The Electromagnetic Spectrum Poster

Learn about the different wavelengths in the electromagnetic spectrum, including those that are invisible to the human eye, with this poster, exclusively from Astronomy magazine.

The electromagnetic (EM) spectrum consists of all forms of light. And, as it turns out, most of the universe is invisible to the human eye. Luckily, astronomers can use telescopes to peer into other EM wavelengths — from the radio waves that pierce through dense interstellar dust to the ultraviolet light of stellar nurseries to the gamma rays that stream from supernovae and colliding stars  Learn about the wavelengths, frequencies, and visible spectrum of common (and uncommon) things around us.
