The most distant galaxies in this deep field image from the James Webb Space Telescope appear as small, faint dots—and are receding from us faster than the speed of light due to cosmic expansion. If ...

This NASA/ESA Hubble Space Telescope image features the spiral galaxy Messier 77, also known as the Squid Galaxy. Everything on Earth, in our solar system, our galaxy, and beyond is contained within ...

In recent years, one of the most troubling puzzles in astrophysics has grown more urgent. Scientists have realized that the universe seems to be expanding faster than expected, throwing a wrench into ...

Some things we see in space appear to outpace light. Now we are learning to harness these bizarre optical illusions to ...

A more precise distance to the Coma galaxy cluster was measured. This measurement increases the discrepancy between observed and predicted universe expansion rates. The discrepancy, called the Hubble ...

A new Utah Valley University study is providing new evidence in a debate astronomers across the world haven’t been able to agree on — how fast the universe is expanding. The findings may add more fuel ...

Hubble’s updated view of NGC 3370, richer in light and detail than ever before, deepens our understanding of both the galaxy and the cosmos itself. This new Hubble Picture of the Week highlights a ...

Most explanations rely on "dark energy" to explain the Universe's accelerating expansion rate, but a new study takes a different path.

The universe is poised to die much faster than previously thought, according to new research by Dutch scientists. But there's no great need to panic. We still have 10 to the power of 78 years before ...

The expiration date for the universe is now sooner than experts previously thought, new research suggests. But don't cancel your summer vacation, because it's still trillions of years in the future.
