Clouds of interstellar dust and gas, here in the region 'Cygnus-X' in the Swan constellation. Image: ESA - Astrophysicists prove that dust particles in space are mixed with ice Light The matter between the stars in a galaxy - called the interstellar medium - consists not only of gas, but also of a great deal of dust. At some point in time, stars and planets originated in such an environment, because the dust particles can clump together and merge into celestial bodies. Important chemical processes also take place on these particles, from which complex organic - possibly even prebiotic - molecules emerge. However, for these processes to be possible, there has to be water. In particularly cold cosmic environments, water occurs in the form of ice. Until now, however, the connection between ice and dust in these regions of space was unclear.
