In around 5 billion years, the sun will run out of the fuel needed for nuclear fusion in its core. This will cause its inner core to collapse under the force of the sun's own gravity. At this point, ...

AUSTIN, Texas — An international team of astronomers led by Fritz Benedict and Barbara McArthur of The University of Texas at Austin has used Hubble Space Telescope to solve one of the biggest ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Pasadena, CA — Ohio State University researchers have found a way to measure distances to objects three times farther away in outer space than previously possible, by extending a common measurement ...

The universe’s expansion rate was supposed to be a solved problem, yet the latest high precision map of the early cosmos has pushed one of modern astronomy’s sharpest conflicts back to center stage.

Astronomers have taken a hard new look at how fast the universe is expanding and arrived at a disquieting conclusion. The latest observations from the James Webb Space Telescope and the Hubble Space ...

The cosmic distance ladder is the world’s longest ruler, built to measure the universe. Since the time of the ancient Greeks, scientists have been constructing a cosmic measuring tape to measure the ...

A new measurement confirms what previous — and highly debated — results had shown: The Universe is expanding faster than predicted by theoretical models, and faster than can be explained by our ...

It’s a bit mind-bending to realise that everything we know about the scale of the universe comes from people stuck on a tiny rock, peering through glass at dots of light. We can’t exactly pull out a ...
