Observing the solar system

  • The only star in our solar system, the sun, has many parts

    Core – central region that produces enormous amounts of energy. Nuclear fusion occurs here – that is when hydrogen atoms join to form Helium

    Photosphere – inner layer of the sun

    Chromosphere – middle layer of the sun

    Corona – outer layer of the sun – looks like a halo around the sun

    Sunspots – areas of gas on the sun that are cooler than the gases around them

    Prominences – reddish loops of gas that link sunspot regions

    Solar Flare – gas eruptions sent out into space
