December 3, 2007 Infrared imaging technology on NASA's Spitzer Space Telescope has been used to locate some of the youngest solar systems yet detected. Astronomers at the University of Michigan made the discovery when using the telescope to more closely observe gaps in protoplanetary disks of gas and dust surrounding the young stars UX Tau A and LkCa 15 in the Taurus star formation region.
