The Sun

매일 뜨고 지는 태양을 과학자들이 왜 연구하나?? 했는데..

태양이 언젠가는 사라질 별이라니..

수십억년 후의 일이지만.. 생각하니 좀 무서운 생각이 드네요.

이번 요약엔 태양이 사라지면 어떨지? 제 생각도 조금 넣어봤어요.

[요약]

The Sun is our nearest star and a big ball of gas, which is made up of 90% hydrogen, 8% heliem and things like iron, carbon, oxygen, nickel.

The main gas, hydrogen, provides all the sun's energy as a result of gas explosions or nuclear reactions in its core.

It takes a hundred thousand years for the energy to reach the sun's surface

whereas it takes only eight minutes for the energy from the sun to reach the Earth.

The sun's core is 5 million degrees Celsius and its surface is 5500 degrees Celsius.

The sun came into being around four and a half billion years ago and is expected to stay for as long again.

But the sun will be a red giant star, which means it will get hotter and make the Earth end up burning up.

What if the sun disappeared?

We wouldn't be alive because we will have no heat and light energy from the sun.

The temparature would drop down 100 degrees below zero and

there would be no food, no animals and surely no human beings.

The gravity of the earth would change.

Besides the magnetic force between the sun and the earth would change and the earth would drift in the space.

I hope the sun will stay stable there as long as possible for our planet.

태양의 구조는 이미지를 검색해서 따라 그려봤어요.

색연필로 색칠도 해봤는데... 서툴지만, 태양의 모습을 살려보려고 애썼네요. ㅎㅎ

우연히 찾은 동영상인데

우리 아이들이 보면 좋을 것 같아서 올려봅니다.
