This animation illustrates new results from NASA's Wide-field Infrared Survey Explorer, or WISE, taken during its one-year survey of the sky in infrared light. The asteroid-hunting portion of the mission, called NEOWISE, scanned for asteroids both in the main belt between Mars and Jupiter, and those near Earth. The observations led to a reduced estimate of the total population of medium to large-sized near-Earth asteroids (objects larger than 330 feet or 100 meters).
