies formed like the Milky Way From the initial Hungarian nebula 101 00:09:26,224 --> 00:09:31,354 A giant gas cloud collapsed and formed our galaxy 102 00:09:32,834 --> 00:09:36,705 There is a rich cosmic music 103 00:09:36,740 --> 00:09:40,111 Play between stars and endings 104 00:09:40,146 --> 00:09:45,411 We now know that we are part of that grandeur 105 00:09:49,243 --> 00:09:54,228 In the end our sun was born rich in elements 106 00:09:56,315 --> 00:10:00,075 We believe that our sun is a third-generation star 107 00:10:00,110 --> 00:10:06,697 There was a mist then a star A nebula, then a nebula, and our sun 108 00:10:07,691 --> 00:10:16,631 It took ten billion years to form a mix Cosmic elements rich enough to form planets of life 109 00:10:16,666 --> 00:10:21,628 Carbon, hydrogen and nitrogen Oxygen, phosphorus and sulfur 110 00:10:21,663 --> 00:10:25,788 These are the main elements of life as we understand them 111 00:10:25,823 --> 00:10:28,967 It must be formed within the stars 112 00:10:29,002 --> 00:10:32,206 These elements formed during the life of the star 113 00:10:32,241 --> 00:10:38,704 But it needs a very violent process to liberate it to the universe 114 00:10:40,100 --> 00:10:48,604 An event that can be clearly seen across The Universe 115 00:11:03,900 --> 00:11:09,479 The most beautiful embellishments in our galaxy consist Of extreme violence 116 00:11:09,514 --> 00:11:12,329 Death of massive stars 117 00:11:13,822 --> 00:11:18,487 One of the most beautiful colorful embellishments in our galaxy They are the remnants of the great explosions 118 00:11:18,920 --> 00:11:23,156 Such as the cancer nebula, the A-chair, and the veil 119 00:11:23,191 --> 00:11:27,403 All formed when a huge star exploded violently 120 00:11:30,835 --> 00:11:38,281 The nebula was a star About ten times the mass of the sun 121 00:11:42,734 --> 00:11:49,441 This star will crush him The atoms together form heavier elements 122 00:11:49,476 --> 00:11:53,565 The process produces huge amounts of energy 123 00:11:54,378 --> 00:11:58,780 The big star can To incorporate heavier and heavier elements 124 00:11:58,815 --> 00:12:05,452 , Until it reaches the iron Then things get worse 125 00:12:05,487 --> 00:12:12,839 Iron atoms are so large that Incorporating it needs more energy than it produces 126 00:12:12,874 --> 00:12:19,813 The pulp begins to collapse on Himself to trigger a catastrophic explosion 127 00:12:23,440 --> 00:12:28,147 He explodes the elements into space 128 00:12:28,898 --> 00:12:32,562 When the star turns to a low The greatest it tear itself violently 129 00:12:32,597 --> 00:12:35,800 And all elements of the star To spread for light years 130 00:12:36,988 --> 00:12:41,755 We call it the nebula of the supernova 131 00:12:41,790 --> 00:12:44,897 We now have a nebula full of all Those exciting chemicals 132 00:12:44,932 --> 00:12:50,064 All of them are lit by the explosion of the supernova 133 00:12:50,888 --> 00:12:56,177 The remnants of the supernova Glowing glow in different colors 134 00:12:56,917 --> 00:13:04,766 The colors are represented in the mist or fingerprint Test the DNA of the elements inside it 135 00:13:05,605 --> 00:13:10,369 Each atom has a cloud cover of The electrons that orbit their nuclei 136 00:13:10,404 --> 00:13:16,341 When electrons change energy levels, The frequency of light associated with that variable energy 137 00:13:16,376 --> 00:13:23,317 Send to space and contribute to The wide spectrum of colors we see 138 00:13:23,352 --> 00:13:29,977 We can look at distant plugins and say that They have lots of hydrogen or helium 139 00:13:29,977 --> 00:13:35,122 Or a little platinum or a lot of oxygen 140 00:13:36,649 --> 00:13:42,850 Colors reveal the elements Made during the life of the star and his death 141 00:13:44,714 --> 00:13:50,416 But the shape of the mist reveals What happens after the