Earthquake sensors can hear space junk falling to Earth

Thousands of discarded human-made objects are circling Earth, and when pieces of that space debris fall back to the surface, they can pose risks to people on the ground. To help identify where debris may come down, a scientist at Johns Hopkins University has contributed to a new approach that uses existing earthquake monitoring systems to track objects as they reenter the atmosphere.
