There’s a red dwarf about 35 light-years from here that’s spewing powerful, life crushing solar flares into space. These types of stellar objects are fairly common, leading to speculation that our galaxy is less habitable than we thought.
Astronomers have spotted a Neptune-sized planet with a rather unexpected feature—a comet-like tail that trails for millions of miles. Nothing quite like it has ever been seen before.
Red dwarfs stars, the most common stars in the galaxy, are bathing planets in their habitable zones with potentially deadly stellar winds, a finding that could have an impact on finding life beyond Earth.
Canadian astronomers have discovered a gigantic planet-like object that's so far from its parent star that it takes 80,000 years to complete a single orbit — a distance that's 50 times farther than Pluto is from our sun. The discovery may force a re-think into how and where planets are capable of forming.
Let's say you're a planetary scientist searching for signs of life on other worlds, and you happen upon an exoplanet whose atmosphere contains a large proportion of oxygen. Jackpot, right? Not exactly. New research shows planets orbiting red dwarf stars may harbor signatures of life (like oxygen) that are actually…
A new study has effectively doubled the estimated number of life-friendly planets in orbit around red dwarfs. And remarkably, the astronomers attribute the revised figure to the presence of clouds.
When we look up into the starry sky at night, we only see a small portion of what's really up there. Red dwarfs comprise nearly 75% of all the stars in the Milky Way, yet they remain invisible to the naked eye. Given their predominance, astronomers and astrobiologists are keen to learn more about these small, cool…
A team of scientists using the United Kingdom Infrared Telescope (UKIRT) in Hawaii have found four different pairs of binary systems whose stars are so close to each other that it takes them less than four hours to orbit one another. Previous estimates indicated that stars shouldn't be allowed to do this — they…
Check out that extra-bright galaxy towards the top of this image. That's an elliptical galaxy, which are among the largest galaxies in the universe. And now scientists believe these galaxies hold five to ten times more stars than previously thought.
