Animation of Hubble’s Observations of Comet C/2019 Y4 (ATLAS)

This animation dissolves between the Hubble Space Telescope’s observations of Comet C/2019 Y4 (ATLAS) on 20 and 23 April. The NASA/ESA Hubble Space Telescope has provided astronomers with the sharpest view yet of the breakup of Comet C/2019 Y4 (ATLAS). The telescope resolved roughly 30 fragments of the comet on 20 April and 25 pieces on 23 April.  The comet was first discovered in December 2019 by the ATLAS (Asteroid Terrestrial-impact Last Alert System) and its fragmentation was confirmed in April 2020.
