People are good at seeing the wavelengths in the visible range, but other wavelengths of electromagnetic spectrum, like X-rays, ultraviolet and infrared, are invisible to the human eye.
Scientists can learn a lot about a planet, star or galaxy by studying all the different kinds of radiation that come from these objects. So, they need to build special instruments that can read these different wavelengths. But, there's another problem. Most forms of radiation can not get through the Earth's atmosphere. So, how do you solve this problem? |
