Freshly emerging stars generate jets that collide with surrounding cosmic gas and dust, resulting in powerful shockwaves, according to Webb.
The James Webb Space Telescope has provided a stunning glimpse into the birthplace of new stars, revealing the hidden treasures within the Serpens Nebula. This young reflection nebula, approximately 1-2 million years old, is home to a dense cluster of newly forming stars, around 100,000 years old.
The telescope's powerful capabilities have allowed it to see through the cosmic cloud, revealing extremely young stars and their outflows. Some of these outflows, previously obscured by thick dust, were found to be aiming in the same direction.
The image captures the jets of gas hurtling outwards from newborn stars, seen as bright red clumpy streaks. These streaks are shockwaves caused as a jet hits the surrounding gas and dust. The red colour in the image indicates the presence of molecular hydrogen and carbon monoxide.
The discovery of a group of protostellar outflows offers new insight into the mechanisms by which stars are born in cosmic clouds. As an interstellar gas cloud collapses under the force of gravity, it spins more rapidly and forms a disc of material around the young star. Swirling magnetic fields launch some of the material into twin jets that shoot outwards into space, perpendicular to the rotating disc.
The area of Serpens North within the Serpens Nebula is only visible with the James Webb Space Telescope. The image shows filaments and wisps of varying colours, representing reflected starlight from still-forming protostars within the cloud. Some of these stars may grow to the mass of our Sun.
The author of the scientific article on the James Webb Space Telescope and the discovery of specific outflows from young stars in the Serpens Nebula region is not explicitly stated in the search results. However, the analysis involves JWST NIRSpec observations of protostellar cores in Serpens, but no individual researcher's name is mentioned in the available sources.
This groundbreaking discovery marks a significant step forward in our understanding of star formation and the complex processes that shape our universe.
