Astronomers studying the Milky Way's oldest stars have estimated that the Universe is about 13.6 billion years old.

A rare gravitationally lensed supernova called SN 2025wny appears in five separate images due to the gravity of two ...

The Vera C. Rubin Observatory has started releasing its first discoveries: including supernovae, variable stars and asteroids ...

An extraordinarily rare, gravitationally lensed supernova may offer a powerful new way to measure the universe’s expansion rate.

Instead of focusing on how fast the universe is expanding, they looked at the ages of some of the oldest stars in our galaxy.

Researchers from the University of Bologna and the Leibniz Institute for Astrophysics Potsdam (AIP) along with other institutes have proposed a new way to address the Hubble tension by comparing ...

A burst of light in the deep sky is doing something it should not be able to do. It looks like one supernova, but it shows up ...

A new study has estimated the universe’s possible age by using precise data on stars.

The universe's expansion may actually have started to slow rather than accelerating at an ever-increasing rate as previously thought, a new study suggests. "Remarkable" findings published today in ...

The universe’s expansion might not be accelerating but slowing down, a new study suggests. If confirmed, the finding would upend decades of established astronomical assumptions and rewrite our ...

We could go out with a crunch, and not a bang. Contrary to popular belief, our universe may not be constantly expanding after all. A groundbreaking study by South Korean researchers suggests that dark ...
