Guess the Astronomer!
Eight questions matching famous astronomers to their discoveries β from sunspots to galaxies. How many can you get right?

I discovered that sunspots were depressions and not "clouds" on the surface of the Sun.

I discovered 4 moons of Saturn: Tethys, Dione, Iapetus, and Rhea

Herschel discovered Uranus in 1781. Who holds the record for observing Uranus before then, but completely failed to recognize it as a planet 12 times?

I discovered a planet, which then wasn't a planet, but is now a planet again.

I discovered Proxima Centauri, the closest star to the Sun.

My observations of the timing of eclipses of Io proved that light travels as a finite speed.

Until my discovery, it was thought we couldn't know what stars were made of!

I solved a long-standing mystery about Saturn's rings. I proved they couldn't be a solid or liquid sheet without breaking up under gravity, and instead must be countless, tiny particles orbiting the planet.
