The Hubble tension is one of the biggest mysteries in cosmology. It centers around the Hubble constant—the measurement of how fast our universe is expanding—which comes out as two different numbers ...

For decades, astronomers have been trying to nail down the value of the Hubble constant—a measure of how fast the universe is expanding. But some cosmologists say there’s evidence that the universe is ...

The two keys to Edwin Hubble's breakthrough discovery were forged by others in the 1910s. The first key, the period-luminosity scale discovered by Henrietta Leavitt, allowed astronomers to calculate ...

Our universe appears to be expanding about eight percent faster than initially assumed possible, according to new observations from the James Webb Space Telescope. There has been a long-established ...

The universe really seems to be expanding fast. Too fast, even. A new measurement confirms what previous—and highly debated—results had shown: The universe is expanding faster than predicted by ...
