The first Thanksgiving night sky: What did the Pilgrims see when they looked up?


Oct 22, 2019
Interesting comment in post #2. Let me see, Copernicus, Tycho Brahe, Galileo telescope observations of the tiny lights moving around Jupiter, later Kepler, followed by Isaac Newton. 1620-1621 is well into the telescope observation times and heliocentric solar system model. Did Galileo say he could see the tiny lights moving around Jupiter because they were connected to a solid dome?

The dome concept is popular in flat earth teachings today. Here is a 14 page arXiv paper that could help detailing the astronomical investigations into the distance between Earth and the Sun, i.e. the astronomical unit. Much study was underway even before Copernicus and Galileo, I did not see an indication that these folks held to the flat earth view of the dome sky :) Six stages in the history of the astronomical unit,
