NGC 206 - Open Star Cluster in the Andromeda Galaxy (M31)

NGC 206 is one of the largest star forming regions known in our local group of galaxies, much larger than the clusters of stars of M24 in the Sagittarius Star Cloud of our own Milky Way Galaxy. It was originally identified by William Hershel as a star cluster back in 1786. NGC 206 contains more than 300 very bright stars, but only relatively few are fully resolved in this image cropped from a much larger view of the entire galaxy.

NGC 206 is located in the southern region of the Andromeda Galaxy (M31) at the intersection between two spiral arms and is responsible for enhanced levels of star formation. The bright, blue stars of NGC 206 indicate its relative youth in cosmic terms. Its youngest massive stars are less than 10 million years old. Much larger than the clusters of young stars in the disk of our Milky Way galaxy known as open or galactic clusters, NGC 206 spans about 4,000 light-years across. That's comparable in size to the giant stellar nurseries of NGC 604 in the nearby spiral Triangulum Galaxy (M33) and those in the Tarantula Nebula, in the Large Magellanic Cloud visible only in the southern hemisphere. Among those stars are several Cepheid variable stars, which are very luminous variable stars with a strong direct relationship between their variable’s luminosity and pulsation period. That secures their status with astronomers as important standard "candles" for establishing the galactic distance scales.

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.
