INFRARED EYE by Amy Mainzer ASTEROID TRACKS NASA's WISE space telescope captured dozens of asteroids in this infrared view from March 2010. Some stand out as a series of dots, where each dot in a track shows the asteroid captured at different times as it marched across the sky. The asteroid at center left is called 2415 Ganesa. The open cluster NGC 2158 glitters at center right. The green clouds are gas and dust. 12 APRIL 2025 * SKY & TELESCOPE
