Infrared light, you can think of it like heat radiation.

红外线，你可以把它想象成热辐射。

It enters the atmosphere and acts like a blanket around the planet, which means heat radiation can't escape, and the temperature increases.

它进入大气层，像毯子一样包裹着地球，这意味着热辐射无法逃逸，温度就会升高。

Down below, uranium is getting split apart and releasing a bunch of heat, radiation, and high-speed particles, like negatively-charged electrons, and their positively-charged counterparts, known as positrons.

在下面，铀正在分裂，释放出一堆热、辐射和高速粒子，比如带负电荷的电子和带正电荷的电子，称为正电子。

When we see it edge-on the thick dust in the disk blocks the intense highest-energy light, but we do see lots of infrared as the radiation from the disk heats up clouds of dust around it.

当我们看向它的边缘时，在圆盘上的厚尘埃阻挡了强烈的最高能量的光，但我们确实看到了大量的红外线，因为来自圆盘的辐射加热了它周围的尘埃云。
