HOTPE - thanks for the link regarding Laniakea. This is a really nice discovery. For decades astronomers have wondered about the "Great Attractor" and why our local group of galaxies is heading towards it, but now it seems it's the centre of a galaxy super-cluster with us in the suburb regions. Brent Tully (UH IfA) is a big player in the field of local galaxies and cosmology. There is a video about the discovery on Brent's homepage (http://www.ifa.hawaii.edu/~tully/) but it may be a little too technical for the layperson.
