In January 1610, Galileo Galilei discovered four moons orbiting Jupiter (Io, Europa, Ganymede, and Callisto) using a homemade telescope, providing the first observational evidence that Earth is not the center of the universe and challenging the geocentric model that dominated scientific thought at the time.

Galileo Saw Jupiter's Moons Before Anyone Knew What a Telescope Was #Shorts #SpaceAdded:
In January 1610, Galileo pointed a homemade telescope at Jupiter and spotted four tiny lights.
He watched them for four nights.
They moved.
They were orbiting Jupiter, not Earth.
That was a problem.
Because at the time, everyone believed everything in the universe orbited Earth.
These four moons, [music] Io, Europa, Ganymede, and Callisto, were the first proof that Earth wasn't the center of everything.
One observation, four nights, [music] and a truth that the church would put him under house arrest to suppress.
We still call them the Galilean moons.
Follow for more facts that rewired history.
