NGC 3077

This object is an irregular galaxy located only 12 million light years away in the constellation of Ursa Major at a declination of +69 degrees. This magnitude 10 galaxy, with a surface brightness of 13, spans 6 arc-minutes in our apparent view, which corresponds to a small diameter of 20,000 light years. This galaxy lies close to M81 and M82, making it a nice triplet for a wider field of view. Although a fairly obscure object, it the same size and brightness as M89.

Despite the dust that shrouds this area of the sky, many interesting details can be seen. The highlight of this object for me is the interplay of Ha regions, irregular dust lanes, and faint bright star clusters in and around the core. The Ha appears in to be strongest in a looping band around the edge of the core. This is likely indicative of a strong star forming region.

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.
