Solar eclipse occur when the Moon gets between the Earth and the Sun. This causes the Moon to cast a shadow onto Earth.
A solar eclipse occurs when a portion of the Earth is immersed in a shadow cast by the Moon, which fully or partially blocks sunlight. This happens when the Sun, Moon, and Earth are aligned. Such alignment coincides with a new moon , indicating the Moon is closest to the ecliptic plane.
Solar Eclipse June 21: Watch the Visuals
An annular solar eclipse happens when it is New Moon, the Moon is at a lunar node, so the Earth, the Moon, and the Sun are aligned in a straight line. The Moon is near its farthest point from Earth, called apogee, so the Sun’s outer edge remains visible as a ring of sunlight. The first solar eclipse of the year will occur today.

Secrets Behind Solar Eclipse
The Sun is completely blocked in a solar eclipse because the Moon passes between Earth and the Sun. This completely blocks out the Sun’s light. However, the Moon is about 400 times smaller than the Sun. The solar eclipse is dangerous because the Sun outputs more power than our eye is designed to handle, and exposing our eye to that kind of power can damage the retina. And in a nutshell, solar eclipses are dangerous because the Sun can come out from behind the Moon and “surprise you” before you have a chance to look away.
Today’s annular solar eclipse only in 19 years the Moon comes in between the Earth and the Sun, leaving the Sun’s visible outer edges to form a “ring of fire” or annulus around the Moon.
