A summary of the physical and chemical nature of life must begin,not on the Earth,but in the Sun; in fact,at the Sun's very center.It is here that is to be found the source of the energy that the Sun constantly pours out into space as light and heat.This energy is librated at the center of the Sun as billions upon billions of nuclei of hydrogen atoms collide with each other and fuse together to form nuclei of helium,and in doing so,release some of the energy that is stored in the nuclei of atoms.The output of light and heat of the Sun requires that some 600 million tons of hydrogen be converted into helium in the Sun every second.This the Sun has been doing for several thousands of millions of year.
the nuclear energy is released at the Sun's center as high-energy gamma radiation,a form of electromagnetic radiation like light and radio waves,only of very much shorter wavelength.This gamma radiation is absorbed by atoms inside the Sun to be reemitted at slightly longer wavelengths.This radiation ,in its turn is absorbed and reemitted.As the energy filters through the layers of the solar interior,it passes through the X-ray part of the spectrum eventually becoming light.At this stage,it has reached what we call the solar surface,and can escape into space without being absorbed further by solar atoms.A very small fraction of the Sun's light and heat is emitted in such directions that after passing unhindered through interplanetary space,it hits the Earth.

简要介绍了物理和化学性质的生活必须开始,而不是在地球上,但在太阳;事实上,在Sun公司的非常中心.正是在这里,是要找到来源的能源,太阳不断涌入进入太空的光和热.这就是librated能源为中心的太阳时数十亿数十亿核氢原子碰撞互相融合在一起,形成的氦原子核,并在此过程中,释放一些能量,是储存在原子的原子核.输出的光与热的太阳需要大约600万吨的氢转变成氦的孙每一秒.这太阳已经做了数以千计的数以百万计的一年.
核能释放在太阳的中心高能伽玛辐射,一种形式的电磁辐射光,像无线电波,只有非常短的波长.这伽马辐射是由原子吸收太阳内部要在较长的波长.这种辐射,在其又是吸收和reemitted .由于能源通过过滤层的太阳内部,它通过X -射线的一部分频谱最终成为轻.在这个阶段,已经达到我们所说的太阳表面,并能逃脱进入太空,而进一步吸收太阳能原子.有很小一部分太阳的光和热排放等方向,经过畅通无阻地通过行星际空间,它击中地球.
