Within this image lie multiple HII clouds, all of which reside within the Large Magellanic Cloud. Among the various HII clouds is NGC 2014 (see image B), a ‘supershell’ or ‘superbubble’, which is a cavity within a bubble carved out by supernovae and stellar winds. Some bluish areas in the clouds (e.g., NGC 2020, and the area around NGC 2040) are reflection nebulae from embedded clusters young, hot stars. Stars are so abundant in this image, the entire image has a sandy, grainy appearance. The image includes stars below magnitude 21.54, according to in the catalogs I can access.

Speaking of ‘Superbubbles,’ our solar system lies near the center of an old superbubble, the “Local Bubble”, which is roughly 300 light-years across and contains an average of 1/10 as many atoms/cm3 as the surrounding areas of the Milky Way.

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.
