Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.
Explanation: Sometimes you can't see the forest for the
trees. But if you look closely at the centre 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.
