As astronomical techniques become more advanced, a team of astrophysicists think they will be able to not only detect the signatures of alien life in exoplanetary atmospheres, but also track its relentless spread throughout the galaxy.
If funded, the tiny Twinkle telescope will look at the atmospheres of close alien planets, including 'super-Earths.'
Astronomers said Thursday they had found a planetary system with three super-Earths orbiting a bright, dwarf star -- one of them likely a volcanic world of molten rock.
For the first time, astronomers have detected an aurora erupting beyond the solar system, giving us a profound glimpse at the magnetism surrounding a brown dwarf, or 'failed star.'
NASA’s Kepler space telescope has found the closest match yet to a world that is similarly sized to Earth and circling a sun-like star at the right distance for liquid surface water, a condition believed to be necessary for life, scientists said Thursday.
Thursday was a red letter day for exoplanet astronomers -- it was the day that marked the announcement of the discovery of Kepler-452b, an alien world that possesses more Earth-like traits than any exoplanet discovered before it.
You don't get to meet your double every day, but Jupiter and the sun share the same galaxy as their very own doppelgangers.
A planet about the size of Neptune but situated 33 times closer to its parent star than Earth orbits the sun is losing its atmosphere, forming a fat, comet-like tail in the process.
