This composite photograph is of NGC 2238, the Rosette Nebula, captured on January 10th and 14th, 2022. The Rosette is in our Galaxy and located in the Monoceros Constellation. It is about 5,500 light years away from Reno. This is an emission nebula, a large gas cloud emitting light in red Hydrogen wavelengths visible in this image. There is an open star cluster in the center of this gas cloud also visible in this image. Black cosmic dust lanes are visible in the arch over the center hole in the cloud. The Rosette is not visible to the naked eye.
