A massive cosmic cataloguing effort released a new crop of star and galaxy data last week, noting the locations and brightnesses of hundreds of thousands of objects. Now you can fly through some of them in this new video -- click past the jump for a "flight through the universe."
Invisible, cold dark matter plays a major role in the evolution of galaxies, according to modern cosmological theory. The most advanced simulations of cosmic evolution show stringy tendrils of mass — dark matter — connecting giant clusters of galaxies via a vast cosmic web. Now for the first time, astronomers have been able to detect one of these filaments, sussing out its location by watching it warp light.
