2. The Moon
Man in the Moon
Imaginary image seen on the surface of the moon.
Drawn in the dark maria (sea) and lighter highlands of the moon.
Myths about image are found in many cultures.

3. Rotation and Revolution
Why do we always see the same side of the moon?
Moon’s rotation on its axis: 27.3 days
Moon’s revolution around Earth: 27.3 days
Revolution takes the same amount of time as rotation, so we always see the same side of the moon facing Earth.

4. Moon Phases and Eclipses

5. Moon Phases
Moon Phases -the different forms the moon takes on when viewed from Earth.

6. Phases depend on the relative positions of the Earth, Moon, and Sun.

7. We only can see the “day” side of the moon when it reflects the sunlight.

8. New Moon Occurs when the moon is between the Earth and Sun.
The lighted half of the moon is facing the Sun, the dark half is facing Earth.

38. Eclipses

39. Eclipses Caused by the revolution of the moon.
Occurs when the moon blocks the sunlight from reaching the Earth or vice-versa.

40. Solar Eclipse
Occurs when the moon moves directly in between the Earth and Sun and casts its shadow on the Earth.
What phase is the moon?
New Moon

41. Shadow of an eclipse Umbra-Darkest part of the shadow (total eclipse)
Penumbra- Lighter, surrounding part of shadow (partial eclipse)

43. October 23rd 5:45pm Partial Solar Eclipse

45. Solar eclipse-notice the CME’S around the sun.
Satellite photo of solar eclipse shadow on Earth, notice the umbra and penumbra areas.

47. Lunar Eclipse
Occurs when the Earth moves directly between the Sun and the Moon. The Earth’s shadow falls on the Moon.
What phase is the moon?
Full Moon

48. Sometimes, when the moon is in the umbra, sunlight is bent through Earth’s atmosphere causing a red color on the moon.

50. Lunar Eclipse from the Moon

51. Will I see an eclipse?

52. The moon’s orbit is tilted so eclipses are rare events.
