The Rosette Nebula (Caldwell 49) is a large spherical H-II region, near the huge molecular cloud in the constellation Unicorn (Monoceros). The cluster and nebula are about 5,000 light years away from Earth and have a diameter of about 130 light years. The mass of the nebula is estimated at about 10,000 solar masses.

In the centre of the Rosette Nebula lies the open cluster NGC 2244 (Caldwell 50), which is formed by the matter of the nebula. Gases are stimulated to glow by the surrounding hot O and B type stars. In the centre of the nebula, NGC 2244 has already cleared a bubble about 12 light years in size due to strong solar winds. Gas clouds still expand by some 20 km/s, so some spectacular star clusters will remain in a few million years.

The Rosette Nebula contains hydrogen and dust, which reflects the light of the very hot stars in NGC 2244, especially in the blue. The pronounced OIII line in the spectrum of the Rosette Nebula is also interesting, which indicates the presence of abundant oxygen.

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.
Dismissals 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.
