What is an eclipse? An eclipse occurs any time something passes in front of the Sun, blocking its light. This can be the Earth or the Moon.

Is there more than 1 kind of eclipse? Yes!! There are lunar and solar eclipses. Lunar Eclipse- When the Earth casts a shadow on the moon, causing the moon to go dark. Earth comes between the Sun and the Moon and casts a shadow on the Moon Solar Eclipse- When the Moon casts a shadow on the Earth, causing the sun to go dark. The Moon comes between the Sun and Earth and casts a shadow on part of Earth

Lunar Eclipses The Earth moves between the Sun and the Moon, blocking th Sun’s light, and causing the moon to glow red.

Total Lunar Eclipse – when the Moon passes completely into the Umbra, or total shadow of the Earth.

Penumbral Lunar Eclipse – When the moon passes only through the penumbra, or partial shadow. They are barely visible.

Total Lunar Eclipse – when the Moon passes completely into the Umbra, or total shadow of the Earth.

Penumbral Lunar Eclipse – When the moon passes only through the penumbra, or partial shadow. They are barely visible.

Total Solar Eclipse – can only occur if you are at the exact spot within the moon’s umbra (which isn’t very big).

Partial Solar Eclipse – Visible if you are in the penumbra of the shadow. Only some of the moon will be shadowed.

Why Don’t We See Lunar Eclipses More Often? Well, lunar eclipses don’t happen everyday because the Moon’s orbit is tilted. So, during most months, the Moon is above or below the Earth.

Select the photo that demonstrates what happens when the moon is directly between the sun and Earth. The side facing the Earth is in darkness.
