Riccioli's Almagestum Novum (1651) wasn't just the most comprehensive Astronomy Textbook ever.
It also linked House Grimaldi to French Royal ancestors, pushing the diplomacy that would ally Monaco with France and protect them from Italian Unification.

No Galileo did not prove heliocentrism.
He didn't even claim he had proved it.
The 1st empirical evidence of Earth's motion was Bradley aberration, published 1728.
The myth that Galileo had proved it was started by Voltaire in 1734 in Letter 14 of Philosophical Letters.

Galileo not da Vinci. Although I got the actual time wrong twice today so I may have misspoken. Anyway, having improved telescope technology, he *proved* the heliocentrism that Copernicus had previously established as a theory. And got branded a heretic for his troubles.

Johannes Kepler had the best arguments for Heliocentrism in his time, and continued to be the strongest advocate pretty much until Newton.
This is despite predating Galileo.
Here is a thread explaining Kepler's arguments as presented in Astronomia Nova (1609):

The first substantiated proposal of an exoplanet I'm aware of was in 1783. The star Algol was observed to be of variable brightness by the deaf astronomer John Goodricke.
His collaborator, Edward Pigott, proposed that it must be a planet that orbits the star and frequently occults it.

Spindle Ermine Moth caterpillars... the British equivalent of the silk worm.
These guys have been covering whole trees nearby with webbing.
Spindle Ermines usually will just eat spindle tree leaves, but my ones seem to be very happily munching away on some willow.
