Yet another nebula located in the constellation of Orion, this HII region contains both emission nebulae (red) and reflection nebulae (blue). The star 42 Orionis probably illuminates the entire reflection nebula. (42 Orionis is the bright star just about in the center of this picture.)

Have you ever used the word “proplyd” in a conversation, say with a Handy Hardware Man? Well, as I just learned, it’s a quick way to say, “ionized protoplanetary disk.” Well, there are six of those hidden in this picture. I would love to point them out, but the CDK17 just doesn’t have the resolving power that the HST has, so let me tell you that they lie in a shock wave only 48x as far from the young, hot star 42 Orionis as the Earth is from the Sun.

Nonetheless, I hope you see details in this image that most powder-puff renditions miss.

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.
