Large galaxies, like the Milky Way, attract smaller galaxies. Our solar system 's cosmic neighborhood spans 100,000 ...

The other large galaxies are the Andromeda Galaxy, and Messier 33 (the 33rd entry in Charles Messier's catalog of fuzzy things in the sky). Also in the Local Group are a couple dozen dwarf galaxies.

The Local Group is a small cluster of galaxies that includes the Milky Way. At least half of all galaxies in the Universe are thought to belong to similar groups. This authoritative volume provides a ...

The DESI survey reveals that active black holes in small galaxies are common. The findings may help reveal how the two cosmic bodies evolve together.

Caption Description: Gas in the EAGLE Simulation, showing hot bubbles (red colors) surrounding large galaxies, connected by colder filaments (blue and green colors). Inserts zoom in on the Local ...

Infrared astronomy has revealed so much about the universe, ranging from protoplanetary disks and nebulae to brown dwarfs, ...

Using the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), Chinese astronomers have identified nearly 300 ...

A similar galaxy interaction might have occurred in the Local Group in the past, which could explain the distribution of dwarf galaxies in co-rotating planes.

The Milky Way's system of small, orbiting satellite galaxies is quite unusual, a new 12-year study of other galaxies in the local universe has found. The Satellites Around Galactic Analogs (SAGA ...

It is believed that Dwarf galaxies are the first that formed, many of them merging afterwards to form bigger galaxies like the Milky Way, with the process leaving behind tidal debris such as GCs ...

Galaxies - the Milky Way's siblings - offer a surprising variety of forms and colours. Displaying symmetrical spiral arms, glowing red nebulae or diffuse halos, even the image of a galaxy can reveal ...
