Document Summary
Annular eclipse (partial eclipse): the moon is slightly farther away- apogee (because its orbit is elliptical) so you can only see a thin ring a. b. Historically, they provided the first test to einstein"s theory of relativity- space is warped. Mass warps space and time so the apparent position of stars is different from the actual position i. ii. The closer the starlight passes to the sun, the greater the separation between the apparent and true positions. Lunar eclipse: the earth casts a shadow in space and the full moon passes in that shadow- it appears yellow, orange, and red a. b. c. d. e. f. g. During a lunar eclipse, the earth"s shadow is curved. Earth blocks the sun"s rays, but some of them pass through and are bent to the moon i. The blue, green, and violet molecules are scattered out towards. The brightness of the moon depends on how centrally the moon passes through the shadow.
