NASA's James Webb Space Telescope captured a blowtorch of seething gasses erupting from a volcanically growing monster star in this image released on Sept. 10, 2025. Stellar jets, which are powered by the gravitational energy released as a star grows in mass, encode the formation history of the protostar. This image provides evidence that protostellar jets scale with the mass of their parent stars-the more massive the stellar engine driving the plasma, the larger the resulting jet.
