A new image from the Gran Telescopio Canarias shows Arp 288, also known as NGC 5221, a galaxy with a long tidal tail stretching roughly 260 thousand light years from its center. A supernova that appeared in that tail in 2016 acted as a backlight, revealing that the tail contains surprisingly little dust, a detail astronomers find notable.
