Southern Cross aka the Crux constellation is a Southern Hemisphere target par excellence located 25 degrees away from the SCP (south celestial pole). It is the smallest constellation in the night sky as a whole, and also referred as an asterism.

Many counties have depicted it on their flags symbolizing their southern locations, but Brazil had a different take (flag in the 1st comment), they implemented it with a twist (literally):

All the stars depicted on the Brazilian flag are actually flipped, it represents stars observed from the outer space far-far away from Earth, as 'observed' on 15 November 1889 at 08:30 towards Rio de Janeiro. I am not sure whether a flat earther or an avantgardiste was behind this idea, but that outer-space observer, if ever existed, would have definitely had a different view.

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.
