This artist's conception shows green crystals of olivine raining down on a developing star like cosmic glitter. The crystals were spotted by NASA's Spitzer Space Telescope in a collapsing cloud of gas surrounding an embryonic star called HOPS-68. Stars form out of collapsing clouds. The growing stars feed off the clouds, accumulating more and more mass.