death of the star 142 00:13:50,451 --> 00:13:55,671 You may think that the explosive star has Similar to others with the same type of mist 143 00:13:55,706 --> 00:14:00,054 Then you see the crab nebula in its beautiful complex form 144 00:14:00,089 --> 00:14:03,396 All of those brackets Swirls of gas and dust 145 00:14:03,431 --> 00:14:07,282 Something must be inside 146 00:14:08,451 --> 00:14:14,932 Disappears inside the nebula of cancer An astral body is called a pulsating star 147 00:14:14,967 --> 00:14:17,791 Stars are a kind of neutron star 148 00:14:17,826 --> 00:14:19,996 A ball of high density material 149 00:14:20,031 --> 00:14:24,819 Born from the death of giant stars 150 00:14:24,854 --> 00:14:27,835 It is the remains of the core of an explosive star 151 00:14:27,870 --> 00:14:33,092 He collapsed and formed a small ball of Nitrons are a small part of normal matter 152 00:14:33,127 --> 00:14:37,696 She is very hot and she has Strong magnetic field 153 00:14:39,092 --> 00:14:43,308 This pulse is about thirty times a second 154 00:14:44,968 --> 00:14:52,614 To detonate radiation spread in Space as a raging cosmic lighthouse 155 00:14:52,649 --> 00:15:02,502 Pulses in the nebula do not release light But rather releases winds from charged particles 156 00:15:02,537 --> 00:15:06,041 The cloud of gas around it is the nebula of the winds of spring 157 00:15:06,076 --> 00:15:13,433 So take all remaining materials from the potter The greatest and launched in that extended cloud 158 00:15:13,468 --> 00:15:21,492 The winds of springing through the gas Ocean to make swirls and the nebulae of the crab nebula 159 00:15:27,429 --> 00:15:29,962 The supernovae create the elements 160 00:15:32,496 --> 00:15:36,119 Spread by the winds through the universe 161 00:15:36,955 --> 00:15:39,538 To be new dams 162 00:15:40,397 --> 00:15:45,233 Socks may be a solar system like our system 163 00:15:46,918 --> 00:15:52,606 Nebula starting point of the solar system configuration 164 00:15:52,641 --> 00:15:59,937 All ingredients, chemicals and gases And solids that we see in our solar system today 165 00:15:59,972 --> 00:16:03,172 Imagine the main elements Which is the planet 166 00:16:03,207 --> 00:16:06,154 What happened to bring them together? 167 00:16:06,189 --> 00:16:11,668 How to cloud a gaseous element To become our planets and sun? 168 00:16:11,703 --> 00:16:16,321 What about the nebula to our solar system? 169 00:16:33,711 --> 00:16:40,472 In the past they were not there Sun or solar system or human 170 00:16:40,507 --> 00:16:47,226 Just a cloud of gas The dust is a solar nebula 171 00:16:47,261 --> 00:16:56,295 We are here today because it is billions of years ago There was a nebula with all the necessary ingredients 172 00:16:56,330 --> 00:17:06,856 Everything we see in our solar system today was a part From a cloud of gas and dust, our solar nebula 173 00:17:07,669 --> 00:17:14,229 Five billion years ago are being processed The solar nebula to be our sun 174 00:17:14,264 --> 00:17:19,613 So billions of years ago there was Our solar nebula is a cloud of gas and dust 175 00:17:19,648 --> 00:17:22,279 It was outstanding but unstable 176 00:17:22,314 --> 00:17:28,002 What upset the balance to turn Cloud gas to solid particles? 177 00:17:28,037 --> 00:17:33,980 , Something must change inside the nebula Something that raises stars and planets 178 00:17:34,015 --> 00:17:35,897 This remains a mystery 179 00:17:35,932 --> 00:17:41,340 What is the answer to this five-billion-year-old puzzle? 