Comet!? No- this object was put into the correct category as a diffuse nebula. The bright star at the tip of the cloud of gas is called R Monocerotis. It is a variable star that is actually in the background of the cloud of gas.
Summary

English: Comet!? No- this object was put into the correct category as a diffuse nebula. The bright star at the tip of the cloud of gas is called R Monocerotis. It is a variable star that is actually in the background of the cloud of gas. The gas cloud is around 1 light year in extent and due to the variability of R Mon, the entire nebula changes in its brightness. However, R Mon is mysterious because the mechanism of its variations is uncertain. The most accepted explanation is that there exist clouds of gas and dust very close to R Mon and these clouds eclipse R Mon (as they orbit about it) casting shadows onto the foreground nebula.This image was taken as part of Advanced Observing Program (AOP) program at Kitt Peak Visitor Center during 2014. |
