Europa hides an ocean of liquid water beneath its icy crust; NASA wants to seek out its life-giving potential. Continue reading →
Project aims to drop penetrating darts into planet surface.
Red dwarf stars -- the most common stars in the galaxy -- bathe planets in their habitable zones with potentially deadly stellar winds, a finding that could have significant impacts on the prevalence of life beyond Earth, new research shows.
Research suggests that some Earth microbes are hardier than expected. If they hitch a ride on spacecraft, they could colonize other celestial bodies in the solar system.
Earth may be a nice and cozy place for life as we know it to evolve, but is it really the best place for life to thrive? Probably not, say two researchers. Continue reading →
Hydrogen ions in the solar wind react with oxygen in interplanetary dust grains to form little packets of water, potentially supplying Earth with its water. Could stellar water factories supply exoplanets, too?
The site where NASA’s Mars rover Curiosity landed last year contains at least one lake that would have been perfectly suited for colonies of simple, rock-eating microbes found in caves and hydrothermal vents on Earth.
The Doomsday Clock is well and truly ticking for planet Earth as our sun ages and gets hotter. Continue reading →
