Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky ...

A small red dwarf star in the Milky Way has drawn attention after astronomers mapped four closely orbiting planets around it.

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.

Astronomers say a newly discovered solar system about 116 light years from Earth is challenging long held ideas about how planets form.According to CNN, researchers using telescopes from NASA ...

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 ...

A young star called V1298 Tau is giving astronomers a front-row seat to the birth of the galaxy’s most common planets. Four massive but extremely low-density worlds orbiting the star appear to be ...
