5,000 Robots Merge to Map the Universe in 3D

How do you create the largest 3D map of the universe? It’s as easy as teaching 5,000 robots how to “dance.” DESI, the Dark Energy Spectroscopic Instrument, is an experiment that will target millions of distant galaxies by automatically swiveling fiber-optic positioners (the robots) to point and gather their light. In creating this detailed map, scientists hope to learn more about dark energy, which is driving the accelerating expansion of the universe. More>
