The Milky Way’s (almost) identical twin

The Milky Way’s (almost) identical twin

Wonderful article about this almost twin of the Milky Way, but is really 140,000 light years across or 40% times bigger than the Milky Way. Head over and take a look at the comparison of potw1035 and the Milky Way.

In the image above image you can see a wonderful bar from all the stars near the central region and the reason the image was taken, a supernova, SN2004ef, just below and to the left of the core, the bright blue star there. That is one incredible sized galaxy and very, very beautiful. Ever wonder if some other civilization has imaged the Milky Way and what they have had to say about it?
