What is the formal designation for the Rotten Egg Nebula?
The formal astronomical designation for this nebula is OH 231.8+4.2. It is also sometimes referred to as the Calabash Nebula due to its gourd-like shape. It is classified as a bipolar protoplanetary nebula.
Where is the Rotten Egg Nebula located?
This nebula is located within the Puppis constellation, which is visible in the southern celestial hemisphere. It lies at a distance of roughly 5,000 light-years away from Earth. It is a relatively close object in astronomical terms, making it a good subject for study.
What is happening at the center of the Rotten Egg Nebula?
At the center of the nebula is a dying star system, featuring a young proto-planetary object named QX Puppis. Powerful jets of gas are emanating from this central object at incredibly high speeds. These outbursts of gas are what created the surrounding, colorful cloud we see today.
