An artist's illustration of TRAPPIST-1d takes you to the surface of the third planet from the red TRAPPIST-1 star. From here, the star looms larger than our sun and its light casts a red glow across the sky. Look up, and you may catch a glimpse of its six sister planets, as visible as our moon is from Earth. With click or touch, descriptions will appear for each point of interest.
A star among planet hunters, Natalie Batalha wields a formidable weapon: NASA’s Kepler space telescope.
"I think when you find a question you’re interested in pursuing, be brave and pursue it." The co-lead of NASA’s Kepler space telescope, Jessie Dotson, has pursued asteroids and exoplanets, and a lot more besides.
A team of scientists led by the Carnegie Institution for Science has released the largest collection of observations for hunting exoplanets to the public.
University of Warwick researchers have identified a white dwarf pulsar – a star type which has eluded astronomers for half a century.
The vortex coronagraph has the potential to image planetary systems closer to their host stars than any other instrument in the world.
New results from the 229th American Astronomical Society meeting reveal that Earth-sized planets can be made of minerals that are distinctly not Earth-like.
Our nearest neighboring star Proxima Centauri bears a startling resemblance to our own sun, raising questions about conditions on its Earth-sized planet.
Go beyond what's possible; that's the Spitzer Space Telescope's motto. Designed for a two-year mission, 13 years later it's still searching the skies for new discoveries.
The relatively nearby planet GJ 1132b may have an atmosphere despite being baked to a temperature of around 450 degrees Fahrenheit.
Astronomers have pinpointed which planets discovered by the NASA Kepler mission may sustain liquid water on their surfaces.
To find Earth-like planets, NASA will face a challenge that seems impossible: build a space telescope so stable, it moves less than the width of an atom.
A young star's stellar outburst brings its water snow line into view. The bizarre idea of snow orbiting in space is fundamental to planet formation.
Astronomers from UC Santa Cruz have found the first strong evidence of water vapor or ice in the the coldest known object outside our solar system– a brown dwarf five times the size of Jupiter.
How do some gas giant planets end up so feverishly close to their stars? NASA's Spitzer Space Telescope finds new clues.
A giant 'Tatooine' discovered by NASA's Kepler mission is the largest world yet discovered that circles two stars.
The organic molecule methyl alcohol (methanol) has been found for the first time in a young planet-forming disc.
A team of astronomers has found that there are far more planets of the hot Jupiter type than expected in a dense cluster of stars called Messier 67.
Venus has an “electric wind” that may have played a significant role in stripping Earth’s twin planet of its oceans.
