It's big enough to detect very faint radio emissions from the black hole in our own galaxy, 25,000 light-years away. The superdense core is now a neutron star. On the other side of a black hole, there could even be a Big ***. _________ parts of nebulas contain the most matter. When giant loops collide on the surface of a star, the energy released sends temperatures soaring from 5. Trillions of years from now, it'll all be used up. There's a corpse a corpse of a supernova explosion. That extreme heat triggers the solar wind, sending millions of tons of particles streaming out into space. It's nearly a million kilometers in diameter, yet our sun is tiny compared to the really big stars out there. They changed the Universe by generating new generations of stars, then planets and finally the bricks of life. These appearances indicate the fact that the universe is represented in everyone of its particles. Calculate the temperature of 2.50 g CO2gas occupies 5.60 liters at 789 torr inoC. It's more than a billion kilometers across. 6. This would not be a safe place to be when the laser was fired. We really just don't know what happens at the center of a black hole. May 10, 2010. How the universe works - Answer Key Star dust is the building blocks of life. There's only so much hydrogen in the universe. Alien Solar Systems 8. The center of the galaxy is a very extreme environment. The secret of the stars is Einstein's equation e=mc2. 3.if our sun was the size of betelgeuse it would reach out as far as the planet ______________, 5._____________ of new stars are born from one nebula, 6._____________ parts of nebulas contain the most matter, 7.in 2004 the spitzer telescope was launched. Here in this lab in Rochester, New York, scientists are making a supernova with a giant laser. Every star will eventually die because its fuel runs out. Stars produce massive amounts of heat and light over billions of years. At the center of the new galaxy is a young, supermassive black hole feeding on the gas, getting bigger and bigger. It's made up of billions of stars, including our sun all revolving around a mysterious region right at the center. It's blasted into space in huge jets of energy. 20. gases in the sun will expand and it will turn into a _____________ _______________. Displaying . In 2004, NASA launched the Swift probe to scan the universe for gamma-ray bursts. If a black hole approached Earth, all that gravity would rip asteroids from their orbits and hurl them toward our planet. We're able to re-create the conditions within a star. Worlds That Never Were (aka Asteroids), 2. Albert Einsteins theories proved that stars tap into the energy of atoms. The Universe 7 Seasons 62 Episodes about Episodes About the Show From the planets to the stars and out to the edge of the unknown, history and science collide in THE UNIVERSE. The Immortal Life of Henrietta Lacks. 22. They're the same size as our entire solar system. 42min. The hit sci-fi horror will take on a new life as a stage play, "Stranger Things: The First Shadow," Netflix announced on Wednesday. The way black holes are really devastating is because when you get close to them, the gravity gets super-strong. But the Milky Way isn't the only galaxy with a black hole in the middle. But even after the universe's most violent explosion, there's something left behind. The kayaker can paddle against it and get away. _____ 1. Black holes are on the loose right here in our own cosmic neighborhood. To smash hydrogen atoms together, the tokamak heats them to more than 166 million degrees. b) Calculate the wavelength (in nm). And there are magnetic forces and frictional forces, and it's just a witch's brew, a nightmare, what's going on right above the surface of the black hole. Calculate the pH of a solution of 0.157 M pyridine. But some stars are even bigger than that. Why dont stars blow apart? Giant crystals of pure carbon are at the center of a white dwarf. High above the clouds on Mauna Kea, in Hawaii, the giant Keck telescope has the power to see right through to the center of the Milky Way. The tale of Henrietta Lacks (or rather, of her now-immortal cells) is not only a fascinating scientific story, but also a disturbing account of exploitation and injustice in the American research system. Back then, the universe was filled with clouds of gas from the Big ***. The iron killed a star in just a few seconds dangerous stuff. It keeps going and crosses the event horizon. It's a good question. New elements are blasted far into space. As the Keck kicks into action, a laser beam detects tiny disturbances in the atmosphere that would distort the image. These supermassive stars weigh and have 100 times more gravity. Well, we still have stars illuminating the sky, stars creating life as we know it, but it's not gonna last forever. At these temperatures, the energized hydrogen atoms are moving so fast, they can't avoid smashing into each other. In the extreme heat and turmoil of the explosion, heavier elements are forged. Fusion at the core of a star generates the explosive force of a billion nuclear bombs every second. Every star is powerful, creating the basic matter for everything in the universe including us. There's still much more to be discovered about the mysterious objects called black holes The masters of the universe. Over hundreds of millions of years, each black hole grew, producing stronger gravity and pulling in more and more gas. Atoms release energy by fusing when they smash together. They fill the universe with stardust, the building blocks of life. The answer is an . Massive stars generate pressures and temperatures greater than anywhere else in the universe. How the Universe Works (2010) Season 9, Episode 2. As you get thinner and thinner and thinner, as you get closer and closer and closer, you're undergoing a process we call "spaghettification" because you're basically turned into a long, thin tube of pasta. Save my name, email, and website in this browser for the next time I comment. Planets 7. Temperatures at its core reach 15 million degrees. The building blocks of life. All life begins with stars. And this would be equivalent to me in Los Angeles looking at you in New York and seeing you be able to move your finger like this. The red spots you see are gas that's being spit out of the hole, into space. 