IC 2631 in Chamaeleon

This is a view of the Chamaeleon I portion of the Chamaeleon molecular cloud complex, a star forming region close to our solar system, containing proto stars, reflection nebulae and Herbig-Haro objects. This lies close to the south celestial pole and is in fact circumpolar for most southern hemisphere observers. It's a remarkable part of the sky containing many objects of interest. The most prominent reflection nebula is IC 2631 (right mid), caused by a young star formed from the surrounding molecular cloud. Further to the right in this image is NGC 3620, a distant barred spiral galaxy.

The cone-shaped orange reflection nebula (the Chamaeleon Infrared Nebula or GN 11.07.3) is lit by intense infrared emissions from a low mass star at the apex of the cone. The star is eclipsed by a band of dust thought to be a protoplanetary accretion disc which is just visible in this image.

The other two reflection nebulae are Ced 110 and Ced 111, catalogued by Swedish astronomer Sven Cederblad in the 1930s. Lying between them is a pair of Herbig-Haro objects associated with newly formed stars.

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.
