The Small Magellanic Cloud & 47 Tucanae (NGC 292 & NGC 104)

47 Tuc (NGC 104) is the 2nd brightest globular cluster in the night sky. It lies approx. 15,000 ly away and
has in excess of 10,000 very old stars (est. 13 billion years). It was formally described and catalogued by
de Lacaille in the 1750s.

The Small Magellanic Cloud (SMC) is a satellite dwarf galaxy of our Milky Way Galaxy. It lies approx.
200,000 ly away and thus is one of the most distant objects visible to the naked eye. It is 18,900 ly
across, and contains several hundred million stars. It is speculated that the SMC was once a small
barred-spiral galaxy in its own right. It has a long history of being observed and described by early
mariners and astronomers, being visible from northern latitudes well south of Europe.

As a bonus, the globular cluster, NGC 362 (Caldwell 104) can be seen to the north of the SMC. It lies
some 29 ly away, making it extremely small in comparison to 47 Tuc. Astronomers have determined
from measurements of its stars' "metallicity" that this globular is likely to be younger than most at
just 11 Gyo (11 billion years old). Its orbit around our galaxy's core is highly eccentric, approaching it
to within 3,200 ly. It was first recorded by James Dunlop from Paramatta in 1826.

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.
