Messier 109 (M109) is a barred spiral galaxy located in the constellation Ursa Major. It's about 83.5 million light-years from Earth and is the furthest object in Messier's catalog. M109 is also known as NGC 3992.

Here are some other facts about M109:

M109 is the brightest member of a group of roughly 80 galaxies known as the Ursa Major Galaxy Cluster.

M109 is home to a trillion stars.

M109 is different from other S-shaped galaxies because its bar ends in short counterclockwise arms.

M109 can be seen southeast of the star Phecda (γ UMa, Gamma Ursa Majoris).

M109 is bright enough for its core to be seen through an 80mm instrument under good conditions.

Charles Messier observed M109 in 1781 and it was officially added to the Messier catalog in 1953.

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.
