JWST finds spiral galaxy about 5 times more massive than Milky Way — scientists call it 'Big Wheel'

Scientists have uncovered a massive galaxy that existed just 2 billion years after the Big Bang. But how did this colossal "Big Wheel" form so early in the universe? The answer could change everything we know about galaxy growth.

Unknown physics may help dark energy act as 'antigravity' throughout the universe

Dark energy may have a completely unknown aspect of physics acting as an accomplice in its efforts to defy gravity, suppressing the growth of large-scale structures like galaxy superclusters.

Stephen Hawking's black hole theory has big implications for the shape of the universe, new study claims

Elusive black hole radiation predicted by Stephen Hawking may have influenced the way the universe took shape after the Big Bang, new research suggests.

'I was astonished': Ancient galaxy discovered by James Webb telescope contains the oldest oxygen scientists have ever seen

Scientists have made the record-breaking detection of oxygen in an ancient galaxy that existed just 300 million years after the Big Bang. The detection is prompting astronomers to rethink how quickly stars and galaxies formed in the young universe.

Universe grew ‘much faster than expected’ after Big Bang, astronomers say

The recent detection of oxygen in the most distant known galaxy is making astronomers rethink how quickly galaxies formed after the Big Bang.

Oxygen discovered in most distant galaxy ever seen: 'It is like finding an adolescent where you would only expect babies'

Astronomers have discovered oxygen and heavy elements in the earliest galaxy ever seen, suggesting some galaxies as early as 300 million years after the Big Bang matured early.

Cosmic dark energy may be weakening, astronomers say, raising questions about the fate of the universe

The universe has been expanding ever since the Big Bang almost 14 billion years ago, and astronomers believe a kind of invisible force called dark energy is making it accelerate faster.

You’ve heard of the Big Bang. Now astronomers have discovered the Big Wheel – here’s why it’s significant

Deep observations from the James Webb Space Telescope (JWST) have revealed an exceptionally large galaxy in the early universe. It’s a cosmic giant whose light has travelled over 12 billion years to reach us. We’ve dubbed it the Big Wheel, with our findings published today in Nature Astronomy.

Water in the universe may have formed closer to the Big Bang than previously thought

"We were surprised that water could actually form so early on — even before the birth of the first galaxies."

Space

The universe's water is billions of years older than scientists thought — and may be nearly as old as the Big Bang itself

A new study suggests that water first appeared in the universe just a couple hundred million years after the Big Bang — meaning life could have evolved billions of years earlier than previously thought.

1st supernovas may have flooded the early universe with water — making life possible just 100 million years after the Big Bang

A new study suggests that the explosive deaths of the universe's earliest stars created surprising quantities of water that may have sparked extraterrestrial life in the very first galaxies.

Feeding supermassive black holes may have ended the cosmic 'dark ages' billions of years ago

NASA's Chandra and NuSTAR telescopes have teamed up to study a supermassive black hole-powered quasar that could have played a key role in ending the cosmic dark ages.

'Dark photons' at Big Bang's cosmic dawn could shine a light on dark matter

Interactions between dark matter and dark photons during a "missing chapter" cosmic history could shed light on one of the most troubling cosmic mysteries.

New images show galaxy forming that is similar in mass to young Milky Way

Nasa’s James Webb Space Telescope has detected and ‘weighed’ a galaxy that existed about 600 million years after the big bang.

Could dark matter have been forged in a 'Dark Big Bang?'

The Big Bang may not have been the origin of the universe's most mysterious matter. Instead, dark matter could have been created in a second creation event, a "Dark Big Bang."

'The bottom line is, I told you so': JWST observations upend standard model of how galaxies form, new study claims

The James Webb Space Telescope's discovery of unusually bright and massive galaxies soon after the Big Bang has cast doubt on the standard model of galaxy evolution and bolstered a rival theory for how physics may work on large scales, according to a team of astronomers.

James Webb Space Telescope discovers mysterious 'red monster' galaxies so large they shouldn't exist

The James Webb telescope has spotted three gigantic "red monster" galaxies that were spawned soon after the Big Bang. They're so large they could rewrite the laws of galactic evolution.

Dark energy: could the mysterious force seen as constant actually vary over cosmic time?

As I finished my PhD in 1992, the universe was full of mystery – we didn’t even know exactly what it is made of. One could argue that cosmologists had made little progress in our understanding of these basic facts since the discovery of the cosmic microwave background (CMB), the…

The earliest galaxies formed amazingly fast after the Big Bang. Do they break the universe or change its age?

The James Webb Space Telescope (JWST) is the largest and most powerful space telescope built to date. Since it was launched in December 2021 it has provided groundbreaking insights. These include discovering the earliest and most distant known galaxies, which existed just 300 million years after the Big Bang.
