Astronomers discovered Gomez’s Hamburger, a massive protoplanetary disk. Edge-on view shows dust and gas layers with clumps ...

At extreme pressures and temperatures, water becomes superionic — a solid that behaves partly like a liquid and conducts ...

A new theory could explain the origin and properties of systems of rocky super-Earths and their relationship with the terrestrial planets of the solar system. A new theory for how rocky planets form ...

(NewsNation) — In a development that might better explain how planets form around stars, astronomers have found that some stars might not have the right ingredients to make certain types of planets, ...

A new theory for how rocky planets form could explain the origin of so-called "super-Earths"—a class of exoplanets a few times more massive than the Earth that are the most abundant type of planet in ...

BLOOMINGTON, Ind. — A new theory of how planets form finds havens of stability amid violent turbulence in the swirling gas that surrounds a young star. These protected areas are where planets can ...

The original version of this story appeared in Quanta Magazine. When Galileo Galilei, a mathematician at the University of Padua, trained a spyglass of his own creation on the sky, he was overwhelmed ...

It takes a particular confluence of conditions for rocky planets like Earth to form, as not all stars in the universe are conducive to planet formation. Stars give off ultraviolet light, and the ...

Astronomers have developed the most realistic model to date of planet formation in binary star systems. The researchers, from the University of Cambridge and the Max Planck Institute for ...

Most planetary systems contain worlds larger than Earth but smaller than Neptune, and the low-density planets around one ...

"The combination of extreme disk size, strong asymmetries, winds, and potential planet formation makes it the perfect ...

Thanks to the discovery of thousands of exoplanets to date, we know that planets bigger than Earth but smaller than Neptune ...
