Tiny dust particles in space are the seeds of life

Tiny dust particles in space are the seeds of life Dr Stefan Reissl and Prof Dr Ralf S. Klessen introduce tiny dust particles in space, the seeds of life, in this intriguing field of astronomy research. Life on Earth owes its existence to the presence of tiny dust particles in space. These particles are born in the atmospheres of giant, ageing stars and carried into space by the stellar winds of their hosts. Through countless collisions and sticking processes, the small grains grow into larger and more complex aggregates, which may eventually become pebbles, rocks, and finally planets.
