Astronomers have used 19 years' worth of Hubble data to detect over 1,000 previously unknown asteroids in our solar system.

Like boulders, rocks, and pebbles scattered across a landscape, asteroids come in a wide range of sizes. Cataloging asteroids in space is tricky because they are faint and they don't stop to be photographed as they zip along their orbits around the sun.

Astronomers have employed a novel approach with the Hubble Space Telescope to uncover a largely unseen population of smaller asteroids in our solar system.
