Meanwhile enjoy Rosetta's landing on a comet. For the first time in history, a spacecraft from Earth has landed on the face of a comet speeding through deep space.

The European Space Agency's Philae lander on the Rosetta spacecraft made its nail-biting, history-making touchdown on the Comet 67P/Churyumov-Gerasimenko today (Nov. 12) and quickly fired its harpoons into the icy target to anchor itself on the strange landscape. The landing ended what some scientists had dubbed "seven hours of terror" - the time it took for Philae to descend from Rosetta as the spacecraft and comet flew through space about 317 million miles (510 million kilometers) from Earth.
