One-armed galaxy Arp 291 captured in new survey image

A Sloan Digital Sky Survey image of Arp 291, also known as UGC 5832, is drawing attention. The barred spiral galaxy has only a single prominent arm, and astronomers suspect it may be interacting gravitationally with a smaller galaxy located nearby, which could explain its unusual shape. The image, released via Wikimedia Commons, is being shared among space enthusiasts who follow the Arp catalog of peculiar galaxies.

Why now: The striking one-armed structure and possible galaxy interaction make the image a curiosity for space audiences.
