SH2-278 / LDN1634 - A Cosmic Smoke Monster

Nestled between the Orion nebula and the Witch Head nebula, SH2-278 is an often overlooked dark nebula complex rimmed with abundant Ha emissions. This type of nebulosity is aptly called Bright Rimmed Clouds or BRCs.

Several Herbig Haro objects are revealed by multiple red knots of nebulosity visible near the center-left of image. These are narrow jets of partially ionized gas that are launched by young protostars that have formed in within the dense molecular cloud. The gas collides with adjacent matter which results in the bright emission.

The blue smudge on top right of the image is a bit of interstellar dust that is reflecting blue light from nearby bright star Rigel. Rigel is also responsible for illuminating the nearby Witch Head nebula.

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.
