The Hubble Space Telescope deals primarily with visible wavelengths, but anyone who remembers there high school chemistry class knows that visible wavelengths are only a small portion of a large spectrum of wavelength ranges. For example infrared wavelengths are longer, and therefore have lower energy than visible. And X-Ray wavelengths are shorter and have higher energy amounts. Just think, you wouldn’t want to have someone blasting you with X-Rays for more than a minute or so. Why do you think you’re left alone in a dark room whenever you go and get an X-Ray? It’s because the nurses don’t want to end up with cancer, no matter how high the workers compensation might be.
Well, in addition to Hubble, the infrared and X-Ray space telescopes go by the names Spitzer and Chandra, respectively. Recently astronomers have combined these two space telescopes’ data to produce some magnificent photos, which allow astronomers a simultaneous look at both the infrared and X-Ray wavelengths of an object. How cool is that?
