WLM, lonely remote galaxy – lagranepoca

ESO

As a tribe without contact in the depths of a forest, the distant galaxy WLM provides a rare glimpse of the galactic nature little altered by their environment.

this scene, captured from Chile by the OmegaCAM camera, installed on the VLT telescope of the European Southern Observatory (ESO) shows the lonely WLM.

Although considered part of our local group of galaxies, formed by dozens of them, WLM remains isolated at the outer edges of the group, making it one of its earliest members. In fact, it is so small and so remote, that may have never interacted with any other galaxy in the history of the universe.

WLM was discovered in 1909 by German astronomer Max Wolf and identified as a galaxy about fifteen years later by astronomers also Knut Lundmark and Philibert Jacques Melotte, hence the unusual nickname. This dark galaxy lies in the constellation Cetus (the sea monster), about three million light years from our Milky Way.
