Astronomers have identified an unprecedented cosmic titan—a vast superstructure of galaxies stretching 1.3 billion ...

With a length of 428 megaparsecs, or around 1.39 billion light-years, the superstructure is the biggest ever spotted.

In the moments before the Big Bang, our universe was a hot, dense, and extremely high-energy place. That all changed when the universe exploded 13.8 billion years ago. Rapid inflation divided a ...

"This may be reshaping how we think about the Universe, and it's exciting! There are still surprises left in cosmology, and who knows what discoveries will come next?" This research was published in ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion. When you ...

What is the structure of our physical reality? Physicists have long imagined space and time interweaving into “space-time”, the metaphorical fabric that underlies the cosmos. But there may be ...

Dark matter can't be too heavy or it might break our best model of the universe, new research suggests. We have an abundance of evidence that something fishy is happening in the 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.

Extremely precise measurements of the distance between the Earth and the Coma cluster of galaxies provide new evidence for the Universe’s faster-than-expected rate of expansion. (Photo courtesy ...

The Hubble tension grows: new data shows the Universe’s expansion defies current physics models, suggesting our understanding of cosmology may need a major overhaul. Credit: SciTechDaily.com New ...

(Artist’s concept.) Credit: SciTechDaily.com Astronomers compile a large sample of an unusual class of objects in an effort to connect the dots to the early universe. Shortly after NASA’s James Webb ...
