Galaxies runner-up: NGC 3628 with 300,000 Light Year Long Tail by Mark Hanson (US). NGC 3628 is a popular galaxy target for both astrophotographers and visual observers, with its distinctive dust lane. Studies by professional astronomers have shown that the evolution of some galaxies are the product of a series of minor merges with smaller dwarf galaxies. This image is an epic undertaking of five years of exposures taken with three telescopes, although the majority of the exposure was in 2019. The goal of this mosaic is to show the tidal tail, measuring 300,000 light years in length. (Photo by Mark Hanson/2020 Astronomy Photographer of the Year)
