Ninety seconds is all it takes to traverse almost half a million galaxies in this visualisation of our near universe.
Building on the results of the Sloan Digital Sky Survey, perhaps the most comprehensive, dedicated astronomical map in history, a team at John Hopkins University have created a rapid-fire tour of our galactic neighbourhood. How rapid? One YouTube commenter estimates it at 1,262,304,000,000,000 times the speed of light. At this pace, entire galaxies drift by like dandelions on the breeze. If this seems expansive, consider it only covers 1.3 billion light-years of space. The next data set they're looking at contains seven billion. And on and on it goes.
