Exoplanets

A new analysis of a peculiar metallic cloud surrounding the exoplanet WASP-49 b provides further evidence that it may have been birthed by a volcanic satellite, which may become the first officially recognized "exomoon."

Using NASA's exoplanet-hunting spacecraft, TESS, astronomers and citizen scientists have discovered a record-breaking system of three tightly bound stars that could fit between the sun and Mercury.

The rocky planet, roughly twice Earth's size, has offered astronomers a glimpse of one of Earth’s possible futures — if it doesn’t get engulfed by our expanding sun.

"Our observations indicate the presence of powerful iron winds, probably fuelled by a hot spot in the atmosphere."

The Very Large Telescope in northern Chile imaged a "super-Jupiter" exoplanet called 2M1207b, precisely 20 years ago this week. This was the first direct visual confirmation of a world beyond our solar system.

NASA's Chandra X-ray space telescope has created a 3-D map of nearby stars that may help astronomers search for alien planets with the potential for life.

Located 50 light-years from Earth, the beady-eyed exoplanet LHS 1140 b could be a perfect candidate for discovering liquid water outside the solar system, new research suggests.

The James Webb Space Telescope revealed that the hot Jupiter exoplanet HD 189733 b, located just 64 light-years from Earth, has an atmosphere full of hydrogen sulfide, meaning it likely smells of rotten eggs.

Slovakian artist Martin Vargic's spectacular new infographics artistically portray, visualize and compare more than 1,600 planets in other star systems.
