The role that Earth's oceans have on our planet's habitability is undeniable, but now scientists think that exoplanetary oceans are essential for alien life to evolve. Continue reading →
In the case of a newly-discovered exoplanet orbiting a star only 16 light-years away, although astronomers may call it 'habitable,' it's likely anything but. Continue reading →
A year after being sidelined by a positioning system failure, NASA’s planet-hunting Kepler space telescope is back at work on a new and expanded mission called K2.
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.
Meet 'mega-Earth,' a souped-up, all-solid planet that, according to theory, should not exist.
In an effort to better understand the atmospheres of worlds orbiting other stars, NASA's Cassini mission is using sunsets through the hazy atmosphere of Saturn's moon Titan to create a solar system 'exoplanet analog.' Continue reading →
Curious about whether there is life beyond Earth? The answer should come within 20 years, astronomers told members of a Congressional science committee on Wednesday.
An exoplanet that orbits its star at a whopping distance of 2,000 times the sun-Earth distance has been discovered -- as far as exoplanets go, that's the most extreme orbit found to date. Continue reading →
