A Son of the Rock

While we’re on Astronomy.

Comet Iwamoto (its coma green in colour) moving in front of spiral galaxy NGC 2903. Featured on Astrionomy Picture of the Day for 19/2/2019. A time-lapse video compressing three hours into ten seconds. Two satellites zoom through the scene at about three seconds into the clip.

Comet Iwamoto last passed close enough to Earth to be seen about 1370 years ago.
