A solar eclipse is a celestial phenomenon when the Moon passes between the Earth and the Sun in its orbit.
Solar eclipses only occur during the New Moon phase, and solar eclipses can be total or partial, depending on where you’re viewing them. Eclipses happen because the size of the Moon and its distance to the Sun are in just the right measurements so that when the Moon passes between the Earth and the Sun, it blocks out the Sun completely (how freakin’ cool is that?!).
A total solar eclipse (when the Sun is completely covered) occurs somewhere on earth around every 18 months. Depending on the Moon’s orbit and where the eclipse is being observed, partial solar eclipses and annular solar eclipses can also occur. Solar eclipses play an important part when studying astrology, indicating the end of one cycle and the beginning of another, depending on the Sun sign and astrological house in which they fall in your birth chart.
