IC 405 (Sh2-229, Caldwell 31), the Flaming Star Nebula in Auriga

Casitas de Gila, Gila, NM, October 16 - 17, 2023IC 405, the Flaming Star Nebula (SH 2-229, Caldwell 31) is an emission and reflection nebula in the constellation Auriga. The “smoke” from the flaming star is the bluish structure that appears to emanate from the bright star AE Aurigae. This is a cloud of dust reflecting the light of the star whose strong stellar wind has shaped the gas and dust into this fascinating structure. The surrounding red area is the hydrogen-alpha emission in a large gas cloud that is irradiated by the star. IC 405 is about 1,500 light-years away from Earth.

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.
