Chemical composition of dust from beyond the solar system analyzed

A dust detector on the Cassini space probe — known as the cosmic dust analyzer (CDA) — has identified several extremely rare and minuscule particles of interstellar dust from outside our solar system, and examined their chemical composition. Surprisingly it turns out that the different dust particles are very similar in composition and have collected the whole element mix of the cosmos. The experts therefore suspect that dust is continually destroyed, reformed and thereby homogenized in the “witch’s cauldron” of outer space.
