Edits:
(1) We've added the fractional red shifts (z) from NASA's Million Quasar Catalogue. Closer inspection of the image and the catalogue show that two or three of the objects are near enough to be resolvable as galaxies. Most of the objects are billions of light years away. The furthest, with a fractional red shift of 3.5, is so far away that its light was emitted about 12 billion years ago.
(2) Gaffe: Although there were 35 objects found in our search of the catalogue, only 22 are on the map. I am the Count. I love to count. However, since the top half of the image is not covered by the catalogue, perhaps another 15 or 20 tiny little blue dots in the image are quasars too!
Andy, Jason, Steve, thanks for your kind comments.
Best,
Mike n Trish
