Description

The Rosette Nebula, despite being 5000 light years from Oklahoma City, was named the official state astronomical object in 2019 of Oklahoma.....snatching up and monopolizing for Oklahoma one of the prettier nebulas in my mind.....the winter rose!

The center star cluster (NGC 2244) was discovered by William Herschel in 1784 (123 years before Oklahoma statehood so we all had our chance) and is made up of massive new born stars which are blowing out the nebula with their stellar wind while compression of these gases leads to further star formation. These massive O-type stars can have a mass between 10,000 to 1,000,000 times that of our sun. They live fast and burn hot typically ending in violent supernova explosions. They are very rare, accounting for about 1 out of three million stars....but they are so bright that actually 4 of the 90 brightest stars visible from Earth are type O (S Monocerotis from the "trunk" of the Christmas Tree nebula is a typical example). Many smaller new born stars are visible throughout this nebula and primarily what you are seeing. All of this ionizes the surrounding hydrogen giving off the reddish glow as well as bathing the whole region in X-ray radiation which can be detected with different telescopes than my little Redcat.

So....good for you Oklahoma.....kind of a jerk move to claim something that can be seen by 49 other states, 194 other countries (at least remotely if they are in the incorrect hemisphere), and countless other citizens of other planets.....cannot say that I blame you though!
