Sh 2-294, also known as the Octopus Nebula, [2] is a nebula in Monoceros. It was discovered by Wolfgang Strohmeier in 1950, during a photographic survey. [3]

Structure

It is ionized by a single B0 star, MFJ Sh 2-294 4. It has an unusual amount of dust, and is uncommonly red. A star cluster has begun to form in the nebula, with star formation caused by the expansion of the nebula. [4] The nebula contains 38 known young stellar objects, as observed by the Spitzer space telescope. [5]
