New measurements of the rate of expansion of the universe, led by astronomers at the University of California, Davis, add to a growing mystery: Estimates of a fundamental constant made with different ...

For a generation, cosmologists have worked with a simple story: the universe is not only expanding, it is expanding faster ...

A cosmic camera hog is helping astronomers figure out the rate of the universe’s expansion. Images of the supernova Refsdal have popped up multiple times in the constellation Leo, thanks to light from ...

Something very strange is up with cosmology. In the last few decades, one big question has created a crisis in the field: How fast is the universe expanding? We know that the universe has been ...

Physicists have improved the accuracy of a technique that uses variable stars to measure distances in the universe, providing a new figure for its expansion rate. When you purchase through links on ...

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 ...

Whatever dark energy is, explanations for it have less wiggle room following a Hubble Space Telescope observation that has refined the measurement of the universe’s ...
