First they gave us a high-res tour of Mars -- now Microsoft has made the largest and clearest night-sky map ever. It's a terapixel image: 1,000 000,000,000 pixels.
The software giant’s Terapixel project stitched together 1,791 pairs of red-light and blue-light plates from telescopes in California and Australia. The result is the map above, which covers the night sky of the northern and southern hemispheres.
Using Microsoft's WorldWide Telescope program, you can now take an interactive tour of Mars with the highest-resolution images available of the Red Planet -- something even scientists have never been able to see before.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
