A new emulator is tackling the near-impossible task of mapping the universe's large-scale structure without sacrificing ...

When the "little red dots" were first discovered in 2022, scientists thought the objects might be galaxies as mature as the Milky Way, which is about 13.6 billion years old. That's because galaxies ...

Astronomers using the Webb Telescope may have found a new type of object: cold, glowing black hole stars from the early ...

Pfalzner's models show that interstellar objects — bodies ejected from other star systems — could be captured by these planet-forming disks. These objects could "seed" the disks, sweeping past the ...

Astronomers at Penn State have nicknamed the objects “universe breakers,” which may be unusual black hole atmospheres and could represent a missing link in the fast growth of supermassive black holes.

There’s a point in the universe where no light, no signal, and no matter can reach us — or so we thought. Galaxy clusters are ...

For the past decade, gravitational wave astronomy has opened our eyes to amazing cosmic phenomena thanks to LIGO, the Laser ...

The arrival of 'Oumuamua' in the solar system in 2017 sparked intense debate within the scientific community. This cigar-shaped mysterious object zoomed past at a speed of 26 kilometers per second, ...

The interactive online map, created using data from NASA's James Webb Space Telescope, details some 800,000 galaxies across a vast cosmic distance. Scrolling and zooming in can take users some 13.5 ...

Astronomers use many methods to determine this number, including gravitational lensing, the universe’s expansion rate, and more.

So what does the edge of the universe look like? Initially, I thought it might be like Earth's atmosphere, with a vacuum outside. But then I learned that's not the case at all. A ...

Tiny red objects spotted by NASA's James Webb Space Telescope (JWST) are offering scientists new insights into the origins of ...
