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

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

New research using the James Webb Space Telescope offers the most detailed portrait yet of how auroras form on Uranus.

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

The newborn planetary system appears to be emerging 1,300 light-years away around a baby star known as HOPS-315. Planet-forming materials were first identified using NASA's James Webb Space Telescope.

Deep within the Kuiper belt, some small worlds look like they were assembled from two mismatched snowballs pressed together.

For the first time in human history, we're watching a new solar system come to life. Not in theory, but in real, observable detail. NASA's James Webb Space Telescope (JWST) and its incredible ...

This is HOPS-315, a baby star where astronomers have observed evidence for the earliest stages of planet formation. The image was taken with the Atacama Large Millimeter/submillimeter Array (ALMA). In ...
