Far beyond the reach of any spacecraft, a distant world glows with heat so intense that rock itself turns to vapor. In that ...

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

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

We know that our Solar System is not the blueprint for all planetary systems out there. There are gas giant planets orbiting closer to their stars than Mercury, and rocky worlds much larger than Earth ...

Stars and their planets form when large molecular clouds collapse in on themselves. Gravity pulls the dust and gas into a violent spiral, which flattens out into a structure known as a protoplanetary ...

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 ...

Classifying things in science is always fraught with the potential for uncertainty. Even things that are obviously different, ...

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, ...

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, ...

This month's NASA/ESA/CSA James Webb Space Telescope Picture of the Month offers us a two-for-one on brand new stars—with ...

Astronomers have long been puzzled by a cosmic mystery: planets orbiting two stars—like Star Wars’ Tatooine—are surprisingly rare, even though they should be common. New research suggests the culprit ...
