M104

This Messier object is an edge-on spiral galaxy located 30 million light years away in the constellation of Virgo at a declination of -12 degrees. It is a magnitude 8 galaxy which spans 7 arc-minutes in our apparent view. This corresponds to a diameter of 60,000 light years. The galaxy disk is tipped about 6 degrees to our line of sight.

Nicknamed the Sombrero Galaxy, this galaxy is the 16th brightest galaxy in the sky. It is visually striking because of the contrast between the thick dark dust ring and the bright central bulge.

Compared to most edge-on spirals, the galaxy disk here is surprisingly symmetric. It does not appear very warped and the core is well centered.

The Hubble image of the mouseover is an unusually large mosaic of 6 Hubble images stitched together to span the wide (for Hubble) view.

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.
