M33 Triangulum Galaxy

The Triangulum Galaxy is a close neighbor to our own Milky Way, only 3 million light-years away. It is the third largest galaxy in our local group, behind Andromeda and the Milky Way. It is a loosely defined spiral, noted for massive regions of ionized hydrogen gas clouds that drive star formation. Some of the largest stellar nurseries ever observed are in Triangulum. Those sites see the formation of massive, super hot, and short lived stars with many burning out in millions of years compared to billions of years for typical stars like our own. The red glow seen in these regions is emitted by ionized hydrogen energized by the intense ultraviolet radiation given off by the massive stars produced here.

Triangulum gets it's M33 designation from being the 33rd object cataloged by Charles Messier in 1764. He was looking for comets, and when he found fuzzy patches of light that didn't move, he noted their position and description so as not to waste time on them in future surveys of the sky. The irony being that Charles Messier built a list of things to ignore but his list is now known for the best things backyard astronomers can look at.

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.
