This is a fragment of a wall relief which shows Assyrian slingers in action. The four men appear to launch small round stones into the air, aiming at the enemy troops who stand at the top of the city walls to defend their besieged city. Some of the slinger stones were excavated at the main gate of Lachish.

NGC 2174 lies about 6400 light-years away in the constellation of Orion (The Hunter). It is not part of the much more familiar Orion Nebula, which lies much closer to us. Despite its prime position in a very familiar constellation this nebula is faint and had to wait until 1877 for its discovery by the French astronomer Jean Marie Edouard Stephan using an 80 cm reflecting telescope at the Observatoire de Marseille.
