"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 ...

Astronomers have been confounded by recent evidence that the universe expanded at different rates throughout its life. New findings risk turning the tension into a crisis, scientists say.

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

Using this high-precision measurement as a first rung, the team calibrated the rest of the cosmic distance ladder. They arrived at a value for the Hubble constant of 76.5 kilometers per second per ...

This uniformity means Type Ia supernovas are often referred to as "standard candles," serving as a vital rung on the "cosmic distance ladder." Usually, it is difficult to tell if an astronomical ...

asked Scolnic. So that its results are truly unbiased, DESI builds its own cosmic distance ladder from scratch, rather than relying on previous measurements, with one exception. This is why its ...
