Two barred spiral galaxies, known as NGC 7733 and NGC 7734, are in the process of merging. The lower galaxy has a dusty knot atop its upper arm, which marks a third galactic companion. | Credit: ...

Galaxies like our Milky Way grew through cascading mergers of smaller galaxies that began billions of years ago. The ancient ...

The universe may be a little darker after a recent discovery has shown that there could be fewer galaxies populating it. A previous measurement by Hubble Space Telescope suggested there were 2 ...

The researchers also used computer simulations, or models, to understand how the galaxies are shaped. Gibson noted that galaxies can come in many shapes and sizes, from Frisbee-like disks to football ...

In the early Universe, long before they should have had time to grow, astronomers have found what they're calling 'red monsters': three large galaxies, almost as big as the Milky Way. It's a ...

Dozens of dwarf galaxies swarming around the Andromeda Galaxy like bees have been caught on camera by the Hubble Space Telescope, which took more than a thousand orbits of the Earth to take enough ...

A galaxy that has remained unchanged for 7 billion years — a rarity in the universe — has been observed by astronomers, offering a glimpse into cosmic history and adding to an enigmatic collection of ...

Our understanding of the universe begins with the Big Bang, a moment in time where the universe began expanding into what we see around us now. Big Bang nucleosynthesis describes how only the lightest ...

When the James Webb Space Telescope (JWST) began operations, one of its earliest surveys was of galaxies that existed during the very early universe. In December 2022, these observations revealed ...

A collection of Ultra-red Fattened Objects (UFOs) as seen by the James Webb Space Teescope. In a new study, a team of astrophysicists led by the University of Colorado Boulder has set out to unravel ...
