To measure this expansion, scientists use a cosmic distance ladder. This method relies on celestial objects, such as Type Ia supernovae, to estimate distances in the universe. Scolnic's team used data ...

"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.

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 ...

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 ...

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

the team was then able to recalibrate the so-called cosmic distance ladder and arrived at a value of 76.5 km/sec/Mpc for the so-called Hubble constant. This is once again considerably higher than ...

of distance. However, when they calculate the expansion rate using observations of the cosmic microwave background — the afterglow of the Big Bang — along with our standard model of physics ...

To measure the Hubble constant, he described the cosmic distance ladder, from parallax measurements to "Type Ia supernovae". He addressed the unresolved "Hubble tension," where three methods yield ...
