M104, The Sombrero Galaxy

* Image Acquisition by Jim Misti / Steven Mazlin.

* Processing: Ruben Barbosa.

* Distance: 28 Mly.

The Sombrero galaxy (Messier 104, NGC 4594) is a spiral with a bright nucleus surrounded by a flat disc of dark material, which is 28 million light years away, in the direction of the constellation Virgo and has a diameter of 50.000 light-years.

It is the dominant galaxy of its M104 group and its redshift reveals that it departs from us at more than 1,000 km / s.

Its name derives from its appearance of profile that resembles a Mexican hat and the main characteristics are:

• A supermassive black hole with 1,000 million solar masses, an estimate resulting from the high velocity of stars near the nucleus;

• A galactic nucleus of reasonable size exhibiting intense brightness;

• Well defined spiral arms;

• A remarkable dark range of interstellar dust and gas that houses bright young stars;

• A populous system of approximately 2,000 globular clusters (10x more than those in the Milky Way) and

• A halo that stretches for thousands of light years.

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.
