A space probe landed on a speeding comet for the first time ever on Wednesday morning. More than a decade ago, Rosetta and a lander called Philae set off to find the commit 67P/Churyumov–Gerasimenko. The European Space Agency's Philae lander separated from the Rosetta orbiter at 09:03 GMT on Tuesday and touched down on the speeding comet around 4:00 GMT.

Scientists hope that exploring the comet will answer questions about how planets are formed.
