Tweet of the Day: Rosetta’s Space Probe Successfully Lands on Comet
History was made Wednesday when the European Space Agency successfully landed a spacecraft on a comet for the first time ever.
The comet, 67P/Churyumov–Gerasimenko, orbits, the sun every 6.45 years. It is 2.1 miles wide by 2.4 miles long.
Rosetta first launched in 2004 to research the comet, and it didn't arrived at its destination until this past August. On Wednesday morning, Philae first separated from the probe to attempt a landing.
Researchers are hoping to learn more about the origins of the solar system and whether or not comets could have brought water and life to Earth. Watch an ESA animated explanation of Rosetta's journey to the comet and it's surface mission below.
The comet has also been emitting a strange "song" into space, which has surprised scientists.
"We're are on the comet!" #cometlanding

The comet has also been emitting a strange "song" into space, which has surprised scientists.
"The scientists think it must be produced in some way by the activity of the comet, as it releases neutral particles into space where they become electrically charged due to a process called ionisation. But the precise physical mechanism behind the oscillations remains a mystery."But it's obviously aliens trying to communicate with us, right? Hopefully the message isn't "Warning: Do not land on this comet."
