Surprise! Saturn’s huge moon Titan may not have a buried ocean after all
"We're not certain if having widespread liquid pockets instead of a global ocean makes Titan more or less habitable."
Which exoplanet in the TRAPPIST-1 system could be habitable? Scientists are modeling the star to find out
Frequent flares from the nearby star TRAPPIST-1 could offer new clues in the search for habitable planets beyond Earth.
Beyond the habitable zone: Exoplanet atmospheres are the next clue to finding life on planets orbiting distant stars
But being in this sweet spot doesn't automatically mean a planet is hospitable to life.
SETI’s ‘Noah’s Ark’ – a space historian explores how the advent of radio astronomy led to the USSR’s search for extraterrestrial life
An expert dives into the history of radio astronomy and the search for life beyond our Earth.
Scientists want to search for life in this double star system devoid of giant exoplanets. Here’s why
The giants might've been kicked out, left to live a rogue lifestyle.
Planets may make their own water as they form — could that mean more habitable worlds in the universe?
New lab experiments suggest that water may not be a rare visitor delivered by chance but rather a fundamental ingredient woven into the process of planetary birth.
Heat leaking from Saturn’s ocean moon Enceladus bolsters its case as an abode for life
Excess heat detected at Saturn moon Enceladus' north pole helps to account for a finely balanced energy budget that keeps the moon's ocean liquefied. What could this mean in the search for life?
Powerful solar storms may help life get going on alien planets. Here’s how
New observations of a volatile young star have shown how infant suns could unleash enough energy to trigger biologically relevant chemical reactions in an orbiting planet's atmosphere.
Could these mysterious flashes of light in 1950s photos be UFOs? Some researchers think so
Researchers claim flashes of light seen in sky surveys could have been UFOs drawn to Earth by nuclear tests, but more mundane explanations should be explored first.
