The Whirlpool galaxy (M51) in HaLRGB

The Whirlpool Galaxy is a spiral galaxy that is located about 23 million light-years away from Earth in the constellation Canes Venatici. It is also known as Messier 51 or M51, and is one of the most famous and well-studied galaxies in the sky. The galaxy's distinct spiral shape and bright nucleus, which is visible even through small telescopes, make it a popular target for amateur and professional astronomers alike. The galaxy's spiral arms are dotted with star-forming regions and clouds of gas and dust, which give rise to new stars. These features, along with the galaxy's close proximity to Earth, make it an important object for studying the formation and evolution of galaxies. (OpenAI)

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.
