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 ...

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

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

"The large volume of data from Rubin will give us a sample of all kinds of Type Ia supernovas at a range of distances and in ...

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

Knowing this relationship with confidence is helpful in making similar calculations on further points in space, effectively forming a ladder of measurements stretching ever further into the retreating ...

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 ...

"The DESI collaboration did the really hard part, their ladder was missing the first rung," says Scolnic ... a speed of 76.5 kilometers per second per megaparsec – not too far off similar cosmic ...

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.

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 ...
