Astronomers have created the largest and most detailed 3D map yet of a glowing signal from the early universe, revealing hidden galaxies and gas from 9-11 billion years ago. By analyzing faint ...

Astronomers have uncovered a hidden cosmic web of galaxies and gas by mapping hydrogen light from the early universe.

Hints of impossibly bright, massive objects in the infant universe have forced astronomers to rethink how the first cosmic structures formed. A growing group of researchers now argues that some of ...

An international team of astronomers has uncovered multiple evolutionary paths for the universe's most massive galaxies. Observations of ultramassive galaxies, each containing more than 100 billion ...

Alexey A Petrov receives funding from the US Department of Energy. Scientists working with the James Webb Space Telescope discovered three unusual astronomical objects in early 2025, which may be ...

The James Webb Space Telescope, launched in 2022, has discovered something that may shatter current theories about the universe's early development. The new result does not affect the big bang theory, ...

Primordial magnetic fields, billions of times weaker than a fridge magnet, may have left lasting imprints on the Universe. Researchers ran over 250,000 simulations to show how these fields shaped the ...

Add Yahoo as a preferred source to see more of our stories on Google. A developing galaxy cluster dating to about 1 billion years after the Big Bang is shown in this handout image released on January ...

A telescope in South America has found tantalizing evidence of primitive galaxies born in the early universe, a find that, if confirmed, would mark the first-ever view of the so-called "dark galaxies.

An international team of astronomers has achieved a first in probing the early universe, using the James Webb Space Telescope (JWST), detecting a supernova—the explosive death of a massive star—at an ...

In a first, scientists have recreated the formation of the first ever molecules in the universe to learn more about early star formation. When you purchase through links on our site, we may earn an ...
