Scientists have found water ice on an asteroid for the second time in just six months.
The discovery suggests that such ice is more common on asteroids in our section of the solar system than previously thought – and that such asteroids may have delivered much of the essentials for early life to Earth.
Two research teams found evidence of water and organic molecules on asteroid 65 Cybele.
Six months ago the teams made a similar discovery on a different rock – asteroid 24 Themis – for the first time.
