Foom! Superflares' Erupt From Tiny Red Dwarf Star, Surprising Scientists

Don't get too close to this little star! In April, a red dwarf star sent out a series of explosions that peaked at 10,000 times as powerful as the largest solar flare ever recorded. The tiny star packs a powerful punch because its spin is so quick: it rotates in less than a day, or […]

In this assembly of images taken with Hubble's Advanced Camera for Surveys, scientists have utilized both visible and infrared light to survey a most unusual galaxy. When looking for a newly formed galaxy in our “cosmic neighborhood”, they spied DDO 68 (a. k. a. UGC 5340). Normally to witness […]

Did Wild Weather Or A Companion Cause Eerie Infrared Glow From This Baby Star?

Watch out! Carbon monoxide gas is likely fleeing the disk of a young star like our Sun, producing an unusual signature in infrared. This could be the first time winds have been confirmed in association with a T Tauri star, or something else might be going on. Because the observed signature of the star (called […]

Wow! Water Ice Clouds Suspected In Brown Dwarf Beyond The Solar System

What are planetary atmospheres made of? Figuring out the answer to that question is a big step on the road to learning about habitability, assuming that life tends to flourish in atmospheres like our own. While there is a debate about how indicative the presence of, say, oxygen or water is of life on Earth-like […]
