Astronomers have created the largest and most detailed 3D map yet of a glowing signal from the early universe, revealing hidden galaxies and gas from 9-11 billion years ago. By analyzing faint ...

The space between galaxies is not empty. In a new map of the early universe, those “blank” stretches take on a faint, ...

The oldest stars in the Milky Way are forcing a fresh look at one of cosmology’s biggest arguments. If some of them are about 13.

Astronomers have unveiled one of the most ambitious maps yet of the early universe, revealing a vast "sea of light" between ...

Researchers from the University of Bologna and the Leibniz Institute for Astrophysics Potsdam (AIP) along with other institutes have proposed a new way to address the Hubble tension by comparing ...

A sweeping new ALMA image has peeled back the veil on the Milky Way’s core, exposing a dense network of cold gas filaments ...

When most people think of a supernova, they're thinking of a Type II core-collapse supernova. These are massive stars that have reached the end of their time on the main sequence. They've used up ...

University of Oregon astronomer Yvette Cendes made a surprising discovery years after a black hole shredded a star. What is "Jetty McJetface"?

Astronomers produced the most complete map of the center of the Milky Way, which can provide insight into how stars and planets are formed.

Researchers explore Dyson spheres around red dwarf stars, detailing infrared signatures, equilibrium temperatures, and potential candidates for observation using modern telescopes.

New studies reveal how metallicity and stellar evolution determine whether massive stars expand into red supergiants prior to Type II supernova explosions.

A new study shows that, not only did the agency’s 2022 DART mission shift the orbit of the moonlet Dimorphos, it also changed the path of its parent asteroid around the sun.
