NASA's New Horizons Detects Dusty Hints of Extended Kuiper Belt
Speeding through the outer edges of the Kuiper Belt, almost 60 times farther from the Sun than Earth, the New Horizons Venetia Burney Student Dust Counter (SDC) instrument is detecting higher than expected levels of dust - the tiny frozen remnants of collisions between larger Kuiper Belt objects (KBOs) and particles kicked up from KBOs being peppered by microscopic dust impactors from outside of
