This Just In
The bright glint of alien oceans may be visible from afar, allowing astronomers to flag potentially habitable exoplanets.
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.'
The newly discovered planet called 51 Eridani B is about twice the mass of Jupiter, and orbits a star about 97 light-years from Earth.
Scientists are meeting this week to discuss landing sites for NASA’s next Mars rover, that will look for past life and stash rocky samples for Earth-return. These are some of the landing sites under consideration.
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.'
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.
