Black Holes
A black hole is a theoretical region of space in which the gravitational field is so powerful that nothing, not even visible light, can escape its pull after having fallen past its event horizon. Why don't you fall into the black hole library and see what they're all about? |

Cosmic Rays
Cosmic Rays... Are they aliens shooting at us? Are they really beams from space? The answer to both is no. They are particles of energy from a wide variety of sources. Why not come inside the Cosmic Ray Library and learn more? |

Supernova
It's the scariest thing in our galaxy! A supernova is a stellar explosion. They are extremely luminous and cause a burst of radiation that often briefly outshines an entire galaxy before fading from view over several weeks or months. During this short interval, a supernova can radiate as much energy as the Sun could emit over its life span! |
