The Antennae Galaxies (also known as NGC 4038/NGC 4039 or Caldwell 60/Caldwell 61) are a pair of interacting galaxies in the constellation Corvus. Centaurus A (also known as NGC 5128 or Caldwell 77) ...

Space scientists have witnessed a collision of five galaxies at an astonishing speed of two million miles per hour. The dramatic event was observed in Stephan's Quintet, a nearby galaxy group ...

What Happens When Galaxies Collide? In about four billion years from now, the Milky Way and Andromeda galaxies will crash together Visualization: NASA, ESA, and F. Summers, STScI Simulation credit ...

The Pinwheel Galaxy lies 21 million light-years away in the Ursa Major constellation. The Antennae Galaxies are rich in black holes and neutron stars, driving rapid star formation and evolution.

"Our measurements imply that the supermassive black hole mass is 10% of the stellar mass in the galaxies we studied." Using the James Webb Space Telescope (JWST), astronomers have discovered ...

Ring galaxies are some of the rarest galaxies found throughout our universe, and for years scientists have scratched their heads, trying to figure out exactly how these galaxies came to be.

Ultra-faint dwarf galaxies are the faintest type of galaxy in the universe. Typically containing just a few hundred to a thousand stars—compared with the hundreds of billions that make up the ...

Astronomers have studied three ultra-faint dwarf galaxies using data from the DESI Legacy Imaging Surveys and the Gemini South telescope. These galaxies, located near the spiral galaxy NGC 300, exist ...

Gravitational waves are unlocking the origins of black holes, linking spin shifts to sequential mergers in star clusters.
