词条红外线（IR）

描述: 红外线是一种电磁辐射，波长比可见光长，但比微波和无线电波短。红外线的波长在700纳米到1毫米之间，而可见光的波长在400纳米到700纳米之间。因此，红外线无法通过肉眼看到，只有通过特殊的照相机才能看到。温度在几十开尔文到几千开尔文之间的热体，如太空中的分子云、人体或褐矮星，其电磁辐射的峰值落在红外线区段内。

Infrared Reentry Analysis: Shuttle Orbiter Columbia

图注： A composite image of the Space Shuttle Columbia's reentry, captured by NASA's Kuiper Airborne Observatory. The right hand side of the image was taken in infrared light with the left hand side taken in visible light. The image reveals the intense heating patterns encountered during descent. The temperature scale for the infrared image goes from violet at the coolest end to red at the hottest. We can see here that the wing and tail of the space shuttle are glowing the brightest, indicating that they are the hottest.
