PASADENA, Calif., May 29 (UPI) -- NASA says data from its Wide-field Infrared Survey Explorer has yielded a new, improved family tree for asteroids in the main belt between Mars and Jupiter.
Millions of infrared snapshots from the asteroid-hunting portion of the WISE all-sky survey, called NEOWISE, have helped identify 28 new asteroid "families," NASA's Jet Propulsion Laboratory in Pasadena, Calif., reported Wednesday.
