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

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

It's just 18 light-years away: a super-Earth named GJ 251c with a minimum mass about 3.84 times that of our own planet. The ...

The search for an unknown planet in our solar system has inspired astronomers for more than a century. Now, a recent study suggests a potential new candidate, which the paper’s authors have dubbed ...

Many of the most interesting bodies in our Solar System aren’t planets, but the moons that orbit them. They have active volcanoes, hydrocarbon oceans, geysers, and moon-wide oceans buried under icy ...

The NASA/ESA/CSA James Webb Space Telescope has provided the first direct measurements of the chemical and physical properties of a potential moon-forming disk encircling a large exoplanet. The carbon ...

Astronomers found an atmosphere where they least expected it—clinging to an exoplanet that’s too small, too hot and too old to have air, at least in theory. James Webb Space Telescope (JWST) ...

The official number of exoplanets—planets outside our solar system—tracked by NASA has reached 6,000. Confirmed planets are added to the count on a rolling basis by scientists from around the world, ...

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 ...

Earth-like planets on non-Earth-like orbits might be just as likely as Earth to harbor life—maybe even more likely. Given the abundance of non-circular orbits among exoplanets—with half of all gas ...

The classical picture of star and planet formation suggests that a star’s rotational axis and the orbital planes of its planets should be aligned. However, exoplanetary systems have considerable ...

Recently identified exoplanet, BD+05 4868 b, is shedding its surface in a comet-like tail as it disintegrates under extreme stellar heat. SETI Live host Beth Johnson spoke with National University of ...
