Messier 100 (also known as NGC 4321) is located within the southern part of constellation Coma Berenices at approximately 55 million light-years distant from Earth.

It is one of the brightest and largest galaxies in the Virgo Cluster, with a diameter of 110.000 light years, being an example of a grand design spiral galaxy.

This galaxy seems to be almost a perfect symmetric (with one arm’s exception), similar to our own Milky Way, has a brilliant core (caused by an active supermassive black hole), two prominent arms of bright blue stars well defined, several fainter arms and some dust lanes.

The blue stars in the arms means intense star formation activity that were formed recently from density perturbations caused by interactions with neighboring galaxies, NGC 4323 (on the right) and NGC 4328 (below the M100, not visible in this image). NGC 4323 is connected with M100 by a bridge of luminous matter.

Studies of variable stars in M100 have played an important role in determining the age of the Universe.

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.
