Moon's 'earthshine' may help the search for alien life

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.
