M33 - Triangulum Galaxy (Ha+LRGB)

M33 is a Spiral galaxy about half the size of the Milky Way and 2.73 million light-years from Earth and located in the triangle-shaped constellation Triangulum with a size of 25 million individual stars in a 14,000-light-year-wide span and with a mass of approximately 5×10^10 Solar.

Red-colored (H II) regions scattered throughout this image reveal numerous sites of rapid star birth in M33. A bright red patch in the near upper-right of the center of this image, called NGC 604, is the largest star-forming region in M33 and one of the largest stellar nurseries in the entire Local Group - the Andromeda Galaxy, the Milky Way, and Triangulum Galaxy.

M33, with an apparent magnitude of 5.7, is one of the easiest objects that keen-eyed observers can view with the unaided eye in the clear and dark sky. It is best observed in October.

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.
