Earth-Sized Planet Found At One of the Lightest Red Dwarfs

Artist’s conception of a rocky Earth-mass exoplanet like Wolf 1069 b orbiting a red dwarf star. If the planet has retained its atmosphere, chances are high that it would feature liquid water and habitable conditions over a wide area of its dayside.

Astronomers have found another Earth-sized planet. It’s about 31 light-years away and orbits in the habitable zone of a red dwarf star. It’s probably tidally locked, which can be a problem around red dwarf stars. But the team that found it is optimistic about its potential habitability.

XMM Newton Catches a Tiny Flare Star in Action

Sometimes, even small stars can pack a mighty punch. And in the case of a flare star, the results can be awesome. Very awesome.

Astronomers uncovered just such an anomaly recently, culling through data from the European Space Agency’s XMM-Newton orbiting X-ray observatory: the first X-ray flare from a distant cool L-dwarf type star.
