"The Hubble tension is now a Hubble crisis." The mystery of the Hubble tension has deepened with the startling finding that the Coma Cluster of galaxies is 38 million light-years closer than it should ...

In the 1920s, astronomers thought that the Milky Way was the entire universe. Hubble's discovery revealed a much bigger ...

Hubble revealed a universe of galaxies that existed beyond ours — but he couldn't have done it without a little help.

Hubble’s high-resolution imagery allowed researchers to hone in on more of the Bullseye galaxy’s rings — and helped confirm ...

This was a relief to Edwin Hubble's contemporary, Albert Einstein, who deduced the universe could not remain stationary without imploding under gravity's pull. The rate of cosmic expansion is now ...

JWST measured the distances between stars and galaxies, which confirmed earlier measurements made by the Hubble Space Telescope. “The discrepancy between the observed expansion rate of the ...

Hubble's images have helped to pin down the age of the universe, which the expansion rate of pulsating stars suggests is some 13 billion to 14 billion years. Hubble has also captured images of ...

This discrepancy between model and data became known as the Hubble tension. Now, results provide even stronger support to the faster rate of expansion. A new measurement confirms what previous ...

And then astronomers like myself can go and measure the expansion of the universe today, and it doesn't match the prediction," Solnic added." Nobody understands the Hubble tension. When it comes ...
