The idea that the earth goes around the sun has an ancient precedent: the heliocentric theory of Aristarchus of Samos.
A look at what he thought, why he thought it, and what other people thought of it.

The #Aristarchus region is interesting for a number of features, but the Crater itself is in fact very bright.
Here's a view of the region taken with an #ETX90 telescope.
ShadowCam maakt spectaculaire beelden van de zuidpool van de Maan
NASA’s ShadowCam vliegt met vijf andere instrumenten aan boord van KARI’s Korea Pathfinder Lunar Orbiter (KPLO), ook bekend als Danuri, die op 4 augustus 2022 werd gelanceerd.

Here you can see #Aristarchus and the #Schrötertal al little bit closer
At the right there is #Kepler and big #Copernicus. On the left side, near the terminator, lays bright, shiny #Aristarchus. Today you can see Schröter valley near #Aristarchus much better than yesterday.

#Keppler in the center, #Aristarchus in the upper left (the brightest part of the moon) and the Schröter valley behind.

I love the Aristarchus region. For the longest time I thought there were two rills trailing off from the Crater. I finally realized that one was actually shadow cast by a difference in terrain height.
Here's a shot of #Aristarchus taken with my #ETX90 some years ago.
