Did 29 Cygni b form like a planet, or like a star? Or are the two not quite as distinct as previously believed?

A new experimental study published in Geochimica et Cosmochimica Acta reveals that Mercury’s sulfur-rich interior behaves in ...

An international team led by Dr. Indrani Das of Academia Sinica Institute of Astronomy and Astrophysics (ASIAA) has shown, ...

The JWST discovers an impossible anomaly on TOI-5205 b and challenges everything we thought we knew about giant planets.

Planets, like those in our solar system, form in a bottom-up process where small bits of rock and ice clump together and grow larger over time. But the heftier the planet, the harder it is to explain ...

Astronomers have identified a rocky planet orbiting beyond two gas giants in the LHS 1903 system, a discovery that defies established planetary formation theories. Detected through ESA’s CHEOPS ...

What can rocky planets orbiting in the outer parts of a solar system teach scientists about planetary formation and evolution? This is what a recent study published in Science hopes to address as a ...

An artist's impression shows the "inside out" planetary system around the star LHS 1903. - ESA An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, ...

Scientists confirmed that an exoplanet mirrors its star’s chemical makeup, validating a core assumption about how planets ...

Astronomers have found a planet-forming disk that looks like a solar system on steroids. New images from NASA's Hubble Space Telescope have revealed an enormous, oddly shaped disk of gas and dust ...
