Microbes From Ambient-pressure Analogues Offer Insights Into Possible Life In Europa’s High-pressure Subsurface Ocean

by Keith Cowing

Under its thick ice layer, Europa contains a shielded liquid water ocean where habitable conditions may exist. To effectively assess the habitability of this environment and the implications on putative […]

Elevated Eccentricities In The Radius Valley Hint At Water-Rich Mini-Neptunes

by Keith Cowing

While recent planet-formation models broadly reproduce the observed population of super-Earths and mini-Neptunes, as well as the bimodal radius distribution (the “radius valley”), it remains unclear whether all these planets […]

During Snowball Earth Early Life May Have Sheltered In Meltwater Ponds

by Keith Cowing

When the Earth froze over, where did life shelter? MIT scientists say one refuge may have been pools of melted ice that dotted the planet’s icy surface.
