Messier 104 also known as the Sombrero Galaxy, is a majestic unbarred spiral galaxy located in the constellation Virgo.

The Sombrero Galaxy has an apparent magnitude of 8.98 and lies at a distance of 29.3 million light years from Earth.The galaxy has a diameter of approximately 50,000 light-years 30% the size of of our own galaxy.

Messier 104 has an incredibly bright nucleus, an unusually large central bulge, and a conspicuous dark dust lane in its disk. The appearance of the galactic bulge and the dust lane that crosses in front of it have earned M 104 the name Sombrero. The dust lane has the shape of a symmetrical ring around the bulge.

The Sombrero Galaxy’s large bulge and supermassive black hole at its core make the galaxy a popular target for study.

Messier 104 has a large population of globular clusters. Observations have yielded estimates in the range from 1,200 to 2,000 globulars.

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.
