The Corona.
Because they wanted to observe them
They don't look directly at the sun. They use special cameras and telescopes with filters over them in order to avoid damaging their eyes.
You can study the gravitational force the sun excerts on light of other stars by comparing their position in daytime during the eclipse and a night. Einstein's General Theory of Relativity was proved in this way.
Scientists can use them to study the early solar system.
the corona ________________________ Which isn't exactly true, or at least, not any longer. The spooky, glowing halo around the Sun during a total eclipse seems bright only in comparison to the blackness of space; compared to the brilliance of the Sun itself, the corona is almost nothing. But because scientists wanted to study the solar corona and solar eclipses are very short and happen at difficult-to-get-to locations, they wanted a way to create an artificial eclipse so they could study it all the time. This was the inspiration for the coronagraph, a special telescope that blots out the disk of the Sun itself and allows astronomers to examine the corona whenever they like.
It's not as important as it once was. There was a time when the only time scientist could study the sun's corona was during a total eclipse of the sun. With today's modern technology, scientists can study the solar corona by creating a solar eclipse with their telescopes.

During a solar eclipse, the moon blocks most of the light coming from the sun to the Earth. This allows an astronomer or anyone to see the remaining with less interference or distraction caused by the overwhelming amount of light normally emitted by the sun. For hundreds of years, astronomers have gone all over teh world to locations where the moon casts it shadow on the Earth so they can view the eclipse. There is a long list of solar features which are possible to observe and study during a solar eclipse, but a common example is the corona, the sun's outer atmosphere. The corona has much structure and can be studied in much greater detail when seen on edge during a solar eclipse.
the corona(one of the layers of the sun's atmosphere) of the sun becomes visible, which enables scientists to study it and gain a better understanding of the sun

Solar energy is renewable. It helps in saving exhaustible resources.
Ignoring the many space probes that can now study the sun around-the-clock, the answer is at the moment of totality during a total solar eclipse.
