The discovery of sunspots is a bit more complex than a single person. Here’s a breakdown:
- Galileo Galilei (C): He was likely one of the first astronomers to observe sunspots telescopically around 1610, though his records didn’t start until 1612.
- Thomas Harriot: He also made telescopic observations of sunspots in December 1610, with documented notes.
- Johannes Fabricius: He and his father David Fabricius independently observed sunspots in March 1611, but Johannes was the first to publish about them in late 1611.
Therefore, while Galileo is a famous name associated with sunspots, credit for the discovery could be given to C. Galileo, Thomas Harriot, or Johannes Fabricius.
