Billions of light years away in a remote part of the universe, two neutron stars – the ultradense remnants of dead stars – collided. The catastropic cosmic event sent light and particles, including a ...

A powerful "gamma-ray burst" has been seen exploding from merging neutron stars hidden within a previously unknown ...

A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of astronomers led by Penn State scientists. The burst, known ...

Astronomers studying deep space have likely discovered a rare and powerful cosmic event. A group of NASA missions has found evidence that two extremely dense stars collided inside a very small galaxy ...

Astronomer and Queen guitarist Brian May teams up with astrophysicist Derek Ward-Thompson to bring the cosmos to 3D.

The Sombrero Galaxy (Messier 104) is one of the most unique galaxies captured by NASA’s telescopes. It gets its name from its shape, which resembles a broad-rimmed Mexican hat when viewed from Earth.

Two space telescopes really are better than one. This month NASA released a new image that combines observations from the James Webb Space Telescope (JWST) and the Chandra X-ray Observatory of two ...

Understanding how galaxies grow has long stood as one of astronomy’s core challenges. Over time, scientists have gathered evidence that galaxy mergers matter. When two galaxies move close, gravity can ...

Nearly all stars are found inside or around galaxies, because that's where the conditions are right for stars to form. Within galaxies, stars form inside cold, dense molecular gas clouds like those ...

Looking ahead: Future Euclid observations will enable scientists to watch how galaxy collisions spark bursts of star formation, fuel shrouded black holes, and unleash energetic feedback. According to ...

A selection of active galaxies with supermassive black holes at their centers, illustrating the variety of shapes that can result from the activity of black holes and their interaction with the ...

The pseudo-color images of JWST’s Quintet at redshift 6.71. a) The pseudocolor image created from NIRCam F115W (blue), F150W (green), and F200W (red) images. The five emission line galaxies in JWST’s ...
