Dusty worlds like the desert planet Arrakis from Dune may be common throughout the galaxy. Some of these worlds, harboring large quantities of dust in their atmospheres, maybe likely places to find life, a new study concludes. However, these same dusty conditions also make finding evidence of life on these worlds more challenging for astronomers. Researchers modeled three forms of exoplanets, each with varying amounts of dust in their atmosphere. The study found that dusty atmospheric conditions could insulate a planet, increasing the range of distances at which life could form, making the development of life more likely on these planets, if…
