Messier 99 M99 (NGC 4254) in the constellation Coma Berenices

M99 was discovered by Pierre Méchain on March 17, 1781 then was reported to Charles Messier. M 99 was one of the first galaxies in which a spiral pattern was seen. The spiral pattern was first identified by Lord Rosse in the spring of 1846.

The galaxy has a normal looking arm and an extended arm that is less tightly wound. A bridge of neutral hydrogen gas links NGC 4254 with Virgoh21 a hi region and a possible dark galaxy. The gravity from the latter may have distorted M99 and drawn out the gas bridge, as the two galaxy sized objects may have had a close encounter, before they went their separate ways ,however the existence of Virgoh21 is unclear and another candidate is the lenticular galaxy NGC 4262 with this event having taken place 280 million years ago. It is expected that the drawn out arm will relax to match the normal arm once the encounter is over. Four supernovae have been observed in this galaxy. Info From Wikipedia

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.
