"The Hubble tension is now a Hubble crisis." The mystery of the Hubble tension has deepened with the startling finding that ...

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 ...

Through the lens of the Hubble and James Webb Space Telescopes, scientists are zeroing in on the Hubble Constant, a vital ...

astronomers can chain Cepheid readings into a "cosmic distance ladder" to peer deeper into the universe's past. But this is where the headache begins. Using the European Space Agency's Planck ...

Incompatible values are determined for the speed at which the universe expands. Now the mysterious discrepancy deepens.

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 ...
