NGC 891

NGC 891 and a bunch of smaller galaxies from Bortle 1 skies at Kodachrome State Park in south-central Utah. This is in the constellation Andromeda. Here is some information about NGC 891:

Classified as an edge-on unbarred spiral galaxy. Its edge-on orientation gives astronomers a unique perspective to study its structure and properties.
Estimated diameter of about 100,000 light-years. It is located at a distance of approximately 30 million light-years from Earth.
The dark lane is made up of dense interstellar dust, which blocks and scatters the light from stars behind it. The dust lane is a defining feature of this galaxy's appearance.
Active Galactic Nucleus: NGC 891 has an active galactic nucleus (AGN) at its core. The AGN is fueled by a supermassive black hole, which accretes matter from its surroundings, emitting significant amounts of energy across the electromagnetic spectrum.
Spiral Arms: Despite its edge-on orientation, NGC 891 displays faint, intricate spiral arms that extend from its central region. These arms consist of young, hot stars and regions of active star formation.
NGC 891 is often compared to the Milky Way galaxy due to their similar size, structure, and characteristics.

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.
