This image of NGC 2014, a violent star-forming area in the Large Magellanic Cloud, started from a true-color mapping of the narrowband filters. The blue cloud to the lower left is NGC 2020.

The blue parts of NGC 2014 and NGC 2020 are not, as one might expect, a reflection nebula, but ionized oxygen. (The OIII narrowband filters would not pick up much of a blue reflection nebula, except in the spectral continuum contribution to the image.) The loops and streamers in NGC 2014 arise from the violent star births and deaths it hosts and facilitates. Many of those young blue stars can be seen near the center of the image.

Most interestingly, perhaps, is that NGC 2020, the blue ring, was created by a single massive Wolf-Rayet star (about 200 thousand times brighter than our sun, throwing off a succession of outer envelopes of material. That WR star can be seen inside the ring of blue gas.

The image posted here is downsample almost 2::1. Image B is a patch at full resolution.

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.
