UV Radiation from Massive Stars Shapes Nearby Planetary Systems

Feb 29, 2024 by News Staff

For decades, astronomers have known that the powerful light emitted by massive stars can disrupt the swirling planetary disk of dust and gas around young...

This image taken by Webb’s Near-Infrared Camera shows a part of the Orion Nebula known as the Orion Bar. It is a region where energetic ultraviolet light from the Trapezium Cluster -- located off the upper-left corner -- interacts with dense molecular clouds. The energy of the stellar radiation is slowly eroding the Orion Bar, and this has a profound effect on the molecules and chemistry in the protoplanetary disks that have formed around newborn stars here.
