I would rather own little and see the world than own the world and see little of it 我们宁愿拥有少一点也要去旅行
Our galaxy is rushing toward the great galaxy Andromeda, they are rushing toward each other. And they are going to encounter each other in a couple billion years. Abraham and his colleagues decide to try to simulate this clash of the Titans. This was
We've transported the earth 3 billion years into the future. The sky is dominated by a massive galaxy called Andromeda. The view looks peaceful enough. But whats about to happen is one of the greatest calamities in the universe. The clues lie in thes
Venus is closer to the Sun, Mars is farther from the Sun. And there is a zone in between, the blazing hot furnace Venus, the frigid Mars. That zone in between we call a habitable zone and the earth lies smack in that thing where water would be in liq
One type of giant planet orbits very close to its star, we call them hot Jupiters because these Jupiter-like planets are so close that they are blowtorched by the intense heat from the star. The other sort of planet we have found is also bizarre. Wev
So what we are looking at is a region about 200 million light years across which is actually just a small part of our really big simulation that we call Bolshoi which is Russian for big. Everything that you see here is actually completely invisible.
What happens is that, first the dark matter forms the structure, the ordinary matter then follows the dark matter. The ordinary matter is hydrogen and helium at this stage. And the hydrogen and helium fall/ to the center of the dark matter halos that
Its extremely frustrating because this region, this time period holds within it, in some sense, the rose headstone of / galaxy formation. But there are clues as to what was happening inside those dense hydrogen clouds. Look back even further in time
All of the galaxies, all of the stars, and gas and dust and planets, and everything else that we can see with our greatest telescopes represent about half of one percent of whats actually/out there. The rest is invisible. It is mostly some mysterious
They were once thought to mark the outer limits, but today astronomers believe the Milky Way galaxy is much bigger than what we can see. To understand why, we will travel to the stars of the outer galactic disc. Far from our usual place in space, we
To understand how these calamities occur, astronomers need to catch a massive star in its death throes. Astronomers are like detectives. We have to figure out what's going on in the universe, sometimes based on a minimum number of clues. And in the c
Once theyve caught the light of a dying star with their state of our telescopes. The detective work can begin. We collect that light and we analyze it in great detail in order to determine whats going on, whats the chemical makeup of the star, whats
