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

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.

Though groundbreaking, this data required additional refinement for higher precision. The big breakthrough happened when Scolnic and his team discovered that the cosmic distance ladder was missing an ...

Through the lens of the Hubble and James Webb Space Telescopes, scientists are zeroing in on the Hubble Constant, a vital ...

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

The universe appears to be expanding at a staggering speed, much faster than expected. A recent study reinforces this observation, confirming an expansion that contradicts current ...

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 ...

Hubble's discovery of expanding galaxies confirmed the universe's vastness, laying the foundation for the Big Bang theory and ...

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 ...

astronomers can chain Cepheid readings into a "cosmic distance ladder" to peer deeper into the universe's past. But this is where the headache begins. Using the European Space Agency's Planck ...
