The ALFALFA Sky II : The Thrilling Sequel

Got my colour issues all sorted. For those who missed the earlier posts, this shows the visible light component of 22,935 galaxies from the ALFALFA hydrogen survey - using the actual image of each galaxy, from the Sloan Digital Sky Survey. Galaxy sizes have been exaggerated by a factor of forty (not five as I earlier reported). More detail in the link below... it's a post from 2013, but I've updated it to include the new data/techniques. The previous version had a poxy 11,710 galaxies, so this one is like, waaay better.

Go straight to the full HD video here, partly in 3D if you've got any red-blue glasses hanging about :

    Wow, great job!
    Made me wonder just how fast you would have to travel to actually get that perspective.

    Thanks Bryce Alexander !
    About 1.3 million light years per second... or about 40 trillion times the speed of light. :)
