UGC 10822 (Draco Dwarf)

Another dwarf galaxy in our local group about 280000 light years away in constellation Draco.
Measurements of the velocities of stars in the outer region of the galaxy suggest a halo of dark matter holding significantly more mass than represented by the visible objects in that galaxy. The ratio of dark matter to visible matter is one of the highest observed in a galaxy so far. It has therefore drawn much attention in dark matter research in general. The assumed distribution of dark matter seems to be very consistent with the current LCDM (Lambda Cold Dark Matter) cosmological model.
Its stars are mostly more than 10 billion years old and star formation rate is currently pretty low due to lack of dust and gas. There might have been a small star burst about 2-3 billion years ago.
Note also the faint clouds on the bottom left of the image, probably belonging to the IFN within our own galaxy.
