Lying beyond Pluto, 2026 ED138 could be as large as 1,500 kilometers in diameter. Astronomers are still working to confirm whether it meets the criteria for a dwarf planet.

Exoplanets extremely close to their stars are expected to have lost their atmospheres. But one of them, TOI-561 b, seems to have a thick atmosphere. Understanding how this super-Earth has an atmosphere is challenging.

Get ready for the age of private space telescopes. The Lazuli Space Telescope will launch in a few years and part of its mission is to observe exoplanets.…

A new study suggests that some of the heaviest rocky planets ever reported may not be as heavy as they look. These so-called 'mega-Earths,' rocky planets weighing more than about 10 Earths, could be an illusion created by activity on their host stars.…

New simulations suggest that the planets' orbits will destabilize well before the Sun expands into its red giant phase.

Scientists say moons around rogue planets wandering through the galaxy could remain warm enough for life thanks to tidal heating and hydrogen-rich atmospheres.…

The familiar concept of a planetary core, a small, dense metallic heart we take for granted, may be the exception rather than the rule for exoplanets.

A planetary odd couple — a mini-Neptune and a hot Jupiter — probably formed much farther away from their star before migrating closer in.

A new study may redefine how we classify Uranus and Neptune, suggesting that they may no longer be referred to as ice giants due to their rocky atmosphere, indicating a different composition.

I have recently entered 12th grade, and I've been obsessed with exoplanets for a while now. Not in a...

The Hubble Space Telescope has reached the jaw-dropping milestone of discovering more than 6,000 new worlds.

There's so little we know about circumbinary planets—planets that orbit two stars instead of one—that they can feel like the stuff of fantasy.…

The search for Earth 2.0 has begun in earnest. But there’s a huge variety of exoplanets out there, so narrowing down the search to focus valuable telescope time on only the best candidates is critical.…

A bizarre planetary pairing 190 light-years away is challenging everything astronomers thought they knew about how worlds form. A “lonely” hot Jupiter — typically found without nearby companions — is sharing its system with a smaller mini-Neptune tucked…

From Dev.to - machinelearning: An AI Pipeline Named RAVEN Just Pulled 31 New Planets Out of NASA TESS Data and Counted the Neptunian Desert

Kepler and TESS showed us that there's a radius gap in the exoplanet population. There are very few planets between 1.5 and 2 Earth radii, according to the data. But new research shows that the gap may not be as significant as thought.

Astronomers found 27 potential worlds orbiting two stars, suggesting twin-sun planets might not be quite so rare.