180 00:17:47,440 --> 00:17:54,195 There are two theories, both of which begin with fossils 181 00:17:54,230 --> 00:17:59,833 Fossils made their way from The edge of the solar system towards Earth 182 00:17:59,868 --> 00:18:05,981 Our air cover broke through and made its way towards us 183 00:18:08,987 --> 00:18:12,573 Meteorites are important for us to understand and study 184 00:18:12,608 --> 00:18:18,601 Because it capsules time to when The solar system was basically composed 185 00:18:19,692 --> 00:18:26,006 Mina and Adwa are one of the biggest Compounds of comets on Earth 186 00:18:26,041 --> 00:18:32,774 Those rocks have pure records For the early history of the solar system 187 00:18:32,809 --> 00:18:38,352 There was not in the solar system Something before the origin of those rocks 188 00:18:38,387 --> 00:18:42,598 There was no land or other planets, this is amazing 189 00:18:42,633 --> 00:18:48,850 The first solid objects that originated from Cloud dust surrounding our newborn star 190 00:18:48,885 --> 00:18:56,697 Contained the asteroids and meteorites that formed at that time Time on chemical fingerprints of our solar nebula 191 00:18:56,732 --> 00:19:05,880 It contained the oldest elements and solids that condensed From the cloud of gas and dust when our solar system was formed 192 00:19:05,915 --> 00:19:11,459 I fought together and formed these The big rock you see here 193 00:19:11,494 --> 00:19:17,192 In 2017, researchers who analyze Configure a type of solid meteorites 194 00:19:17,192 --> 00:19:23,583 Called Kondrit, they found evidence About how to configure our solar system 195 00:19:23,618 --> 00:19:28,027 There may be some hard evidence somewhere Within the chemical composition of those rocks 196 00:19:28,027 --> 00:19:33,923 He tells us exactly what happened And how our solar system originated 197 00:19:34,034 --> 00:19:39,337 This definitive guide is A radioactive component called iron-60 198 00:19:39,372 --> 00:19:44,880 It is believed to be only In the Great Revolutions 199 00:19:46,503 --> 00:19:50,147 If there was a nebula ready to form stars 200 00:19:50,182 --> 00:19:52,354 And next to him came a greater calamity 201 00:19:52,389 --> 00:19:56,312 The great hypocrite will throw all these Heavy elements of the gas cloud 202 00:19:56,347 --> 00:20:03,215 It will also research the composition of stars By hitting and compressing this gas 203 00:20:04,606 --> 00:20:07,409 A nearby star explodes into a larger one 204 00:20:07,444 --> 00:20:14,181 The shock wave hits our bosom Solar system for iron 205 00:20:16,633 --> 00:20:23,841 But the crash is a breakdown A sudden attraction at the core of the mist 206 00:20:23,876 --> 00:20:28,283 The gas cloud is clogged Together to become hot and dense 207 00:20:28,318 --> 00:20:31,389 And our sun is born 208 00:20:32,155 --> 00:20:37,100 When the sun arose, there were A cloud of snakes around the sun 209 00:20:37,135 --> 00:20:44,283 When it was circling the sun, it merged And clung to each other and grew into those balls 210 00:20:45,231 --> 00:20:54,780 Over the next hundred million years, those balls became Larger and larger to be asteroids, moons and planets 211 00:20:56,130 --> 00:20:59,708 All the planets in our solar system look different 212 00:20:59,743 --> 00:21:03,689 Some are snow giants and others Gaseous giants and some rocky bodies 213 00:21:03,724 --> 00:21:09,903 But all came in fact From the same nebula before the sun 214 00:21:09,938 --> 00:21:17,864 Our planet grew up With the right combination of elements 215 00:21:18,823 --> 00:21:25,339 Everything, every atom in our bodies She was formerly Sodema before my sun 216 00:21:26,747 --> 00:21:33,254 The theory of the Great Surgeon By pushing our strong solar system configuration 217 00:21:33,289 --> 00:21:35,328 But not everyone agrees 218 00:21:35,363 --> 00:21:40,234 Sometimes the biggest arguments come Among the scientists of the smallest things 219 00:21:40,269 --> 00:21:45,330 Here I speak of small radioactive atoms 220 00:21:46,156 --> 00:21:53,997 In 2017, studies showed containment Other meteorites have other radioactive imprints 221 00:21:54,032 --> 00:22:00,074 Rare aluminum alloy The so-called aluminum-26 222 00:22:00,109 --> 00:22:04,042 It is an irregular atom that does not form Easily in great twists 223 00:22:04,077 --> 00:22:07,148 It must have come from somewhere else 224 00:22:08,048 --> 00:22:16,224 This other place is a rare type of star Giant by forty to fifty times the mass of our sun 225 00:22:16,259 --> 00:22:19,173 Star Wolf Wright 226 00:22:19,962 --> 00:22:25,423 , The stars may be strange The largest is very strange 227 00:22:25,458 --> 00:22:31,708 The largest kind of stars that We saw her as the stars of Wolf Ray 228 00:22:32,472 --> 00:22:41,136 The stars of Wolf Rye burn more powerful than any star to produce Heavy elements such as aluminum-26 during their short lives 229 00:22:41,171 --> 00:22:43,880 It is huge, hot and shiny 230 00:22:43,915 --> 00:22:46,888 It unleashes tremendous winds 231 00:22:46,923 --> 00:22:53,621 These stellar winds release tons of energy Materials from the star to the ocean space 232 00:22:53,656 --> 00:22:56,693 To form a bubble structure 233 00:22:57,614 --> 00:23:04,750 Scientists see the process in the nebula The bubble is 7,000 light years away from Earth 234 00:23:05,489 --> 00:23:10,651 In the middle of the mist there is one Massive stars with enormous starry winds 235 00:23:10,686 --> 00:23:18,514 High-energy particles, radiation, as the name suggests It releases a bubble in the huge mist around it 236 00:23:18,522 --> 00:23:23,667 The walls or bubble crust are dense and full of materials 237 00:23:23,702 --> 00:23:28,580 Stellar winds drive more The more material inside the cortex 238 00:23:30,037 --> 00:23:37,854 So that the substance collapses with an effect Its attractiveness and condensation into stars 239 00:23:37,889 --> 00:23:44,770 Possibly what we see in the bubble nebula Is what happened here 4,5 billion years ago 240 00:23:44,805 --> 00:23:47,829 To form the sun and the planets 241 00:23:47,864 --> 00:23:52,927 If our solar system grew up Inside Bubble Nebula Wolf Ra> 00: 242 00:23:52,962 --> 00:23:59,127 This will explain the abundance of aluminum-26 Located in meteorites 243 00:24:00,585 --> 00:24:03,049 But it was not decided 244 00:24:05,184 --> 00:24:11,373 What we know is that our story has begun The collapse of the solar nebula 245 00:24:12,187 --> 00:24:16,275 But our star will someday die 246 00:24:16,956 --> 00:24:24,383 Does the sun turn into a mist? Awesome or darkened dim? 247 00:24:40,330 --> 00:24:43,608 The embellishments will be stars 248 00:24:45,745 --> 00:24:48,900 The stars are the embellishments 249 00:24:48,935 --> 00:24:54,193 The largest stars do so With violent superpowers 250 00:24:55,685 --> 00:25:01,766 But 99% of the stars are not Big enough to die exploding 251 00:25:02,554 --> 00:25:07,009 Some burn themselves to death 252 00:25:08,490 --> 00:25:16,765 But other stars can be dams Beautiful as a misleading ,, Planetary Safes 253 00:25:16,800 --> 00:25:24,399 From afar they look like planets but ghosts of stars 254 00:25:24,434 --> 00:25:30,856 When stars like our sun begin to die, Swells to what we call red giant stars 255 00:25:31,658 --> 00:25:38,611 When the stars reach the size of the sun At the end of her life, her heart is getting hotter and hotter 256 00:25:38,646 --> 00:25:46,196 When the heat is hot, the gas expands Ocean to turn the star into a red giant 257 00:25:49,594 --> 00:25:55,444 It becomes so large that it is no longer stuck Gravity with its outer layers 258 00:25:56,233 --> 00:26:01,756 The outer layers of that star begin to drift Away to lose contact with the central core in the middle 259 00:26:01,791 --> 00:26:06,610 And begin to explode into scales and colors and beautiful forms 260 00:26:06,645 --> 00:26:09,726 We call those starving stars with Planetary Feasts 261 00:26:09,761 --> 00:26:14,594 We discovered about three Thousands of planetary nebulae in our galaxy 262 00:26:14,629 --> 00:26:22,386 Some seem like hourglasses and others Like a clown or clown or ball or cake 263 00:26:22,421 --> 00:26:28,770 But if they were all ghosts of the same kind So why this great contrast? 