High-frequency light is useful. The higher the frequency of light, the shorter its wavelength—and the shorter the wavelength, the smaller the objects and details the light can be used to see.

Scientists map sulfur residue on Jupiter's icy moon Europa

A Southwest Research Institute-led team used the Hubble Space Telescope to observe Jupiter's moon, Europa, at ultraviolet wavelengths, filling in a "gap" in the various wavelengths used to observe this icy water world. The ...
