Flying through the universe

In 1946 Sputnik escaped the Earth’s atmosphere, turned its camera back on “home” and took the first photo of our planet from space. It was a milestone in space technology.

Photos are great. Indeed a single photo is worth a thousand words. But what about video? This week the largest sky survey, SDSS, released the largest three-dimensional video of the universe, yet.

See how galaxies are stringed together in massive galaxy clusters as you fly through space. It’s a truly remarkable experience.
