Astronomers discover asteroid treasure trove in old Hubble Space Telescope data

Astronomers have revealed the trails of nearly 1,500 new asteroids hidden in data gathered by NASA's most venerable space telescope. In a new study, astronomers and a team of amateur scientists have worked together to comb through archival data from the Hubble Space Telescope. The project began on International Asteroid Day in 2019, when a team of astronomers launched the "Hubble Asteroid Hunter" project on Zooniverse, a popular platform for crowdsourcing science. The project's aim was to identify asteroids in old data from Hubble; signals that, in other studies, might have just been filtered out as noise.
