NGC 6621 expand

This object is an tiny pair of merging spiral galaxies in the constellation Draco. It lies at a distance of circa 260 million light-years. NGC 6621 interacts with NGC 6622, with their closest approach having taken place about 100 million years before the moment seen now. NGC 6621 is the larger of the two, and is a very disturbed spiral galaxy. The encounter has pulled a long tail out of NGC 6621 that has now wrapped at the north behind its body. The collision has also triggered extensive star formation between the two galaxies. It has an apparent size of 1'.9 x 0'.7 and an apparent magnitude of 13.6 (B). Below you can find a cropped and zoomed version.
