M31

A first capture of M31. 1.7 hours over two evenings.

M31 (or Messier 31) or the Andromeda Galaxy is a magnitude 3.28 spiral galaxy in the constellation of Andromeda. Approximately 2.5 million light years distant. It is the nearest spiral galaxy to our own galaxy - the Milky Way. It is visible as a very faint smudge on moonless nights. But alas - my eyes are getting too old to see it naked eye anymore! It is one of the most distant objects visible to the naked eye. Some of the kids I do programs for can see it. Easy with binoculars. As somewhat of a mirror image of our own Milky Way, this monstrous aggregation of stars, dust and gas allows us to see the features of our galaxy that we cannot observe because we are inside it!

The two large glowing objects outside the main galaxy are companion galaxies of Andromeda - M32 and M110.

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.
