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.

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…

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.

Astronomers identify 27 potential circumbinary planets orbiting two stars, offering real-life parallels to Star Wars’ Tatooine and expanding the search for exoplanets.

In 2006, the IAU defined "planet" for the first time, excluding Pluto and all other dwarf planets. In 2026, is it now time for a change?

Previously Pluto was the only such body thought to have supported an atmosphere, due to its stronger surface gravity.

The findings could more than double our current database of worlds that loop around binary star systems. But researchers need to analyze more data before they can officially celebrate a new trove of far, far away exoplanets

A study of NASA’s TESS (Transiting Exoplanet Survey Satellite) data on stellar pairs undergoing mutual eclipses has uncovered more than two dozen candidate
