【The sun】

When looking the sun through a telescope,we can see something black on the surface of the sun.It's a sunspot 黒点.☀

The sun is an enormous ball made of gas,its pressure causes nuclear fusion inside the ball,and an energy of light and heat is being released.☀

The energy creates a gigantic magnetic field at the same time,so the sun itself becomes a tremendous magnet.☀

The magnetic field appears on the surface of the sun.It's the sunspot.☀

The sunspot is lower than around it with regard to the temperature,so it looks black relatively.While it looks small,its scale is equivalent to two earths.🌏

The sun repeats lively activities in about 11 years of period,the sunspot frequently emerges on the sun then.☀

A phenomenon of huge explosion sometimes happens around the sunspot.We call it flare.🔥

Then enormous flare which is correspondent to several earths raises.The earth's magnetic fields are so greatly influenced by the phenomenon that a Dellinger fadeout デリンジャー現象 occurs.🔥
