Wormholes are often imagined as tunnels through space or time — shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen. In ...

A massive analysis of 2,884 exploding stars has uncovered new evidence that dark energy, the mysterious force accelerating ...

Basic Knowledge Episode 1Starting this week, every Thursday we will present a series called "Universe from Zero," where we ...

The two keys to Edwin Hubble 's breakthrough discovery were forged by others in the 1910s. The first key, the period-luminosity scale discovered by Henrietta Leavitt, allowed astronomers to calculate ...

When you look at the 'bell-shaped' or 'funnel-shaped' chronological illustrations (diagrams) of the history of the universe ...

Mathematicians have uncovered what they argue is a fundamental flaw in the standard model of the universe, potentially challenging the need for dark energy. Their calculations suggest that the ...

The universe is expanding 'too fast', a study has warned – and scientists have no idea why. An international team of astronomers have carried out some of the most precise measurements yet of how ...

A novel theory suggests that the current expansion rate of the universe is not fixed, but was in fact quite different in the early universe—and that the universe could start contracting at some point.

Astronomers have tried to measure the expansion rate of the universe using two fundamentally different approaches. One method relies on measuring distances to stars and galaxies in the nearby universe ...

Douglas Adams told us the answer to life, the universe and everything is 42. If only cosmology were so straightforward. Astronomers have been arguing for years about a number every bit as fundamental, ...

Newswise — Astronomers have sought to measure the expansion rate of the Universe using two fundamentally different approaches. One method relies on measuring distances to stars and galaxies in the ...
