Biosignatures & Paleobiology: February 2014

Although liquid water covers a majority of Earth's surface, scientists are still searching for planets outside of our solar system that contain water.

Astrobiologists supported by the NASA Astrobiology Institute have shown that mineral species on the early Earth may have been different than the ones found on our planet today.

The atmospheric composition of transiting exoplanets can be characterized during transit by spectroscopy.
