During a solar eclipse, the moon blocks most of the light from the sun, this gives scientists the perfect opportunity to study the sun's corona. This is the topmost part of the sun that has the burning gasses. If scientists have a good look at this region during the solar eclipse, they will better understand the sun and the stars in general.
"Its shape changes all the time, so we only get these high-resolution glimpses for two or three minutes every year or two," said Jay Pasachoff The lead scientist studying the Corona. "Each time is like going to the seventh game of the World Series with the score tied in the ninth inning."
This phenomenon has made Indonesia a tourist destination, with hotels booked since 2014 in readiness for this. Tourists or rather 'eclipse-chasers' are excited due to most of the Indonesian islands will be completely dark.
The next solar eclipse will be viewed in the US in April 2017. This will last approximately two minutes and forty seconds. It will not be as long as the Indonesian one, but scientists are banking on the fact that since it will be in the United States, it will be viewed by more equipment. This will lead to more data collection for studies.
