After losing its gaseous envelope, the Earth-size core of an exoplanet formed a second atmosphere. It’s a toxic blend of hydrogen, methane, and hydrogen cyanide that is likely fueled by volcanic activity occurring beneath a thin crust, leading to its cracked appearance.

This is an artist’s impression of exoplanet WASP-189 b orbiting its host star. The star appears to glow blue because it’s more than 2,000 degrees hotter than our sun. The planet, which is slightly larger than Jupiter, has a tilted orbit around the star’s poles rather than its equator.

This illustration shows a carbon-rich planet with diamond and silica as ts main minerals. Water can convert a carbon-rich planet into one that’s made of diamonds. In the interior, the main minerals would be diamond and silica (a layer with crystals in the illustration). The core (dark blue) might be made of an iron-carbon alloy.

Welcome to the KELT-9 system. The host star is a hot, rapidly rotating A-type star that is about 2.5 times more massive and almost twice as hot as our sun. The hot star blasts its nearby planet KELT-9b with massive amounts of radiation, leading to a daylight temperature of 7800 degrees Fahrenheit, hotter that most stars and only 2000 degrees cooler than the sun.

This is an artist’s rendering of the Proxima Centauri planetary system. The newly discovered super-Earth exoplanet Proxima c, on the right, has an orbit of about 5.2 Earth years around its host star. The system also comprises the smaller Proxima b, on the left, discovered in 2016. Illustration by Lorenzo Santinelli.
