Corona sun's outer atmosphere
chromosphere deep red layer under corona, only visible during a solar eclipse
photosphere gases are thick enough to see on visible surface
convective zone hot gases rise, cool and sink
radiative zone very dense that light may take millions of years to pass through
core where energy is produced through nuclear fusion
sunspots areas which are a little cooler on the sun
solar flares giant storms on the surfaces of the sun creating light shows
auroras light shows
constellations sections of the sky that contain 1 of 88 imagined pictures made by stars in the night sky
