Galaxy Dwingeloo 1 Emerges

Explanation: Sometimes you can't see the forest for the trees. But if you look closely at the center of the above photograph , you will see a whole spiral galaxy behind the field of stars. Named Dwingeloo 1 , this nearby galaxy was only discovered recently (1994) because much of its light was obscured by dust , gas and bright stars of our own Milky Way Galaxy . In fact, all the individually discernible stars in the above photograph are in our Galaxy . Dwingeloo 1 turned out to be a large galaxy located only five times as distant as the closest major galaxy - M31 .
