What was the publication titled in which Galileo announced his discovery of Jupiter's satellites?
Answer
Sidereus Nuncius
Galileo Galilei published the findings of his groundbreaking observations, including the discovery of the four moons orbiting Jupiter, in a seminal work titled Sidereus Nuncius. This Latin title translates to 'Starry Messenger' in English. The publication caused significant upheaval in established scientific thought because the visual proof of objects orbiting a body other than Earth directly contradicted the prevailing geocentric Ptolemaic model of the universe, thereby providing powerful evidence supporting the heliocentric view.
