03. Why Is the Sun Hot?

Country Available: Canada

Bob MacDonald

How are stars made, and what makes them so hot? We take a short trip around the Sun so we can answer these questions. In the process we explore dark sunspots, bright solar flares, orangey prominences, and the invisible solar wind. Through the eyes of a space observatory called SOHO, we can view incredibly energetic spots and flares as they actually occur. We peer inside the sun to see how it moves like a giant pot of boiling soup. We can even sail in space on the power of sunlight using a huge plastic sheet as big as a small town. Getting to know the Sun helps us to understand how other stars work, too. We have to understand the sun today because eventually it will burn out, swell up and swallow our entire planet. Enjoy that sunshine while it lasts!
