M45 - The Pleiades in Taurus

One of the most recognized sights in the autumn/winter sky, M45 is an open star cluster in the constellation Taurus. The cluster had many names in antiquity, today we refer to the name of Greek origin the Pleiades (the Seven Sisters). The Seven Sisters is one of our closest star clusters, thought to be ~430 LY away. The blue nebulosity is caused by starlight reflections from dust; however this dust is not the medium from which the stars were formed. The Pleiades cluster just happens to be passing through an interstellar region that contains a great deal of dust. The Pleiades contains over 1000 stars, all which formed approximately 100 million years ago.

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.
