Why Does The Sun Shine?

(专辑： Here Comes Science - 2009)

The sun is mass of incandescent gas, a gigantic nuclear furnace
Where hydrogen is built into helium at a temperature of millions of degrees
Yo ho it's hot, the sun is not a place where we could live
But here on earth there'd be no life without the light it gives

We need its light, we need its heat, we need its energy
Without the sun, without a doubt, there'd be no you and me
The sun is mass of incandescent gas, a gigantic nuclear furnace
Where hydrogen is built into helium at a temperature of millions of degrees

The sun is hot
It is so hot that everything on it is a gas
Iron, copper, aluminum and many others
The sun is large
If the sun were hollow, a million earths could fit inside
And yet the sun is still only a middle-sized star

The sun is far away
About 93,000,000 miles away, and that's why it looks so small
And even when it's out of sight, the sun shines night and day

The sun gives heat, the sun gives light, the sunlight that we see
The sunlight comes from our own sun's atomic energy

Scientists have found that the sun is a huge atom-smashing machine
The heat and light of the sun come from the nuclear reactions
Of hydrogen,carbon, nitrogen and helium

The sun is mass of incandescent gas, a gigantic nuclear furnace
Where hydrogen is built into helium at a temperature of millions of degrees
