The stellar runts of the galaxy probably aren't so great for nurturing Earth-like worlds, say scientists running new simulations of the formation of planets around a variety of stars.
Does it exist or not? Astronomers are claiming that the potentially habitable exoplanet is just noisy data, while others say it's too early to discount the existence of Gliese 581d.
Astronomers have discovered a star that carried out a stellar hit-and-run 70,000 years ago... and our solar system was the victim.
New research suggests that the frozen cores of 'mini-Neptunes' could be transformed into habitable worlds with a little help from their red dwarf hosts.
Astronomers have detected a huge array of exoplanets of different sizes -- now we are on the verge of detecting worlds of different shapes.
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.
NASA's Kepler space telescope has discovered a veritable menagerie of alien worlds orbiting other stars, but this most recent exoplanetary find is perhaps one of the strangest.
The space telescope has imaged the nearest star to the sun, Proxima Centauri, but it's still just a point of light shining in the night. Continue reading →
