The universe's first galaxies were hot messes, according to a recent study. During their younger days, they were wild, ...

For decades, scientists have puzzled over why galaxies spin faster than expected. The stars in their outer regions move so quickly that, by the laws of physics, they should fly apart. Something unseen ...

JWST observations suggest Population III stars may have formed 13 billion years ago, helping trace early galaxies.

Astronomers have uncovered a previously unknown, extreme kind of star factory by taking the temperature of a distant ...

What the researchers found, grimly, is that the universe has gotten gradually colder. Ten billion years ago, the average dust grain temperature in the sampled galaxies was warmer by about 10 degrees ...

The universe is expanding. That much is clearer. But it’s less clear whether this expansion is accelerating or slowing down. At the heart of this upheaval lies the cosmic yardstick astronomers have ...

Six ancient galaxies have been discovered which have “stunned” scientists. The galaxies, labelled “monsters” by scientists studying them, have stunned researchers who said they thought they had made ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. White diamond symbols mark the locations of 20 of the 83 newfound young, low-mass galaxies ...

Evidence suggests the universe’s expansion has started to slow, not accelerate. The results imply dark energy is weakening ...

Astrophysicists have produced the largest 3D map of our universe at a time when it was in just in its infancy. Light from distant stars and galaxies can take hundreds of millions to billions of years ...
