Our little Local Group, by contrast, contains roughly 50 confirmed and possibly 30 unconfirmed galaxies, most of them unimpressive dwarfs. Many, perhaps most, galaxies exist in such small groups ...

In the local group of galaxies that also includes the Andromeda Nebula and our Milky Way, there are about 100 billion stars. According to astronomers' calculations, there should be many more.

The Local Group is a collection ofabout 40 galaxies, of which the MilkyWay and Andromeda are the dominant members. The rest of the galaxies are mostly small satellitesknown as "dwarfgalaxies" that ...

Galaxies, including the Milky Way, grow from thick, turbulent disks into layered structures. JWST’s images show this process ...

This portrait from the NASA/ESA Hubble Space Telescope puts the nearby galaxy NGC 4449 in the spotlight. The galaxy is ...

Thirty-two galaxies call the Ursa Major North Group home, including the bright spirals NGC 3631, NGC 4088, NGC 3953, and M109. The last of these looks most similar to the Milky Way.

Pericentric passage-driven star formation in satellite galaxies and their hosts: CLUES from Local Group simulations. Monthly Notices of the Royal Astronomical Society, 2021; DOI: 10.1093/mnras ...

Another of the local group galaxies in the collection is NGC 3109, seen below, which is also 4 million light-years away — but, this time, in the Hydra constellation.

Astronomers know that the Milky Way is parked within the Local Group of galaxies, an interstellar expanse extending 3 million light years across. But we know very little about the area just ...

Researchers discovered the first ultra-faint dwarf galaxies to be found around a spiral galaxy with the mass of the Milky Way that’s outside of the Local Group, the clustering of galaxies that ...
