Mosaic out of 5 images - Molecular Clouds in Constellation Chameleon

The southern constellation of Chamaeleon (at a distance of ∼160 - 180 pc) contains one of the nearest groups of dark clouds.

There are 3 main complexes. Cha I, Cha II and Cha III.

This mosaic shows in the upper right corner the dark cloud complex

Chameleon I, which extends down to the lower left where it reaches the

border of dark cloud complex Chameleon III which i show in another picture

in my gallery of astrobin.

The "Chamaeleon I" complex is a place of young low mass stars, resulting in various reflection nebulae - IC 2631, and the blue nebula Ced 111 and the white reflection nebula Ced 110.

The obscuring mass of thick brown dust in the upper right region absorbs the blue light of distant stars making them appear much redder than they actually are. This process of interstellar reddening also changes the light of galaxies behind, reducing the blue light of these distant galaxies.

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.
