An American Werewolf in Scorpio?
No, this dark nebula near the Dark Tower is known as SL 17.
Not very often imaged, but sure looks like a wolf!

About this Nebula

SL- 17 Fenrir Nebula

This cleverly found section of sky, located in the constellation of Scorpius [coordinates at the head section: 16:53:02.49000 -43:35:01.6400], that looks like a very shadowy, monstrous wolf like creature, bounding through space! It has two nicknames, either simply as the Wolf Nebula or perhaps better described as the Fenrir Nebula. The Fenrir name comes from Norse mythology, with the Wiki describing the Fenrir as “the father of the wolves Sköll and Hati Hróðvitnisson, is a son of Loki, and is foretold to kill the god Odin during the events of Ragnarök, but will in turn be killed by Odin’s son Víðarr”. Nice story.

The main subject is mostly made of a massive, heavy dense dusty region in space, the shape of the Fenrir. The reddish sections are emission nebula, populated by many stars of differing types and ages. (Steven Mohr)

It’s officially known as SL 17 and lies very close to Gum55 and The Dark Tower in Scorpius, however very little information can be found about it. A dark nebula is a type of interstellar cloud that is so dense that it obscures the light from the background stars.
