The Hubble Space Telescope has unveiled a detailed look at the Crab Nebula, revisiting it after 25 years to track its rapid ...

The most precise measurement yet of how fast the Universe is expanding shows we have a real and serious problem on our hands.

Nearly a millennium ago, astronomers witnessed a brilliant new star blazing in the sky—a supernova so bright it was visible ...

To turn that distance into a Hubble constant, you also need the event’s redshift, which is tied to how fast the source is receding due to cosmic expansion. Standard approaches get the redshift by ...

The most precise measurement yet shows the Universe is expanding faster than expected, deepening the Hubble tension. The ...

Using a new framework, astronomers arrived at the most precise measurement of our universe’s expansion rate—but things still don’t add up, they say. Reading time 3 minutes One major, unsolved problem ...
