SOLAR ECLIPSES

SOALR ECLIPSE :

WHAT ARE SOLAR ECLIPSES?

A solar eclipse is a spectacular sight and a rare astronomical event. Each one is only visible from a limited area.
Today i.e on 21st June many locations will see a rare solstice annular solar eclipse on the same day as the June solstice.
This will happen only twice this century , in 2020 and on June 2039.


An eclipse of the sun happens when the new moon moves between the sun and Earth, blocking out the Sun's rays and casting a shadow on parts of the Earth.

The Moon's shadow is not big enough to engulf the entire planet , so the shadow is always limited to a certain area .
This area changes during the course of the eclipse because the Moon and Earth are in constant motion.
Earth continuously rotates around its axis while it orbits the Sun, and the Moon orbits the Earth. This is why solar eclipses seem to travel from one place to another.

TYPES OF SOLAR ECLIPSES:

  1. PARTIAL SOLAR ECLIPSES : It occurs when the Moon only partially obscures the Sun's disk and casts only its Penumbra on Earth.
  2. ANNUAL SOLAR ECLIPSE: It takes place when the Moon's disk is not big enough to cover the entire disk of the Sun , and the Sun's outer edges remain visible to form a ring of fire in the sky. An annular eclipse of the sun takes place when the Moon is near apogee , and the moon's antumbra falls on the Earth.
  3. TOTAL SOLAR ECLIPSE: It happens when the Moon completely covers the Sun , and it can only take place when the Moon is near perigee , the point of the Moon's orbit closest to Earth. We can only see a total solar eclipse if we are in the path where the Moon casts its darkest shadow , the umbra.
  4. HYBRID SOLAR ECLIPSE : It is also known as annular - total eclipses, are the rarest type. They occur when the same eclipse changes from an annular to a total solar eclipse , or vice versa, along the eclipse's path.

For a solar eclipse to take place , the Sun , the Moon , and the Earth must be aligned in a perfect or near perfect straight line. this happens around New Moon every Lunar month.

PROTECT YOUR EYES :
Never look directly at the Sun , eclipsed or otherwise , without any protective eyewear. The Sun's UV radiation can burn the retinas in your eyes leading to permanent damage or even blindness.

The best way to safely watch a total solar eclipse is to wear protective eclipse glasses or to project an image of the eclipsed Sun using a pinhole projector.
