Using NASA's planet-hunting spacecraft TESS (Transiting Exoplanet Survey Satellite), astronomers have discovered three ...

Astronomers are investigating a strange class of exoplanets known as eccentric warm Jupiters — massive gas giants that orbit ...

A new study led by UNLV scientists sheds light on how planets, including Earth, formed in our galaxy—and why the life and ...

Not all of the solar system’s building blocks formed simultaneously. Some of the first solid bodies, or planetesimals, formed ...

Researchers are studying eccentric warm Jupiters, giant exoplanets that follow odd, elongated orbits unlike anything in our solar system.

The James Webb Space Telescope may have found dozens of elusive brown dwarfs — strange objects larger than planets but smaller than stars — beyond the Milky Way for the first time ever.

JWST found a carbon-atmosphere planet orbiting a pulsar, challenging current models of how planets form. Scientific progress often comes from data that don’t fit our current understanding. This idea, ...

Astronomers have discovered a surprisingly "pristine" red giant with the lowest concentration of heavy elements ever seen in ...

"Our approach gives astronomers an idea of how many spots a star might have, where they are located, and how bright or dark they are." NASA scientists have devised a new way to use planets that cross, ...

Astronomers found an interstellar "tunnel" - a cosmic channel that connects our solar system to distant stars, according to a ...

Comet C/2025 A6 (Lemmon) is this year’s brightest comet visible from Earth—an icy relic from the solar system’s origins that ...
