Astronomers studying a dim red dwarf star called LHS 1903 have found a four-planet system with an architecture that defies the standard rules of how rocky worlds take shape. The outermost planet in ...

NEW YORK (CNN) — An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers who discovered it using telescopes from NASA and the ...

The James Webb Space Telescope (JWST) captures extraordinary images of two planet-forming discs. For the first time, scientists have witnessed these cosmic structures from a unique perspective, ...

Researchers said the findings may also help scientists better understand how planets form around stars.

Far beyond the reach of any spacecraft, a distant world glows with heat so intense that rock itself turns to vapor. In that extreme environment, scientists have uncovered a rare clue about how planets ...

These images, taken with the European Southern Observatory's Very Large Telescope (VLT) shows a planetary system being born around the young star WISPIT 2. The star is surrounded by a disc of gas and ...

An international team of astronomers has discovered a distant planetary system that challenges long-standing theories of how planets form. Across our galaxy, astronomers routinely observe a ...

A strange “forbidden” planet spotted by the James Webb Space Telescope is turning planetary science on its head. TOI-5205 b, a Jupiter-sized world orbiting a small, cool star, has an atmosphere ...

When we think of asteroids, we almost immediately think of giant rocks bouncing around like the iconic chase scene in "The Empire Strikes Back," and we often hear how they are remnants from the birth ...

Kepler-51d is a giant, ultra-light “super-puff” planet wrapped in an unusually thick haze that’s blocking scientists from seeing what it’s made of. Observations from JWST revealed that this haze may ...
