Space is a harsh environment, but some areas are even harsher than others. A star-forming region known as the Lobster Nebula is host to some of the most massive stars in our galaxy. Massive stars are hotter, and therefore emit more ultraviolet (UV) light. That UV light bathes planet-forming disks around nearby stars. Astronomers would expect the UV to break apart many chemical molecules. However, the James Webb Space Telescope has detected a variety of molecules in one such disk, including water, carbon monoxide, carbon dioxide, hydrogen cyanide and acetylene. Such molecules are among the building blocks of rocky planets.
