Messier 101, also known as the Pinwheel Galaxy, is a large spiral galaxy in the constellation Ursa Major. It is around 21 million light years away from Earth and is one of the brightest and most massive spiral galaxies in the Local Galaxy Group.
The Fire Wheel Galaxy has a striking spiral structure characterized by extended spiral arms. They extend far around the bright central region and are filled with numerous young, massive stars, star-forming regions and luminous gas clouds. The galaxy also has a relatively large and bright core.
With a diameter of around 170,000 light years, Messier 101 is one of the largest spiral galaxies we know of. It belongs to the classification of grand design spiral galaxies, as its spiral structure is particularly clear and symmetrical.
The galaxy is also known for its high rate of star formation. There are numerous areas of intense star formation in the spiral arms, where young, massive stars are formed. These stars radiate large amounts of energy and influence the environment by heating and ionizing gas and dust.

SN 2023ixf is a type II supernova (core collapse) located in the Windmill Galaxy (M101). It was first observed on May 19, 2023 by Koichi Itagaki and immediately classified as a type II supernova. The supernova is about 21 million light years away from Earth and is expected to have left behind either a neutron star or a black hole, based on current models of stellar evolution.

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.
