NEOWISE

NEOWISE is a NASA space telescope originally launched in 2009 to study the universe in infrared light. After its primary mission, it was repurposed in 2013 to focus on identifying and tracking near-Earth objects—asteroids and comets that come close to our planet. By detecting their heat emissions, NEOWISE helps scientists determine their size, composition, and trajectories, crucial for assessing potential impact risks. Its infrared observations allow it to see objects that are dark or hidden in visible light, making it a vital tool for planetary defense and understanding our solar system.
