I had to look up why the Carina Nebula was so named, because the word is used in a number of different settings. In this case it was because the Carina constellation is located in the keel part of the Argo Navis constellation.
Wikipedia mentioned that a part of the Carina Nebula is called the Keyhole Nebula, and the photo of THAT is so interesting that I've posted part of it separately below!
