Astronomers have used the James Webb Space Telescope (JWST) to observe an oddball gas giant exoplanet orbiting a dead star.

Astronomers have discovered two "super-puff" exoplanets orbiting the same star with densities lower than cotton candy.

When astronomers discovered a giant planet orbiting a dead star in 2020, they wondered how it survived its star's violent demise. Now, observations from NASA's James Webb Space Telescope (JWST) may ...

A gas giant planet called WD 1856b, orbiting the burned-out core of a dead, sun-like star. And in a new study published today in Nature, researchers report an even wilder discovery: Not only is WD ...

The James Webb Space Telescope has detected methane in the atmosphere of TOI-199 b, a Saturn-mass gas giant orbiting its star ...

Webb captures dramatic temperature spikes on HD 80606 b, one of the most extreme giant planets ever discovered.

Exoplanets are planets that orbit stars other than the sun and thus exist outside the solar system. The word "exoplanet" ...

(Nanowerk News) Gas giants are large planets mostly composed of helium and/or hydrogen. Although these planets have dense cores, they don’t have hard surfaces. Jupiter and Saturn are the gas giants in ...

One way gas giants form is through core accretion, where solid cores gradually grow in a disk by pulling in rocky and icy pebbles until they become massive enough to attract the gas that surrounds ...
