Astronomers studying FCC 224, an ultra-diffuse galaxy, have discovered luminous, overmassive globular clusters, providing key ...

New measurements reveal the Coma Cluster is 38 million light-years closer, worsening the Hubble tension crisis and challenging cosmology models.

AS Martin Griffiths lay in his hospital bed in an induced coma, his family and friends thought: “This is it.” All 21 of them ...

The universe's rapid expansion baffles scientists, with conflicting Hubble constant measurements hinting at new physics or ...

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

Data from the Dark Energy Spectroscopic Instrument had been used in a previous study to measure the relationship between the ...

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

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.

The new study focuses on the Coma Cluster, one of our nearest massive galaxy clusters, serving as a crucial calibration point for measuring cosmic distances. When the Dark Energy Spectroscopic ...

Scolnic recognized that this ladder could be anchored closer to Earth with a more precise distance to the Coma Cluster, one of the galaxy clusters nearest to us. "The DESI collaboration did the ...
