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 ...

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 this mosaic image stretching 340 light-years across, Webb’s Near-Infrared Camera (NIRCam) displays the Tarantula Nebula star-forming region in a new light, including tens of thousands of ...

For science-fiction enthusiasts, that’s a bit depressing. Space is big, and while the speed of light is incredibly fast to us ...

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 ...

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 ...
