Researchers at MIT have developed a method to detect small asteroids in the main asteroid belt, significantly improving our ability to spot objects as little as 10 meters across.

This new technique, which identified 138 space rocks ranging from bus-to stadium-sized, allows for earlier detection and better tracking of potential near-Earth objects, enhancing planetary defense. The approach, using data from telescopes initially aimed at exoplanets, has uncovered over a hundred new asteroids, with implications for understanding asteroid origins and collision processes.
