The Vera C. Rubin Observatory is set to revolutionize our understanding of the cosmos by detecting millions of exploding ...

When scientists measure this expansion rate (known as the Hubble constant) using nearby objects, they consistently get a higher value than when they measure it using light from the early universe.

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 is expanding much faster than scientists predicted ... both far into the distance and far into the past, since light travels at a constant speed. When we look at the sun, for example ...
