New observations of "forbidden" planet TOI5205-b reveal surprising details about it its atmospheric chemistry.

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered an extrasolar planet orbiting TOI-4616—a nearby M-dwarf star. The newfound alien world, ...

Astronomers have recently uncovered a remarkable planetary system around the faint orange star WASP-132, featuring two exoplanets that couldn’t be more different. One is a rocky world that completes ...

Earth’s history has been punctuated by at least five major ice ages. Some of these frigid periods of prolonged global cooling saw much of our planet locked in ice and snow for 100 million years. It ...

What happens when a planet defies every expectation of how worlds are supposed to form and move? In the nu Octantis system, astronomers have confirmed the existence of a planet that orbits in the ...

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 ...

Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other ...

A planet circling at a sharp 90-degree angle to the orbits of its two host stars has now been confirmed. This discovery challenges long-standing ideas about how planets form and orbit in the cosmos.

Astronomers from the Massachusetts Institute of Technology (MIT) have made an unusual discovery, finding a planet which is in the process of disintegrating. And as it decays, it is leaving behind a ...