264 00:26:28,805 --> 00:26:32,155 If there was a star alone Without planets and without anything around it 265 00:26:32,190 --> 00:26:34,655 It will blow its winds in a spherical crust 266 00:26:34,690 --> 00:26:39,765 If you see Sodema like this It would look like a bubble of soap in space 267 00:26:39,800 --> 00:26:46,658 But only 20% of the embellishments Planetary form of a bubble full of consistency 268 00:26:46,693 --> 00:26:53,842 Most of them have these exotic forms They look like two-lobe or two opposite squid 269 00:26:53,877 --> 00:26:57,446 All shapes are different 270 00:26:59,133 --> 00:27:06,950 Experts believe that alien forms to those Planetary masts may relate to how the star dies 271 00:27:08,564 --> 00:27:13,553 A new research shows the fate of our star 272 00:27:16,306 --> 00:27:20,685 Sadema will be a bright planet Beautiful or just disappear in the dark? 273 00:27:20,720 --> 00:27:25,042 We believe for the first time that we have the answer 274 00:27:26,657 --> 00:27:32,428 It's a long-standing debate, is it our sun? Big enough to be an amazing sdema? 275 00:27:32,463 --> 00:27:37,631 It is a strange coincidence that the model appears We need a specific mass to form a planetary nebula 276 00:27:37,666 --> 00:27:42,385 By chance, the sun is too high 277 00:27:44,641 --> 00:27:49,044 Assume new data That our sun will die dazzled 278 00:27:51,312 --> 00:27:57,999 When the sun dies, it will expand To a red giant filling the sky 279 00:27:58,837 --> 00:28:02,252 We got used to our yellow sun Kind of moving in sight 280 00:28:02,287 --> 00:28:09,517 Imagine a shiny red glowing ball A huge swell across the horizon instead of the sunrise 281 00:28:11,687 --> 00:28:18,405 The expanding sun swallows Mercury and then Venus 282 00:28:19,376 --> 00:28:22,215 The surface of the earth will be roasted 283 00:28:22,250 --> 00:28:25,961 To turn him into an infamous hell 284 00:28:26,774 --> 00:28:30,740 The bad news is that when The sun expands like a red giant 285 00:28:30,775 --> 00:28:36,258 , They will capture the Earth's oceans Life will not endure then on Earth 286 00:28:36,293 --> 00:28:38,162 Like putting your head in the oven and kneading it 287 00:28:38,197 --> 00:28:40,271 It will be a hard time on earth 288 00:28:42,854 --> 00:28:47,510 This may mean the destruction of the planet 289 00:28:47,545 --> 00:28:51,937 We think the sun will grow To swallow the earth's position now 290 00:28:51,972 --> 00:28:58,206 Instead of sunrise and sunset We will find ourselves inside the sun 291 00:29:03,385 --> 00:29:08,769 The sun will expose its outer layers To throw more than half of its mass 292 00:29:09,933 --> 00:29:13,027 To reveal the stellar pulp 293 00:29:13,062 --> 00:29:19,200 When we look at this pulp is called Then the white dwarf was the size of the earth 294 00:29:19,235 --> 00:29:24,159 It will be very hot, hundreds of thousands of degrees 295 00:29:25,020 --> 00:29:29,703 This white core radiates hot Ultraviolet light and x-ray 296 00:29:32,191 --> 00:29:38,584 They are impacted by external gas layers And turning them into ultra-gloss rings 297 00:29:39,470 --> 00:29:44,736 A planetary nebula will last 10,000 years 298 00:29:44,771 --> 00:29:48,886 It is certain that when the sun turns into a planetary nebula 299 00:29:48,886 --> 00:29:54,422 The solar system will look very different What it is today, will become unfamiliar 300 00:29:55,276 --> 00:30:00,396 The planetary nebula would mean an end The solar system we know 301 00:30:01,173 --> 00:30:05,139 The sun will eventually die And dissolve into space again 302 00:30:05,174 --> 00:30:07,374 But then the cycle will begin again 303 00:30:07,409 --> 00:30:11,438 It is not just an end, it is also a beginning 304 00:30:12,240 --> 00:30:19,190 The plug-in will be supplied Will create a new solar system 305 00:30:19,870 --> 00:30:27,851 When a solar system dies it is born Another, this cosmic life cycle 306 00:30:27,886 --> 00:30:32,836 The signs always signify change in the universe 307 00:30:32,871 --> 00:30:37,991 Strongly related to the star's birth and death 308 00:30:38,026 --> 00:30:45,513 Some new notes appear Our favorite soups are dying too 309 00:30:45,548 --> 00:30:50,377 Can be columns Famous creation dead already? 