Astronomers have traced two mysterious fast radio bursts from space to wildly different places, which suggests the phenomenon ...

Around 2015, astronomers took on the painstaking task of stitching together Hubble Space Telescope images of this galaxy, but that effort had focused on the galaxy's northern half. Still, however, the ...

Early data of “little red dots,” or LRDs, from the James Webb Space Telescope (JWST) appeared to suggest the presence of ...

In February 2024, scientists on Earth detected a powerful radio blast from outer space. Seeking to discover where it had come ...

For the first time, astronomers have traced a fast radio burst (FRB)—an immensely powerful yet fleeting cosmic signal—to the outskirts of a massive elliptical galaxy located two billion light-years ...

High radiation during a time of frenzied star formation in the Milky Way left one stellar population with few chances to form planets, a study reports.

Using observations from 2017 and 2018, the Event Horizon Telescope (EHT) Collaboration has advanced our understanding of the ...

"The Hubble tension is now a Hubble crisis." The mystery of the Hubble tension has deepened with the startling finding that ...

This rare quasar with spiral arms could help astronomers understand how supermassive black holes feed and grow.

Astronomers compile a large sample of an unusual class of objects in an effort to connect the dots to the early universe.

Astronomers previously thought all FRBs were generated by magnetars formed through the explosions of very young, massive ...
