A distant star system with four super-sized gas giants has revealed a surprise. Thanks to JWST’s powerful vision, astronomers detected sulfur in their atmospheres — a chemical clue that they formed ...

Astronomers have found a rocky planet where it should not exist, orbiting far from a cool red star. Could this strange ...

The discovery overturns traditional models that predicted gas giants in outer orbits and suggests planets can form in gas-poor environments.

Gas giants possibly developed slowly in the solar system. They developed cores layer by layer within a disk of ice and dust ...

A team of 48 astronomers from 14 countries, led by the University of Massachusetts Amherst, has discovered a population of ...

A newly studied solar system breaks the usual planet pattern, raising fresh questions about how rocky and gas planets form.

The mechanisms underlying two important phenomena in the Archean—the emergence of continental crust and the presence of an exceptionally strong geomagnetic field—remain poorly understood. Notably, ...

Astronomers have puzzled for decades over how massive elliptical galaxies appeared so early in cosmic history. The standard ...

Scientists have identified a rocky outer planet in a system where a gas giant was expected. The discovery challenges ...

Counter-intuitive finding suggests particle formation from natural and anthropogenic organic compounds might increase during extreme heat events ...

As of Wednesday afternoon, both primary global forecast models (GFS and ECMWF) were keeping this storm far enough offshore ...

Old crystals found in Western Australia are drawing fresh attention from geologists studying how the planet first took shape.
