Chandra: Event Horizon (5:38)
Watch this NASA video to learn what a black hole and how it works. Black holes are created whenever matter collapses onto itself. When anything gets too close it gets pulled in - even light. How close is too close? That's called the event horizon.
Chandra: All About Supernovas (4:39)
Watch this NASA video to learn about supernovas. When these supernovas are formed, they can be the brightest thing visible in the universe. In our own galaxy, we can see supernovas about twice a century (although the last one recorded was in 1604).
Chandra: All About Stars (4:13)
Watch this NASA video to learn more about stars. Stars are balls of hot gas, and the don't just give off visible light, but rather all wavelengths of light. Watch this video to better understand how stars work.
Creating Pictures of Space (3:31)
Watch this NASA video to see how scientists create images of space. NASA scientists, like Dr. Robert Hurt, have the job of taking colors that we can't see (ultraviolet and infra-red light for example) and assigning them to colors that we can see.
Spitzer: Star Wars Sunsets (2:32)
Who can forget the scene in Star Wars where Luke is contemplatively gazing across the Tatooine desert towards a sunset with two suns. See why NASA scientists are now convinced that the universe is full of planets with twin sun sunsets.
