Galaxy clusters -- the big cities of the universe -- are home to many giant elliptical galaxies that have completed their growth and are not forming stars. However, it is still unclear what has shut ...

Early models of galaxy formation painted a relatively orderly picture. A few hundred million years after the Big Bang, small spiral galaxies formed through the gravitational collapse of hydrogen and ...

Researchers have used the ALMA telescope and found old elliptical galaxies in the universe can form from intense star formation within early galaxy cores. An international team of researchers ...

The "afterglow" of the universe is an important piece of evidence for the Big Bang. This background radiation also provides important answers to the question of how the first galaxies were able to ...

Astronomers have identified what appears to be an unusually distant candidate “jellyfish” galaxy, a strange object trailing a one-sided tail of newborn stars that appears consistent with ram-pressure ...

These three galaxy images from the AEGIS survey show a range of galaxy types: a disk-like spiral galaxy (top), a cloud-like elliptical galaxy (middle), and an irregular galaxy resulting from a ...

A team of astronomers from the University of Geneva used the James Webb Space Telescope (JWST) to spot the most distant quiescent galaxy ever found. The discovery, made just 700 million years after ...

Schematic diagram shows how spheroid formation occurs in distant submillimetre-bright galaxies, and how this process connects to the evolution of giant elliptical galaxies in today's Universe. On the ...

Researchers suggest the universe's background radiation has been overestimated, potentially challenging the standard model of cosmology and our understanding of early galaxy formation. Space, time and ...
