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 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 ...

The first images from the Vera C. Rubin Observatory showed off a breathtaking preview of its capabilities — capturing millions of stars and galaxies light-years from Earth, along with thousands of ...

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 ...

Give them a constellation prize. A group of international scientists discovered three ultra-massive “Red Monster” galaxies capable of forming their own stars faster than the average nebula. The ...

Astronomers use telescopes to look back in time and observe stars and galaxies as they were millions and billions of years ...

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 ...

The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data are not confirming ...

Astronomers using the James Webb Space Telescope have discovered a rare jellyfish galaxy 8.5 billion light-years from Earth, ...

A NASA space telescope on a mission to map millions of galaxies has turned on its detectors for the first time, capturing images of tens of thousands of stars and galaxies. The SPHEREx, which is short ...

This video explores the enigma of dark matter, an elusive substance believed to make up most of the universe's matter. While the universe is populated by visible stars and galaxies, much of its mass ...
