History was made Wednesday when the European Space Agency successfully landed a spacecraft on a comet for the first time ever.
"We're are on the comet!" #cometlanding

"We are the first to do this - and that [achievement] will stay forever." said Jean Jacques Dordain, Director General of ESA.
"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."
