Some stars are just born with extremely magnetic personalities.
In the search for Earth-like worlds beyond the solar system, Kepler-438b seems to have it all. Alas, its angry star is a poor host for any potential lifeforms.
Red dwarf stars may be able to support habitable exoplanets after all -- through complex tidal interactions between star and planet, global magnetic fields could evolve, protecting hypothetical life forms from the red dwarfs' ferocious nature.
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.
