Jupiter-like planet 8 UMi b, named Halla, orbits its host red giant star Baekdu closely. The red giant's merger with a white ...

This illustration shows an exoplanet orbiting around two brown dwarfs –– objects bigger than gas-giant planets but too small to be proper stars. ESO/M. Kornmesser Astronomers have discovered a ...

The James Webb Space Telescope has detected clouds made of silicates, similar to sand here on Earth, as well as water, ...

This artist’s impression shows a Jupiter-like exoplanet that is on its way to becoming a hot Jupiter — a large, Jupiter-like exoplanet that orbits very close to its star. NOIRLab/NSF/AURA/J. da Silva ...

Astronomers have detected an exoplanet with a highly oblong orbit that experiences wild temperature swings — and it may be transitioning into another type of world. The exoplanet, named TIC 241249530 ...

For the first time ever, the James Webb Space Telescope has discovered an exoplanet by directly imaging it. The newfound world has a mass roughly similar to Saturn and orbits inside the debris disk ...

Scientists are observing an Earth-like exoplanet that may contain water using NASA's James Webb Space Telescope, the space agency said in a news release. The exoplanet, known as TRAPPIST-1 e, orbits ...

Astronomers in Japan have spotted a distant object orbiting the Sun far beyond Neptune, pointing to an extraordinary event that took place during the earliest years of the solar system. Astronomers ...

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 ...

NORFOLK, Va. — This week will bring a celestial parade, full planetary alignment. The alignment will involve Mercury, Venus, Mars, Jupiter, Saturn, Uranus, and Neptune appearing in an arcing line from ...
