Unveiling Mars' secrets: Scientists use MAVEN's Imaging Ultraviolet Spectrograph (IUVS) instrument to capture ultraviolet images of Mars. The IUVS measures wavelengths outside the visible spectrum, rendering them visible by assigning brightness levels to different ultraviolet ranges. This colorization technique highlights ozone, clouds, haze, and surface details. (NASA)
