Scientists studying one of the earliest known galaxies using the James Webb Space Telescope have found that the universe's Era of Reionization may have occurred much earlier than previously thought.

"I was astonished by the unexpected results because they opened a new view on the first phases of galaxy evolution," Stefano Carniani, an astronomer at the Scuola Normale Superiore of Pisa in ...

Uncover the insights gained from the Webb telescope about early galaxies and their role in illuminating the universe.

The Big Wheel galaxy formed just 1.7 billion years after the Big Bang, at a time when the universe was only 15% of its current age.

But it's not just its age that makes this galaxy special. According to data published today in Nature, the galaxy heralds the start of the "cosmic dawn", when light from the first stars shone ...

JADES-GS-z14-0, the farthest known galaxy, has oxygen, a heavier element than scientists would expect to find just 300 million years after the Big Bang.

JADES-GS-z14-0 is the most distant confirmed galaxy ever found. New observations from 2 different teams of astronomers shows that the galaxy has oxygen, making scientists rethink (again!) how galaxies ...
