RCW 135 is a planetary nebula in Scorpius. [1] It was discovered by Rudolph Minkowski in 1946. [2]

Structure

The nebula is a series of loops and arcs, surrounding a bright shell. Some outer loops point away from the center of the nebula. [3] The total size of the nebula is 10", however the central shell is only 2.5". [4] It has been proposed that the nebula contains a triple-star system at its core. [5]
