NGC2237 Rosette Nebula

The Rosetta Nebula (NGC2237) is a giant molecular cloud visible in the constellation of the Unicorn and covers the sky roughly twice the size of the full moon. The open cluster in the center (NGC2244) is closely related to the nebula, its bluish stars formed from the material of the nebula made up of dust and gases. The nebula and open cluster are approx. It lies 5,000 light-years from Earth, and its diameter is roughly 130 light-years. Radiation from young stars excites atoms in the nebula, causing them to emit radiation themselves, creating the emission nebula we see. These stars are "very young" approx. They formed from the material of the nebula 4 million years ago, and star formation continues today. Massive and hot stars together produce a particularly intense stellar wind. This continuously blows the material of the fog outwards from the central part, and thus a shape similar to a giant bubble is created, which is also clearly visible in the picture.

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.
