Within hours of its landing, samples of the Winchcombe meteorite had been recovered and its origins tracked back beyond Mars to the asteroid belt.
A study has found that microorganisms living on Mars billions of years ago may have left the planet uninhabitable.
Believe it or not, this sort-of happened before in Earth’s history – and now we have the Moon.
In the void of interstellar space, the most distant emissary of humankind carries a message that will last for billions of years.
The unusual planetary system has a host star orbited by two giants. One has an incredible odd route around its star. And the other (unlike our own gas giants) is hellishly hot.
When the meteor exploded into pieces above New Zealand, it produced a shock wave strong enough to be picked up by earthquake seismometers. But any fragments have likely dropped into the ocean.

Most of what we know about planets outside our Solar System relates to gas-giant planets. A new study has identified and characterised a smaller exoplanet.
Tiny pieces of an asteroid have revealed an unlikely origin for much of the water in Earth’s oceans.
Saturn, Jupiter, Neptune and Uranus all have rings.
The fastest things ever made by humans are spacecraft, and the fastest spacecraft reached 330,000 mph – only 0.05% the speed of light. But there are ways to go faster.
It can get very cold in space.
