M78 in HaRGB

M78 is a near neighbor of the Great Orion Nebula (M42), and like M42 is a star-forming region of the galaxy, 1340 light-years give or take from planet Earth. A little less than half the size of M42 -- 10 light years across versus 24 or so -- M78 is also primarily a reflection nebula, whereas M42 has both reflection and emission components. In other words, M78 is primarily illuminated by starlight bouncing off the dust and gas that comprise the nebula (like sunlight illuminating the moon by reflection), whereas much of M42's light is generated by excited, glowing gasses stimulated by ultraviolet radiation from powerful nearby stars.

Within M78, infrared observations have revealed more than 190 newly formed stars, and a further 45 young stars that are slowly contracting: the stellar equivalent of growing up.

Composed of a little more than 6 hours of exposures taken in early January, plus 3 additional hours from mid-December.

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.
