SUMMARY: Astronomers have discovered a dusty disk around a young star that could be in the process of forming new planets. The star, which is approximately the size of our own Sun, was observed using NASA's Spitzer Space Telescope. The star, known as HD 12039, is about 30 million years old; the age at which astronomers believe the terrestrial planets in our Solar System had nearly formed. Based on Spitzer's analysis to date, it looks like only 1-3% of young Suns have a disk like this surrounding them.
