Exoplanets

A new study has identified an exoplanet that is just 3 million years old — around 1,500 times younger than Earth — alongside a misaligned protoplanetary disk that researchers cannot explain.

Astronomers using the James Webb Space Telescope have detected possible signs of gases released by volcanic activity on a distant exoplanet.

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.
