A closer look at the planets around a star called LHS 1903 may just flip our understanding of how planetary systems form.

A planetary system 116 light-years from Earth has a peculiar pattern. It could flip the script on how planets form, scientists say.

We know that our Solar System is not the blueprint for all planetary systems out there. There are gas giant planets orbiting ...

Astronomers have found a distant world that challenges planetary formation theory, with a rocky planet where gas giants should be.

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

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 ...

When we start talking about Earth's origin, there are many theories on the table that have been tossed around for years, with the Big Bang hypothesis often leading the charge. But thanks to the James ...

Astronomers have long thought solar systems follow a simple pattern similar to our own: small, rocky worlds orbit close to the Sun, while large gaseous planets sit further out. For decades, ...

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

The planets around a nearby star seem to be in the wrong order, hinting that they formed through a different mechanism than the familiar one by which most systems grow ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. Planetary scientists are split, oscillating between two main theories that explain the order in ...
