An Improved Model for That Pesky Zodiacal Dust

The Solar System’s interplanetary dust (called zodiacal dust) can be a source of noise in infrared and optical observations, but it also holds information about the recent history of the Solar System. This new and improved model of the zodiacal dust reveals the relative contributions to the dust by asteroids, comets, and interstellar dust.