310 00:31:10,119 --> 00:31:17,411 Inside the depths of Eagle Eagle Nebula Dense of cool molecular gas 311 00:31:17,446 --> 00:31:23,719 Probably the best known images In astronomy, pillars of creation 312 00:31:23,754 --> 00:31:27,274 One of the defining images is the pillars of creation 313 00:31:27,309 --> 00:31:33,315 They were pictures that arouse my memory and my emotion 314 00:31:34,151 --> 00:31:36,869 The columns are five light-years wide 315 00:31:36,904 --> 00:31:41,420 They are shaded by nearby star cluster lights 316 00:31:41,455 --> 00:31:46,491 And those stars have not carved the shape of columns 317 00:31:47,934 --> 00:31:55,385 The surfaces of those stars are full of activity Boiling and constantly releasing particles 318 00:31:55,420 --> 00:32:01,463 Stellar winds at ten thousand miles At the hour you get caught up in the ocean gas pull 319 00:32:01,498 --> 00:32:07,842 In the end, the surrounding mist dissipates 320 00:32:07,877 --> 00:32:14,163 When the mist disappears, you will live Pull thicker and denser 321 00:32:14,975 --> 00:32:16,299 But how long? 322 00:32:17,075 --> 00:32:21,334 "When you look at the pictures" Hubble Beautiful pillars of creation, eagle eagle 323 00:32:21,369 --> 00:32:25,773 You see a scattered blue gas Around the columns themselves 324 00:32:25,808 --> 00:32:30,687 This is a guide on how to configure columns And how it will change over time 325 00:32:31,464 --> 00:32:38,634 This blue foggy gas is just a substance The superheavy evaporates from the same columns 326 00:32:38,669 --> 00:32:42,858 Nearby stars are slowly melting the columns 327 00:32:43,826 --> 00:32:48,400 This is similar to the way it occurs Factors of erosion here on Earth 328 00:32:49,164 --> 00:32:56,481 Look at the Monemeunt Valley and those rocky columns Stunning and exotic forms emanating from the earth 329 00:32:56,516 --> 00:33:01,381 These areas are denser than rocks They were covered by soil and sand 330 00:33:01,416 --> 00:33:07,835 For millions of years, those substances have been crushed The lighter to reveal the thickest rocks beneath it 331 00:33:07,870 --> 00:33:10,846 That's exactly what happened here 332 00:33:13,224 --> 00:33:15,492 That process is under way 333 00:33:15,527 --> 00:33:19,483 The pillars are constantly evolving 334 00:33:19,518 --> 00:33:25,343 Know that the pillars of creation A temporary feature in the life of the galaxy 335 00:33:25,378 --> 00:33:27,029 It will not last forever 336 00:33:27,064 --> 00:33:33,936 In fact, over the time since the capture Hubble Space Telescope Photo We've seen a change 337 00:33:35,452 --> 00:33:41,457 When astronomers compared data New "Hubble" images since 1995 338 00:33:41,492 --> 00:33:48,954 They discovered an exploding crater from the mist At a speed of 450 thousand miles per hour 339 00:33:48,989 --> 00:33:53,941 Stretching a hundred billion miles into space 340 00:33:54,875 --> 00:33:59,000 What might be the source of all that energy? 