Early Earth's Haze May Give Clue to Habitability Elsewhere
Seattle WA (SPX) Nov 12, 2015
An atmospheric haze around a faraway planet - like the one which probably shrouded and cooled the young Earth - could show that the world is potentially habitable, or even be a sign of life itself. Astronomers often use the Earth as a proxy for hypothetical exoplanets in computer modeling to simulate what such worlds might be like and under what circumstances they might be hospitable to life. In new research from the University of Washington-based Virtual Planetary Laboratory, UW doctoral student ... read more
