Based on new simulations, scientists believe that giant gas planets across the universe can often collide and merge into even bigger gas plants — behemoths called "super-Jupiters." In the cosmic ...

An international team of astronomers has discovered a distant planetary system that challenges long-standing theories of how planets form. Across our galaxy, astronomers routinely observe a ...

Since the first discovery of planets beyond the solar system in 1995, more than 6,000 exoplanets have been identified. Many of these planets have properties that differ significantly from the eight ...

New research using NASA’s James Webb Space Telescope examines the maximum sizes of gas giant exoplanets, measuring chemical compositions and formation processes in the HR 8799 system.

Astronomers just discovered a gas giant on its way to becoming a hot Jupiter — and it’s extremely weird. An exoplanet on a twisted, backwards orbit may offer clues about how hot Jupiters (giant gas ...

(CN) — In a study published in the Astronomical Journal on Monday researchers explain how their detailed chemical analysis of gas giants in a solar system some 130 light years away sheds light on the ...

Rogue planets may be more common than we thought, and they may form alone in the void in the same way stars do, suggests a recent study. We think we know how the universe is structured: Moons orbit ...

The birthplaces of planets are disks made out of gas and dust. Astronomers study these so-called protoplanetary disks to understand the processes of planet formation. Beautiful images of disks made ...

Planets may begin forming much earlier than scientists once believed during the final stages of a star s birth, not afterward. This bold new model, backed by simulations from researchers at SwRI, ...

ESA’s CHEOPS mission has uncovered a surprising rocky planet at the outer edge of the LHS 1903 system. Located 116 light-years away, the discovery defies expectations that outer planets are gas giants ...
