Astronomy // 
Earthshine is light that’s reflected from the Earth to the moon, then back to the Earth again. Now scientists have discovered a way to use this shine to determine the amount of vegetation, water and cloud on our planet. Of course we already know this - but what’s significant is this technique could be used to analyse the surface of other far-off planets too.

Astronomy // 
Mars might look like a total desert of a planet, but scientists are finding more and more reasons to think that there's a lot more going on beneath the surface. Now, that's literally the case, after researchers at the Australian National University found that sub-surface of the Red Planet might hold greater potential for life within its soil and rock than our very own planet Earth.
