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 ...

We know the universe is and always was expanding, but we’ve never really known just how fast it’s happening. That is, until now. Researchers have used gravitational lensing to and watched a star die 5 ...

In the grand puzzle of the cosmos, one question continues to defy easy answers: how fast is the universe expanding? Astronomers have tried two main methods to figure it out, but their numbers don’t ...

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 ...

IT IS ONE of the biggest mysteries in cosmology—and getting bigger all the time. Ever since Edwin Hubble, an American astronomer, published observations of distant galaxies in 1929, scientists have ...

Scientists have known for decades that the universe is expanding, but research in the past few years has shaken up calculations on the speed of growth -- raising tricky questions about theories of the ...

The plot represents the new model with the x-axis and the y-axis showing the minimum sizes of collapsing and expanding regions that can impact cosmological measurements. The contours are independent ...

On human timescales, the universe may as well be eternal. It’ll be here long after our species and our planet are gone, but it does have an end. The generally accepted long-term evolution of the ...
