David Jamieson delves into the revolutionary discoveries made by Galileo in the early 17th century.

Galileo unearthed Jupiter's moons, Venus's phases, and lunar landscapes using his groundbreaking telescope. However, hidden within his logbooks lie tantalising clues: the sighting of a mysterious "fixed star," now recognised as the planet Neptune, observed long before its official discovery.

This talk explores the possibility that Galileo may have recognised Neptune's planetary nature, potentially marking humanity's first discovery in millennia. Join us as we unravel the enigma of Galileo's observations and their profound implications for our understanding of the cosmos.
