What Is Solar Eclipse?

A solar eclipse occurs when a portion of the Earth is engulfed in a shadow cast by the Moon which fully or partially blocks sunlight. This occurs when the Sun, Moon and Earth are aligned. Such alignment coincides with a new moon (syzygy) indicating the Moon is closest to the ecliptic plane. In a total eclipse, the disk of the Sun is fully obscured by the Moon. In partial and annular eclipses, only part of the Sun is obscured.

What Is Total Solar Eclipse?

The total solar eclipse occurs when the new moon arrives between the sun and the earth and emits the umbra on earth, which is the darkest part of the shadow. The moon covers the entire Sun during during a total solar eclipse. A total solar eclipse is only visible in regions which is located in the path of the Moon's umbra. And the ones who are outside the path can see only a partial solar eclipse in which the Moon only blocks a part of the Sun. A total solar eclipse can last for several hours and totality can range from a few seconds to 7.5 minutes, says timeanddate.com.
