"Although the ionospheric effects of solar eclipses have been studied for over 50 years many unanswered questions remain".

August 2017 marked the last time all of North America caught a glimpse of a total solar eclipse.

As per Indian Standard Time, the full eclipse will begin at 11:31 pm on July 2 at the first location to see the full eclipse and last till 12:52 am on July 3 at the last location to see the full eclipse. A partial eclipse will be visible to people in Bolivia, Peru, Ecuador, Paraguay, and Uruguay, and parts of Brazil, Colombia, Panama and Venezuela, NASA reported.

According to Space.com, the starting point of the eclipse will be from 4,000 km east-northeast of Wellington, New Zealand, from where it will make the second landfall reaching central Chile. As noted by Forbes, a solar eclipse can provide the platform to study the Sun's characteristics that are usually unseen during daytime.

These types of eclipses happen when the moon's position is too far from the Earth. From there, the total eclipse will travel to the southeast, ending near Chascomús in the eastern Buenos Aires province of Argentina, at 4:44 p.m. local time.

A solar eclipse occurs when the moon passes between the sun and earth and blocks the sun. The corona or the sun's atmosphere is where solar weather and solar winds are prominent.

Total eclipses are relatively rare for a particular spot. In 2018, NASA launched the Parker Solar Probe that took videos and pictures of the sun's surface.

The sun is about to pull a disappearing act.

Northern Chile is known for clear skies, and some of the largest, most powerful telescopes on Earth are being built in the area, turning the South American country into a global astronomy hub.

The museum also has a dedicated app for the total solar eclipse on iOS and Android.

One group, led by Jay Pasaschoff (Williams College) will continue an experiment that stretches back more than 20 years.

If you are in a part of the world where you can directly witness the total solar eclipse or a partial solar eclipse, remember not to see it with naked eyes.

Once the eclipse is over, the next solar eclipse will occur on December 26, 2019, over parts of Asia and Australia. It will, again, be visible from Chile and Argentina.
