By studying it, astronomers can find out all sorts of things - from the temperature of a star and the chemicals it contains, to the shape of a planet's surface.Explaining it allTo explain how the universe works, astronomers come up with theories. These are then backed up by evidence from telescopes., lab experiments, or complicated models run on supercomputers.The universeThe universe expanded from a tiny dot, in a mind-blowing event called the Big Bang. But what shape is the universe? How might it end? And could there be more than one?GravityGravity holds the universe together, interacting with space and time. Black holes are the regions where gravity is strongest. What would happen if you fell into one?Is anybody out there?Searching for aliens starts with a search for water, because all life we know depends on it. At the same time, people listen out for alien signals, as well as planning their own adventures in space.Astronomy and youGet stuck into astronomy from your own home, or choose your ideal astronomy career.
