A research team led by planetary scientist Hiroki Karyu at Tohoku University has identified meteorite particle accumulation as the source of planetary atmospheric haze.[2] The study, published in Nature Astronomy, found the steady incoming flow of cosmic dust is sufficient to maintain the lower haze layer, matching the particle size distribution recorded by entry probes.[3] The GIMLI research team lists co-investigators from Boise State University, Johns Hopkins University, the Lunar and Planetary Institute and the University of Oslo.[1]
