Astronomers have used the James Webb Space Telescope (JWST) to discover that a distant "hot Jupiter" planet has two ...

Using data from the eROSITA All-Sky Survey, astronomers have created a 3D map of the low-density bubble of X-ray-emitting, million-degree hot gas that surrounds the solar system. The investigation has ...

In a new study published in The Astrophysical Journal, a group of researchers from the University of Colorado Boulder ...

Hot spots and tunnels to neighboring "superbubbles" seem to have been created by supernovas and infant star outbursts. When you purchase through links on our site, we may earn an affiliate commission.

Discovery: On July 2, 2025, astronomers confirmed Comet 3I/ATLAS, marking only the third interstellar object (ISO) ever detected passing through our Solar System, after 1I/ʻOumuamua (2017) and ...

The 17-hour X-ray study, performed in late November 2025, captured a subtle X-ray glow emanating from 3I/ATLAS's core.

At the farthest reach of the Sun’s influence, NASA’s Voyager 1 spacecraft has stumbled into a region that behaves less like ...

The workings of our solar system are roughly the same now as they have been for millions of years. Moons circle their planets, the planets circle the sun, the sun’s magnetic fields and sunspots wax ...

Theia, the world that helped form the Moon, came from the Solar System. Chemical clues in Earth and Moon rocks reveal this close origin.

There’s a bit of a paradox about our galaxy: it’s both jam-packed with stars and cavernously empty. The Milky Way is crowded in the sense that it holds hundreds of billions of stars, as well as ...

This story sounds wild—even incredible. Black holes! Dark matter! Jostling planets! Yet the scenario is plausible—and testable soon. Black holes the size of an atom that contain the mass of an ...
