Moon's 'earthshine' may help the search for alien life
Quote:
Studying reflected light, using giant lunar 'mirror,' works on Earth, and maybe in universe
Astronomers have managed to detect the telltale fingerprints of organic life on Earth
using a new technique that examines sunlight reflected onto the moon by our planet.<snip>
Earthshine observations have been done before,
but Sterzik and his colleagues took it one step further,
and developed a new approach to take into account the polarization of the light,
which enabled them to make more detailed and sensitive measurements.
The so-called "earthshine" observations may pave the way for a similar tool
to help spot signs of alien life in the universe, scientists say.

Of course, they could have just looked through the other end of the telescope.
