Two years of data from NASA's James Webb Space Telescope have now validated the Hubble Space Telescope's earlier finding that the rate of the universe's expansion ... range of cosmic time is ...

Scientists are challenging the existence of dark energy with a new model called "timescape," which suggests the Universe's ...

This alternative theory negates the concept of dark energy, stating instead that the observed stretching is not due to cosmic expansion but rather to how we perceive the passage of time and how we ...

giving it the appearance of a cosmic eye gazing toward Earth. NASA says the imagery helps it to study star clusters and active star-forming regions far away from Earth. It’s believed the Hubble has ...

Dark energy has been modern physics’ most successful placeholder, a theoretical force invented to explain why galaxies seem to be racing away from each other at ever-increasing speeds. Now, after ...

Douglas Adams, The Hitchhiker's Guide to the Galaxy Observatories like the Hubble ... account for the cosmic microwave background and the change in the universe's rate of expansion.

New imagery has been released from NASA’s Hubble Space Telescope, which captured a photo of a spiral galaxy more than 76 million light-years away from Earth. The galaxy known to observers as NGC 2566 ...

Both the Hubble tension and the surprises revealed by DESI are difficult to resolve in models which use a simplified 100-year-old cosmic expansion law – Friedmann's equation. This assumes that, on ...

Instead, new evidence supports the 'timescape' model of cosmic expansion, which doesn’t have ... However, in 1998 the Hubble Space Telescope measured the distances between distant galaxies ...
