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 ...

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

A Rutgers-led team of scientists has uncovered evidence of how galaxies expand by tracing the invisible scaffolding of the ...

Gravitational waves can be described as ripples in the fabric of space-time, generated by the acceleration of massive objects. These waves travel at the speed of light and are often produced during ...

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

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 ...

Pfalzner's models show that interstellar objects — bodies ejected from other star systems — could be captured by these planet ...

Research team includes astrophysicists, computer scientists, artists, and philosophers from UC Riverside, USC, and Carnegie ...

Is there a scientific reason why the universe exists? In other words, what is the science of why there is anything at all, ...

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.

If you think a galaxy is big, compare it to the size of the universe: it's just a tiny dot which, together with a huge number ...

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