Solar and lunar eclipses

  1. 1. Lunar and Solar Eclipses
  2. 2. What is an eclipse? An eclipse occurs when one object in space blocks an observer from seeing another object in space. From Earth there are two main types of eclipses: solar eclipses and lunar eclipses.
  3. 3. Solar Eclipse A solar eclipse occurs when the Moon passes in front of the Sun causing a shadow to fall on certain portions of the Earth. The eclipse is not seen from every place on Earth, but only from the locations where the shadow falls. From these locations, it appears as if the Sun has gone dark.
  4. 4. There are three main parts of the Moon's shadow during an eclipse called the umbra, penumbra, and antumbra. 1. Umbra :The umbra is the portion of the Moon's shadow where the Moon completely covers the sun. 2. Antumbra: The area of the shadow beyond the point of the umbra. Here the Moon is completely in front of the Sun, but doesn't cover the entire Sun. 3. Penumbra: The area of the shadow where only a portion of the Moon is in front of the Sun. Solar Eclipse
  5. 5. Depending on what part of the shadow you are located in, there are three types of eclipses: 1. Total: A total eclipse is where the Sun is covered completely by the Moon. 2. Annular: An annular eclipse is when the Moon covers the Sun, but the Sun can be seen around the edges of the Moon. 3. Partial: A partial eclipse is when only a portion of the Sun is blocked by the Moon. Types of Eclipse
  6. 6. Never look directly at a solar eclipse. Even though it appears darker, the harmful rays of the Sun can still damage your eyes. Don't Look at A Solar Eclipse!!!
  7. 7. Lunar Eclipse A lunar eclipse occurs when the Moon passes through the Earth's shadow. Lunar eclipses have the same three phases or types as solar eclipses including the umbra (total), antumbra (annular), and penumbra (partial).
  8. 8. Lunar Eclipse Lunar eclipses can be seen by a much larger area of the Earth than solar eclipses. They also can be viewed without special equipment to protect the eyes. Lunar eclipses are not totally dark.
  9. 9. Interesting Facts about Eclipses * The longest that a solar eclipse will last is seven and a half minutes. * The most solar eclipses of any type that can occur on Earth within a year is five. * A total solar eclipse occurs about every 1.5 years. * Animals sometimes become confused and behave strangely during a total eclipse of the Sun.
