Watch Extreme Environments - Sun

The Sun provides light and warmth that makes our Earth inhabitable. A yellow dwarf star that fuses hydrogen atoms into helium and releases huge amounts of energy in the process, the Sun serves many functions. Used as an accurate basis for calendars, worshipped as a God and celebrated at Stonehenge, the Pyramid of the Sun, Inti Raimi and Olympia, the sun is crucial to our existence. Scientists are using technological advancements such as the Solar & Heliospheric Observatory (SOHO) to better understand the Sun.
