Early galaxies were star-forming machines, furiously gobbling up gas and spitting out stars. A new model helps explain why ...

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 ...

Using the James Webb Space Telescope, scientists spotted thin and thick disks in galaxies as far back as 10 billion years ago—something never seen before. These observations reveal that galaxies first ...

The standard cosmological model (present-day version of "Big Bang," called Lambda-CDM) gives an age of the universe close to 13.8 billion years and much younger when we explore the universe at ...

New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite galaxies—up to 100 more than we currently know. These elusive "orphan" galaxies have ...

Two colliding galaxies have been found to be reorganizing their dwarf satellites, potentially solving a major conundrum plaguing the standard model of cosmology. When you purchase through links on our ...

Astronomers using NASA’s James Webb Space Telescope have stumbled upon a puzzling population of galaxies that look far too bright for their age. In four patches of sky, covering more than 500 square ...

Using the James Webb Space Telescope and the Atacama Large Millimeter/sub-millimeter Array , astronomers have investigated 70 dusty, star-forming galaxies at the very edge of the universe. These ...

The largest 3D map of the universe, created based on data from the Dark Energy Spectroscopic Instrument, shows 47 million galaxies in stunning detail.
