A stellar wind blows gas away from a cradle of planets. It is happening around a star located in the Orion nebula, about 1500 light years away, and the process will continue for about a million years.
Usually, similar phenomena occur when protoplanetary disks, i.e. the disks of gas and dust from which planets will be born, are heated by X-rays or ultraviolet rays, which increase the temperature of the gas and cause it to escape from the system. The discovery, published in the journal Science, is due to research coordinated by the group of Olivier Berne', astrophysicist and planetary scientist from the French University of Toulouse.
