100 plus hours on IC 405 and 410 (Collaboration by Fort Worth Astronomical Society)

On behalf of the Fort Worth Astronomical Society, an astronomy club founded in 1949, we respectfully present the attached image of the Flaming Star and Tadpoles Nebulae, known to astronomers as IC 405 and IC 410. The image is the result of a collaboration of five club members who collected more than 100 hours of data using different telescopes and cameras as indicated in the equipment description.

The Flaming Star Nebula is illuminated by AE Aurigae, a blue O-type main sequence variable star. AE Aurigae is a "runaway star" that originates from the Trapezium cluster in the Orion Nebula. The collision that ejected AE Aurigae occurred about two million years ago. Although it illuminates the Flaming Star Nebula, AE Aurigae was not formed from it. It is merely "passing through" the nebula at high speed but, in the process, it produces a ferocious bow shock.

In contrast, the Tadpoles Nebula, IC 410, spans about 100 light-years across. An open star cluster inside the nebula (NGC 1893) lights up the nebula's gases. There is significantly more signal from ionized oxygen in this nebula, and the blue color inside comes mostly from that element, rather than reflected light. The intense radiation and stellar winds from the cluster have sculpted the two tadpole-shaped structures located in the nebula. Composed of denser, cooler gas and dust, the tadpoles are about 10 light-years long and are likely sites of ongoing star formation.

Attribution goes to the Fort Worth Astronomical Society and the following individuals listed in alphabetical order: Christopher Ashford, Stephen Kennedy, Jim Potts, Bob Sirkis, and Peter Tijerina. The data was collected and integrated by Stephen Kennedy and processed by Christopher Ashford. No AI was used in the data collection or processing of this image.

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.