27. By the time a star reaches the white-dwarf stage, the fusion process has stopped. The atoms in your left hand may come from a different star from the atoms in your right hand, but you are literally a star child. The Andromeda galaxy is our closest neighbor. If it points the camera forward, at first it sees only black, but as it moves toward the heart of the black hole, it encounters the most bizarre place in the universe. When massive stars 10 times heavier than our sun die, gravity crushes them, creating a huge explosion, a supernova. In 2004, NASA sent two robot explorers to Mars to find out. Posted at 01:41h . 22.giant crystals of __________________ are at the center of a white dwarf. You can find the polarity of a compound by finding electronegativities (an atoms desire for an electron) of the atoms; Carbon has an electronegativity of 2.5, compared to Fluorines A) Enter the the Ksp expression for the solid AB2 in terms of the molar solubility x. This, in turn, requires knowledge of its history, which started with the Big Bang. And, in fact, there are over 100 billion galaxies in the observable universe. a) Calculate the energy. When one of these stars dies, it sets off the biggest explosion in the universe A hypernova. You need that amount of gravity in order to compress the star to create fantastic amounts of heat sufficient to ignite nuclear fusion. "Keepers of the Flame" is Episode 3 of Innate: How Science Invented the Myth of Race , a podcast and magazine project that explores the historical roots and persistent legacies of racism in American science and medicine. The first episode features the story of how stars were made. What are the characteristics of the Solar System? The areas of research include astroparticle and high-energy astrophysics, plasma physics, and solar system astronomy and astrophysics. TV Show Figuring out how they work that's a whole different ball game. Seattle, Washington(WA), 98106. A singularity is basically a word for saying "I don't know. " It's a ball of superheated gas that's been lighting our solar system for 4. What you would see is a huge, swollen, bloated, red disk slowly reaching up over the horizon. Gravity keeps the pressure on, sucking in gas and dust particles that smash into each other, generating more and more heat. Then we might finally answer the question what lies at the heart of a black hole? The gravity of Betelgeuse is so powerful, it can smash together bigger and bigger atoms. Yes, the Kremlin and the CCP have committed public self-defeating errors in the past two years, but also in the past two years, the world watched as an American president summoned a mob to overturn a free and fair election and kill officers of the law. 24.when these massive stars explode its called a ________________ __________________ and it is the most violent even in the, 14. constant heat, pressure, and fuel are available, 15. theyre immense gravity holds them together. It's very exciting to be able to create in a laboratory the same sort of physics that are on the solar surface. And basically, what happens is, you get stretched out. And that means, in actuality, it's immense. You really can't get anything bigger or stronger or scarier than a black hole. They're so intense that if there was a gamma-ray burster in the region of our galaxy near our solar system, it could literally vaporize the entire planet. It would be like sticking your head in an oven set to "broil. " As the star rotates, the fields clash and burst through the surface. The explosion lasts just 1/100,000 of a second. Season 1. Once upon a time, people thought that black-hole physics was too fantastic to be true.

They're already picking up signals from the dark heart of our galaxy. When you heat up a gas, it tends to expand and it blows outward. This massive machine amplifies the power of a single laser beam That's enough power to supply And all that energy will be directed toward an area the size of a pinhead. The only way to find out more about black holes is to get a good look at one. But even a picture can't compare to witnessing it for yourself. The core of a massive star is a kind of factory, manufacturing heavier and heavier elements which is what also leads to the star's destruction. On a clear night in the country, if you're lucky, you can see maybe 3,000 stars. Galaxies (aka Alien Galaxies) 4. Born in violence, dying in epic explosions. 23.giant stars create the building blocks of the universe when they die. Black holes give physicists no end of headaches, 'cause they break all the rules. Your feet are being pulled much harder than your head, and you're like a piece of taffy being pulled between two strong people. Betelgeuse 300 times larger than Eta Carinae. If black holes are shortcuts through space and time, it could turn one of the coolest ideas from science fiction into reality. 10. 25. nuclear power are left after a supernova. It's called fusion, the same force that powers stars. And it's inside the largest stars. Slowly, inex orably, the universe will get colder and darker until the last star burns out and the universe becomes dark once again. They're third or fourth generation leftover debris shot into space by dying stars a long time ago. From Einstein's theories, we learned how to release the energy inside an atom. What are five common elements in stardust? Calculate the energy Calculate the wavelength. We once thought that black holes, like unicorns, could never be found. To be able to do this experiment, one has to be able to see the stars that are very close to the center of the galaxy and to position them incredibly accurately. 28 terms. Everything that you're made of, everything in the world around you is made of had to come from the belly of a star that blew up a long time ago. 04 The universe is made up of roughly 68% dark energy, 27% dark matter, and 5% normal matter.
