M 110

About image 

The dwarf elliptical galaxy M110 (NGC 205) is one of the larger satellite galaxies of the Andromeda Galaxy M31.
The angular size of 21.9’x11’ corresponds to physical dimension of 16500x8300 light years, at a distance of 2.59 million light years from Earth.
Near the centre of the galaxy it is possible to see dust structures.
Inside M100 astronomers have discovered young stellar population, so this is the proof that also in a dwarf galaxy processes of stellar formations can take place.

In this image it is quite visible a kind of bright strip starting from M110 till the upper left side of the image: it is indeed the the stellar bridge that connects M110 to main galaxy M31.
