Sombrero Galaxy (M104)

The hallmark of this nearly edge-on galaxy is a brilliant, white, bulbous core encircled by thick dust lanes comprising the spiral structure of the galaxy. This dust lane is the site of star formation in the galaxy.

The center of M104 is thought to be home to a massive black hole.Embedded in the bright core of M104 is a smaller disk (not visible in this image), which is tilted relative to the large disk. X-ray emission suggests that there is material falling into the compact core, where a one-billion-solar-mass black hole resides.

M104 is located 28 million light-years away in the constellation Virgo, and with a mass equal to 800 billion suns, it is one of the most massive objects in the Virgo galaxy cluster. M104 was discovered in 1781 by the French astronomer and comet hunter Pierre Méchain, one of Charles Messier’s colleagues.

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.
