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]
