This Hubble Space Telescope image shows the sharpest view captured of the breakup of comet C/2019 Y4 (ATLAS).


The comet was set to be a bright object in the night sky during May 2020, but unfortunately for comet chasers it began to disintegrate in April.

The Earth-orbiting telescope was able to capture about 30 fragments of the comet - each roughly the size of a house - on 20 April 2020.

C/2019 Y4 (ATLAS) was discovered in December 2019 by the ATLAS (Asteroid Terrestrial-impact Last Alert System) and its break-up was confirmed in April 2020.

Two other comets will be visible in the night sky this month. Click on these links for guides to spotting Comet C/2020 F8 Swan and C/2017 T2 PanSTARRS.
