The Hubble tension—a disagreement over the universe's expansion rate—has led to fears of a cosmology crisis, but is it actually that serious? Reading time 8 minutes With consistent, impressive leaps ...

Astronomers have used the ages of more than 155,000 stars in the Milky Way to independently estimate the age of the universe, ...

The universe is expanding faster today than early cosmic measurements appear to allow. A proposed reversal in dark energy ...

Last time I wrote about new data that overturns the standard cosmological model. Before anyone starts dusting off their fringe cosmological models, we should note what this new study doesn't overturn.

NASA’s Hubble space telescope is running out of time. The aging observatory is slowly being dragged down toward Earth and is estimated to reenter through the atmosphere by 2033. NASA could save it, ...

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 ...
