Alderbaran

Sometimes the simplest composition of a single star is appealing.
This time it’s Aldebaran - the 14th brightest star in our night sky. Aldebaran "the follower" in Arabic, also known as Alpha Tauri, is the also the brightest star in the constellation Taurus where it defines the bulls eye. Aldebaran "follows" the Pleiades (the 7 sisters, or the 7 daughters of the Titan god Atlas and the ocean nymph Pleione).

At a distance of just 65 light years, it has a luminosity 518 times that of our sun, but is significantly cooler with a surface temperature of around 3700 C compared to the sun at 5800 C.

Taurus is a very old constellation with bovine associations reaching back to Gilgamesh-era Mesopotamia about 4000 years ago. The ancient Greeks, Egyptians, Babylonians, and Romans, all shared the concept of Taurus the Bull, though in some Native American cultures, Taurus was the head of a bison rather than a bull. The Inuit of the Arctic saw Aldebaran as a polar bear. Taurus seems to be charging eastward toward Orion, poised to defend himself.

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.