341 00:33:59,035 --> 00:34:03,160 These are associated with the birth of a star 342 00:34:03,195 --> 00:34:11,388 Stars born inside columns make their way Outside, eat that substance and blow it away 343 00:34:12,211 --> 00:34:16,240 The nascent stars like children flock to candy 344 00:34:16,275 --> 00:34:20,438 Eat up gas then spin out of control 345 00:34:20,473 --> 00:34:23,627 But the stars also have a magnetic field 346 00:34:23,805 --> 00:34:26,488 This magnetic field spins quickly 347 00:34:26,523 --> 00:34:34,126 The material is swept around it and released To the outside through the plumes of the poles of the star 348 00:34:34,161 --> 00:34:40,532 They are emitters and astral winds Destroying the columns of creation from the inside out 349 00:34:43,565 --> 00:34:52,556 Even worse, these nascent stars grow Quickly until you soon reach the end of her violent life 350 00:34:54,001 --> 00:35:01,027 When the stars die they send waves Shock, high-energy radiation, particles 351 00:35:04,292 --> 00:35:08,819 Great blasts explosions As such, the columns may be torn completely 352 00:35:12,131 --> 00:35:19,486 Some assume that those columns may Already destroyed thousands of years ago 353 00:35:21,051 --> 00:35:29,265 The Eagle Nebula is seven thousand years old So we see it as it was seven thousand years ago 354 00:35:29,300 --> 00:35:31,536 Not as it is now 355 00:35:31,571 --> 00:35:34,788 It is the sad reality of life 356 00:35:34,823 --> 00:35:38,452 The stars that you make are destroyed 357 00:35:38,487 --> 00:35:45,176 , This happens all the time, everything changes Our favorite famous sodas will not last forever 358 00:35:45,211 --> 00:35:50,553 It seems sad, but so does the universe 359 00:35:50,588 --> 00:35:55,284 It's a temporary situation, it's change 360 00:35:55,319 --> 00:36:02,685 We see the pillars of creation today and will be Future clusters of stars 361 00:36:02,720 --> 00:36:09,723 But this is the continuous rotation of the gas Dust to the stars will not last forever 362 00:36:09,758 --> 00:36:14,165 The embellishments across the universe disappear 363 00:36:15,609 --> 00:36:19,395 Is gas out of our galaxy? 364 00:36:39,113 --> 00:36:47,031 A new search appears to be across the universe The star formation rate falls quickly 365 00:36:47,066 --> 00:36:55,466 Researchers predict that 95% of all The stars that will exist have already arisen 366 00:36:55,501 --> 00:36:59,751 Until the galaxy is intact And maintain the star formation 367 00:36:59,751 --> 00:37:05,501 It needs to collect reserves New constantly ,, Stuff 368 00:37:05,501 --> 00:37:16,158 Gas runs out of our galaxy and so on I speak with galaxies all over the universe 369 00:37:17,638 --> 00:37:21,979 That cycle will slow down and will one day stop 370 00:37:24,831 --> 00:37:31,421 More gas is trapped in the small stars The mass that will not explode in a greater velocity 371 00:37:32,233 --> 00:37:38,568 And the big stars that An explosive die pays gas away 372 00:37:38,603 --> 00:37:40,787 The galaxies throw materials 373 00:37:40,787 --> 00:37:49,711 Great wind turbines and lighters are sent Continuously streams of gas and particles outside the galaxy 374 00:37:49,746 --> 00:37:56,345 But the stars do not work alone But cooperate with something bigger 375 00:37:56,380 --> 00:38:05,251 Experts believe that the main culprit falls At the center of each galaxy ,, The super black hole 376 00:38:06,199 --> 00:38:10,701 In the past, the Milky Way measured the loss of gas 377 00:38:11,479 --> 00:38:18,091 Hundreds of millions of years ago, it was a black hole The central is super-large and charges some materials 378 00:38:18,126 --> 00:38:24,317 In that process he launched many Energy, like a lot of energy belching 379 00:38:24,352 --> 00:38:28,941 He fired gas and probably escaped some It is completely out of the galaxy 380 00:38:31,961 --> 00:38:36,465 Our galaxy today is still the star 381 00:38:39,510 --> 00:38:42,823 But the gas tank needs to be refilled 382 00:38:43,587 --> 00:38:48,490 The galaxies spin with nitrogen Be the pillars and the stars 383 00:38:48,525 --> 00:38:51,827 It seems we have now come to a refilling station 384 00:38:51,862 --> 00:38:57,785 We discovered a huge cloud