Oct 20, 2005 - NASA's Spitzer Space Telescope has spotted what could be the early stages of planets forming around a failed star. The infrared telescope detected clumps of microscopic dust grains and tiny crystals orbiting five brown dwarfs. Similar material has been seen around other newly forming stars and in our own Solar System.
