A team of scientists travelled to Svalbard to observe the solar eclipse using an array of instruments . They studied the sun 's corona , plasma around the sun that can only be seen during a total eclipse . They hope to work out why the corona is 3,600,000 times hotter than the surface , something that remains a mystery . With the experiments successful , they are now looking at their data , which includes measurements of radiation .
