The earliest galaxies are thought to have formed as the gravitational pull of dark matter, which has been impossible to study directly, slowly drew in enough hydrogen and helium to ignite stars.

The two galaxies spotted by NASA’s James Webb Space Telescope date to just 300 million to 400 million years after the Big Bang. They are unusually bright and suggest that the universe formed ...

Even though these monstrous galaxies are bursting at the seams with bright stars, astronomers didn’t even know they existed until relatively recently because the visible light that’s being ...

Four galaxies examined by the Hubble telescope date to a mere 500 million years after the big bang, but are so bright they offer scientists a new window into that early stage of the universe.

Ever since they were discovered about two decades ago, submillmetre galaxies or SMGs have fascinated astronomers. They are the brightest galaxies in the universe, forming about 2 billion years ...

The JWST has done it again. The powerful space telescope has already revealed the presence of bright galaxies only several hundred million years after the Big Bang. Now, it's sensed light from a ...

Using data from the James Webb Space Telescope, astronomers have discovered dormant galaxies with a wide range of masses in ...

These 135 galaxies were particularly bright in two wavelengths of infrared light, which was created by radiation mingling with galactic gases like hydrogen and oxygen, according to a statement ...

The James Webb Space Telescope could target tiny and bright galaxies in the early universe to unveil some secrets about the universe's most mysterious stuff, dark matter.

The intense gravity from extra-bright galaxies with huge black holes at their cores is bending light to create cosmic magnifying glasses, astronomers say. IE 11 is not supported.

A composite of Stephan’s Quintet, a visual grouping of five galaxies, constructed from almost 1,000 separate image files from the James Webb Space Telescope. UCLA astrophysicists believe if cold ...
