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

The new study focuses on the Coma Cluster, one of our nearest massive galaxy clusters, serving as a crucial calibration point ...

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 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 ...

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

The Universe is expanding faster than ever, and recent findings fuel the ongoing debate among cosmologists. For decades, scientists have been trying to measure the rate at which the Universe is ...

This artist's impression of the 'quenching' process shows how a normal blue (star-forming) galaxy lost its gas while falling into the Coma Cluster very early on in its formation. Disclaimer ...

In contrast, the newly discovered protocluster “MAGAZ3NE J095924+022537” contains a high fraction of red and dead galaxies like the nearby “Coma” cluster (right). The discovery of an ...

Controversial new findings have reignited the longstanding cosmological quarrel involving what astronomers call the "Hubble ...
