The reason for the high temperatures is unknown but thought to be related to the rapidly changing magnetic field loops that channel solar plasma.

其高温的原因至今是个未解之谜，但是人们认为这是与联通太阳的等离子体的快速变化的磁场循环有关。

Earlier this year, NASA's Solar Dynamics Observatory caught a glimpse of a huge snakelike tendril of magnetic plasma on the sun, extending hundreds of thousands of miles across the surface.

年初，美国宇航局(NASA)的太阳动力学观测卫星捕捉到太阳上磁场等离子体巨蛇般的卷须状物，它沿太阳表面绵延数十万英里。

For a sunspot to form on the solar surface, the magnetic field needs to attain a certain strength to push the surface plasma aside, exposing the solar interior as a cool spot — a sunspot.

在太阳表面，磁场强度必须强到能推开表面的等离子体，将温度较低太阳内部的暴露在外，形成一个太阳黑子。

Solar storms are violent eruptions on the sun that send a wave of charged particles, called plasma, into space at the speed of more than one million miles per hour.
