Are you feeling the heat? ☀️ What we learn about the sun depends on what kind of light wavelength we use to observe it. Our home star formed about 4.6 billion years ago when a dusty cloud of gas collapsed and began to generate energy. Composed of hot, electrified gas called plasma, the sun accounts for 99.86% of the mass of the solar system. It’s shown here as a composite of three images taken in 2015, soon after its solar maximum. This poster was supported by the National Geographic Society and appeared as a supplement to National Geographic magazine’s September 2021 issue.
