Exoplanets

Five years since the Kepler Space Telescope was retired, a team of astronomers believe they’ve found exoplanets captured by some of the veteran observatory’s last light.What Is Planet Nine and Why Can’t We Find It?Kepler launched to…

TRAPPIST-1b is a superhot rocky world just 40 light-years away. Astronomers recently trained the Webb Space Telescope this exoplanet, a world in the TRAPPIST-1 star system, and found that it’s devoid of an atmosphere.The finding could…

The Webb Space Telescope just turned its infrared gaze at an exoplanet and found dense clouds swirling in the atmosphere of this quirky world.The planet—VHS 1256b—has a 22-hour day but sits extraordinarily far from the two stars it…

The hunt for exoplanets has apparently led to a few near misses. MIT researchers have discovered that three "planets" observed using the Kepler Space Telescope (Kepler-699b, Kepler-840b and Kepler-854b) are more likely to be small…

Astronomers have mapped the atmospheres of exoplanets for a while, but a good look at their night sides has proven elusive — until today. An MIT-led study has provided the first detailed look at a "hot Jupiter" exoplanet's dark side by…

Many exoplanets are completely uninhabitable, but they can still be useful in the search for more hospitable worlds. Scientists at Lund University have created a 3D map of ultra-hot gas giant WASP-189b's atmosphere that could provide…
