Thanks to the discovery of thousands of exoplanets to date, we know that planets bigger than Earth but smaller than Neptune orbit most stars. Oddly, our sun lacks such a planet. That's been a source ...

The textbook picture of how planets form—serene, flat disks of cosmic dust—has just received a significant cosmic twist. New research, published in Astrophysical Journal Letters, is set to reshape ...

In the swirling clouds of gas and dust that surround newborn stars, planets begin to form. These planet-forming disks are rich with clues about how worlds like Earth come to be. Until now, scientists ...

Astronomers using ALMA have discovered that planet-forming discs are not flat and serene but subtly warped, reshaping our understanding of how planets form. These slight tilts, similar to those seen ...

How did a planet this big form around a star this small? An international team of astronomers, including researchers from the University of Liège and collaborators in UK, Chile, the USA, and Europe, ...

A groundbreaking super-puff planet discovery has revealed two giant exoplanets with densities below cotton candy, changing how scientists understand alien worlds. These Jupiter-sized planets show that ...
