Martian meteorite may contain evidence of extraterrestrial life

NASA rover Curiosity is beavering away up on Mars, examining rocks, drilling holes, checking out the weather — but it’s not just up there to look at the planet’s hospitability for humans. It’s also looking for conditions favourable for life; not now, but in the past, when Mars may have been home to extraterrestrial microbes.

But maybe the answer is right here on Earth, after all — in the form of a meteorite.
