Our Sun

  •  The Sun is made up of gas and dust that began to fall into its own force of gravity and ignite under pressure causing a nuclear fusion at 1 million degrees.
  • The surface of the sun is 10,000 degrees.
  • As it grew, the baby sun became hotter and hotter.
  • Scientists say the sun was born through a vast cloud of dust around 5 billion years ago.
  • The Sun is so large that the earth could easily fit inside the sun a million times

Like A Flower?

  • There are spots in the sun that are slightly cooler then other spots. These are known as sun spots.
  • The spots are slightly darker then other spots because they are cooler.
  • People have to use special telescopes with filters and other things to be able to see the cooler spots on the surface of the Sun.
  • Spots come and go, sometimes there are a lot and sometimes there are not.
  • This happens over 11 years and it is called the Saros Cycle.

Solar Flares

  • In times of high solar activity, the sun releases massive amounts of gas and plasma into its atmosphere. 
  • These flares can be really small or HUGE and have explosions like bombs. 
  • These flares can be so powerful that they can cause our satellites that go around our earth to not work right. 
  • They also create beautiful light shows known as Aurora Borealis.