space Of hydrogen heading towards us 385 00:38:57,820 --> 00:39:02,312 That cloud of hydrogen is huge 386 00:39:02,347 --> 00:39:07,106 With a length of ten thousand light years and a width of three thousand 387 00:39:07,141 --> 00:39:10,698 "Cloud scientists call it" Smith 388 00:39:10,733 --> 00:39:18,961 It revolves around our galaxy and hate 27 Million years will hit the disk of our galaxy 389 00:39:18,996 --> 00:39:22,895 Will bring about the vital collision of our galaxy 390 00:39:22,930 --> 00:39:25,526 To reshape the stars strongly 391 00:39:25,561 --> 00:39:30,164 There will be plenty of gas Million times the mass of the sun 392 00:39:30,199 --> 00:39:32,786 He can form one million suns 393 00:39:32,821 --> 00:39:36,413 But this is just a snack 394 00:39:36,448 --> 00:39:41,315 To maintain star formation You need a galaxy for continuous food 395 00:39:41,350 --> 00:39:44,774 , Here in the Milky Way galaxy We are still stars 396 00:39:44,809 --> 00:39:48,257 This is because our galaxy is galactic 397 00:39:48,292 --> 00:39:54,118 It is surrounded by dwarf galaxies And eat it and steal its gas and dust 398 00:39:54,153 --> 00:40:00,140 We are the product of mergers, merging Many small galaxies collide 399 00:40:00,175 --> 00:40:02,376 When a new galaxy hits the Milky Way 400 00:40:02,376 --> 00:40:08,595 They bring with it gas and dust New and the possibility of creating new dams 401 00:40:08,999 --> 00:40:17,945 By eating a variety of foods add the Milky Way A few billion years of star formation 402 00:40:18,597 --> 00:40:22,748 But our galaxy is always looking for its next meal 403 00:40:22,783 --> 00:40:30,283 Within a few billion years Her neighbor will be struck by the galaxy of serial women 404 00:40:30,318 --> 00:40:37,963 When the women merge with the trail Tebbana will provide us with a new quantity of gas 405 00:40:37,998 --> 00:40:43,627 Although this is a tragic accident It is really a good thing 406 00:40:43,662 --> 00:40:47,950 Because when it happens stars will be born New inside the Milky Way 407 00:40:47,985 --> 00:40:52,206 This will prolong the life of our galaxy if we thought so 408 00:40:52,241 --> 00:40:57,190 But there are few galaxies Nearby to eat Milky Way 409 00:40:57,225 --> 00:41:01,000 In the end on the run Long will run out of nebula gas 410 00:41:01,035 --> 00:41:04,923 When this gas runs out, there will be no new stars 411 00:41:04,958 --> 00:41:10,869 Whatever happens then it will be Those are the last generations of stars 412 00:41:11,778 --> 00:41:18,342 Without gas to feed, the dams will disappear across the universe 413 00:41:19,275 --> 00:41:22,017 The universe stops 414 00:41:22,052 --> 00:41:25,973 The dams run out and disappear 415 00:41:26,008 --> 00:41:30,851 The last stars will eventually be turned off 416 00:41:30,886 --> 00:41:35,047 From now on, everything will be dark 417 00:41:35,082 --> 00:41:41,844 The dams ,, One of the finest features of the universe 418 00:41:41,879 --> 00:41:48,769 What makes the babe embellishments it Pretty but more 419 00:41:48,804 --> 00:41:51,547 It is the cradle of creation 420 00:41:51,582 --> 00:41:57,588 The start and end stars Building upon them planets and life 421 00:41:57,623 --> 00:42:01,138 I think it's amazing to learn about the universe 422 00:42:01,173 --> 00:42:05,044 I think we finally learn about ourselves 423 00:42:05,079 --> 00:42:10,309 It is our instrument of communication with the circle of cosmic life 424 00:42:10,344 --> 00:42:14,823 The parallels match our lives 425 00:42:14,858 --> 00:42:16,752 , It is very beautiful 426 00:42:16,753 --> 00:42:19,177 But it is temporary 427 00:42:19,212 --> 00:42:20,974 It will not last here forever 428 00:42:21,009 --> 00:42:23,278 This is the story of our universe 429 00:42:23,313 --> 00:42:25,085 This is the story of change 430 00:42:25,120 --> 00:42:28,979 So take your day
