Lunar eclipse tonight!




Hi guys,
Tonight's gonna be a good night! We have a lunar eclipse coming!

Wait a second, teacher... Eclipse? Isn't that awful book with vampires and werewolves and a brainless plot?

Noooo! Eclipse is much more than that! Here, let me show you:




Eclipse (ĭ-klĭps')


Eclipse is the partial or total blocking of light of one celestial object by another. An eclipse of the Sun or Moon occurs when the Earth, Moon, and Sun are aligned. ◇ In a solar eclipse the Moon comes between the Sun and Earth. During a total solar eclipse the disk of the Moon fully covers that of the Sun, and only the Sun's corona is visible. ◇ An annular eclipse occurs when the Moon is farthest in its orbit from the Earth so that its disk does not fully cover that of the Sun, and part of the Sun's photosphere is visible as a ring around the Moon. In a lunar eclipse all or a part of the Moon's disk enters the umbra of the Earth's shadow and is no longer illuminated by the Sun. Lunar eclipses occur only during a full moon, when the Moon is directly opposite the Sun.

Pretty cool, huh?


Your teacher will probably be inside the classroom when this happens, so why don't you take some pictures and send them for us? I'd love to see it.

Have a nice week!

xoxo,
teacher Bel
