Exoplanets — A complete guide and latest news

Thanks to groundbreaking models and the James Webb Space Telescope, scientists are poised to explore their mysterious evolution and reveal clues about planetary formation across the galaxy.

Using the James Webb Space Telescope, astronomers have made the shock discovery that giant rogue exoplanets can grow their own planetary systems without needing a parent star.

"This discovery was partly serendipity! But, we believe there are many more such opportunities hidden in Hubble data."

A super-Earth exoplanet has been detected within the habitable zone of a nearby red dwarf star, where liquid water might exist on its surface under the right atmospheric conditions.

Astronomers have discovered a baby exoplanet "spiral architect" carving complex swirls into a disk of gas and dust around the young star HD 135344B.

Astronomers have used the Chandra X-ray telescope to observe an exoplanet as it disintegrates because its parent star is bombarding it with radiation.

A massive doomed exoplanet on a death spiral toward its parent star has three possible catastrophic fates.

A monster exoplanet as big as 10 times the size of Jupiter has emerged from the stellar gas and dust surrounding a young star, thanks to the telescope tag team of Gaia and ALMA.

Some planets take the expression "you're your own worst enemy" to the extreme — triggering stellar flares from their own parent stars by being too clingy.

With the aid of NASA's exoplanet-hunter TESS, citizen scientists have discovered a new gas giant that is cool, literally and figuratively.
