By doing this, the scientists hope to learn more about the super-heated gases that comprise the solar corona.

Studying CMEs – massive fireballs that blow out of the Sun’s outermost corona layer – is one of the most important scientific objectives of India’s maiden solar mission.

In Cleveland, where eclipse-watchers were graced by clear skies, the Sun's corona was clearly visible, a brilliant halo framing the Moon.

The difference between the speed of the fast and slow solar wind is thought to be due to the different areas of the Sun's corona, the outermost layer of its atmosphere, that they originate from.

A change of host, especially from animals to humans, can greatly facilitate the spread of the virus, as the corona pandemic has emphatically demonstrated.
