The Hubble Space Telescope has been used to determine the mass of white dwarf star LAWD 37. It is "56 percent the mass of our ...

For years, scientists have worked to chart the universe’s massive structure, aiming to test key models of cosmology. These ...

Is the Hubble constant—a key part of how we measure the expansion of our universe—in a crisis? Some cosmologists say yes.

New measurements of the universe’s expansion using James Webb Space Telescope appear to resolve the Hubble constant conflict ...

The historic measurement allowed astronomers to derive an independent estimate of the Hubble constant. So far, that value slots right in between the Planck values and those derived from the cosmic ...

The Hubble constant, a set number that connects a galaxy’s speed to its distance from Earth and tells us how fast the ...

Freedman and her team will be using the Webb Telescope next year to get measurements in a group of galaxies called the Coma cluster, which should provide more data from a different angle, she said.

In 2014, Freedman brought her work to UChicago to further research how to increase the accuracy of Hubble constant measurements to determine whether something fundamental is missing from the modern ...

However, DESI's measurements of the Hubble constant in the modern universe, using the brightness of type Ia supernova explosions in galaxies, gives a value of 76 km/s/Mpc — still showing the ...

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 ...

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 ...

They ended up with a Hubble constant value of 72.6 km/s/Mpc, very close to Hubble's value of 72.8 km/s/Mpc. Now it's up to the theorists to come up with novel hypotheses to explain these findings.
