A recent study has uncovered a dramatic interaction between a planet and its parent star that is reshaping our understanding ...

The team found that the planet, dubbed HIP 67522 b, orbits its parent star so tightly that it appears to cause frequent ...

Long theorized but never observed, the first known “planet with a death wish” is described by Ilin and her colleagues in a ...

Stars often whip their planets with solar winds and radiation, pull them ever closer with gravity and sear them with heat.

Astronomers using the European Space Agency's Cheops mission have caught an exoplanet that seems to be triggering flares of ...

The clingy planet orbits so close to its star, it triggers powerful explosions of radiation that eat away at its atmosphere.

However, all is not lost. Their ultra-accurate simulations of the gravity field offer guidance toward a new mathematical foundation of gravity modelling. An upgraded simulator, which accounts for ...

What can Earth-sized exoplanets teach scientists about the formation and evolution of exoplanets throughout the cosmos? This is what a study recently posted to the arXiv preprint server hopes to ...

Astronomers confirm TOI-5573 b, a rare, miniature Saturn-like planet orbiting a small star, challenging theories of planetary ...

Radar and gravity records from NASA’s Magellan orbiter show that Venus' surface is still shifting and is not geologically ...

The planets fuse together, increasing their density and then stabilizing in non-resonant orbits. This process generates two very distinct populations of Sub-Neptunes: dense and less dense.

Astronomers may have finally figured out why a distant exoplanet with the density of a microwaved marshmallow has such a fluffy atmosphere. The planet, named WASP-107 b, is a gas giant situated ...
