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

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 ...

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 ...

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

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

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 ...

A team of Pennsylvania State University researchers has a unique take on mysterious red dots first observed by the James Webb ...

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 ...

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

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.

In 1925, Edwin Hubble's observation of Cepheid variables in the Andromeda galaxy revolutionized astronomy, proving the ...

Ten years ago, scientists heard the universe rumble for the first time. That first discovery of gravitational waves proved a ...
