Are you reading this correctly?  Other galaxies that have been hidden from us?  Wow:

As far as we know, the Milky Way is orbited by 49 other galaxies, but this research suggests that perhaps there are other dark galaxies, inside our own cosmic neighbourhood, that have remained hidden because of their diffuse, ghostly appearance.

Crater 2 was first detected in January, when astronomers used a computer algorithm to study images taken by the Very Large Telescope in Chile, and then pinpoint regions where there might be unusual clustering of stars

Also a note more and more discoveries have been coming out of the large telescope in Chile lately.  It is not just the hubble producing the incredible pics!  That region of Chile has some of the best conditions.

Stay tuned for more updates on this find.
