What is the Philae probe looking for on the 67P comet?

The Philae probe has successfully landed on the 67P comet after a ten year journey to get there.

It had a bit of a bumpy landing but has already started to send data back to Earth.

But what are scientists hoping to learn from the mission?

Space Scientist Maggie Aderin-Pocock and Dr Sarah Crowther from the University of Manchester tell Newsround more about the kind of thing the probe is looking for.
