Comet 41P (Artist’s Concept)
This artist’s concept depicts comet 41P, a tiny Jupiter-family comet, as it approached the Sun and frozen gases began to sublimate and shoot material off into space. Scientists analyzing observations from NASA’s Hubble Space Telescope found that these jets slowed the comet’s spin and then started it rotating in the opposite direction.
