You can depend on Sky & Telescope’s editors and bloggers to provide accurate, in-depth reports on important astronomy news — instead of sound bites, we'll give you what you need to really understand the latest space events, whether they be observations from Mars orbiters, the discovery of what’s to blame for powerful cosmic explosions, or just when a passing asteroid will block out a faraway star.

Bioluminescence and cosmic light, by Phil HartAstrobiology

Astrobiology is the study of life’s origins and how extraterrestrial life might develop on other planets in and beyond our solar system. Though this field of study has only one life-hosting world – so far! – that’s not stopping researchers from investigating what kinds of alien life might be possible.
