Astronomers announced this week they found a water-rich and relatively nearby planet that's similar in size to Earth.

An international team of scientists has observed four super-massive black holes at the center of galaxies, which may provide new information on how these central black hole systems operate.

The Cassini mission completes a flyby of Saturn's moon Enceladus, sending back data and stunning images of the rippling terrain.
