The Rosette Nebula, also known as Caldwell 49, is an H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy.

The open cluster NGC2244 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter.

The cluster and nebula lie at a distance of around 5,000 light-years from Earth and measure roughly 130 light-years in diameter.

The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see.

The mass of the nebula is estimated to be around 10,000 solar masses.

Captured on 24 December 2020 using the Telescope Live CHI-4 astrograph located at the El Sauce Observatory in the Rio Hurtado Valley, Chile, South America the final result comprises 1hr 20mins of total integration.

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.
