bringmetherain · Answer

I think it's B though

tanabugg · Answer

I think it'd be C.

tanabugg · Answer

At first I was thinking it'd be B but i'm thinking C

anonymous · Answer

C sounds like the better answer. It would of been the easiest thing to see with the telescopes they had then.

tanabugg · Answer

Yeah!  Bc they weren't as "high tech" as they are now

anonymous · Answer

Exactly :)

bringmetherain · Answer

"With his telescope, he noticed small dark spots that had never been seen before on the illuminated part of the moon's surface, along with similar light spots in the dark area. He observed that as time passed, these and other spots changed, either getting lighter and eventually disappearing or getting darker and more distinct. The interface between the light and dark sides of the moon was rough and uneven, rather than smooth as would be expected on a perfectly smooth sphere. Galileo also observed that the spots all "have a dark part on the side toward the Sun while on the side opposite the Sun they are crowned with brighter borders like shining ridges." (Sidereus Nuncius, p 41)"
