| Object type: | Dwarf galaxy (dwarf Irr) | |
| Size: | 12' x 4' | |
| Magnitude: | 11.0mag | |
| Constellation: | Cet | |
| Distance: | 3.0 Mio Ly | |
| Notes: |
The irregular dwarf galaxy WLM was discovered in 1909 by Max Wolf and it was
identified as a galaxy about 15 years later by Knut Lundmark and Philibert
Jacques Melotte. The WLM galaxy is a member of the Local Group of
Galaxies. It can be found inside the constellation Cetus in a distance of 3.0
million light-years. Being at the edge of the Local Group has protected WLM
from interactions and mergers with other galaxies. Therefore this galaxy
could be described as an astronomical “living fossil” as it seems to have
developed without ever interacting with any other galaxy since it formed
billions of years ago. It's "pristine" stellar population and state make it
particularly useful for comparative studies. Three distant galaxy clusters are also visible in the above image:
