Rosette Nebula

This nebula is such a cool object with so much going on inside it. Rosette (NCG 2237) is an emission nebula and an active star forming region of the Milky Way roughly 5000 light years from Earth. At the center of the nebula is the star cluster NGC 2244 which astronomers believe formed roughly 5 million years ago, a blink of the eye in galactic time scales. This open star cluster contains a number of very large O-type stars which were originally formed out of the nebula's gas and whose stellar winds have since cleared out the central part of the nebula. When I say these stars are very large I mean like 50-60 times the mass of the sun and 400,000-450,000 times more luminous! Rosette is still forming new stars in the denser parts of the nebula including the distinctive dark clouds in the bottom right portion of my image.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
