Thanks to Webb, the unseen are seen
One of our galaxy’s biggest mysteries is the star-forming region called Sagittarius C, located about 300 light-years away from the Milky Way’s supermassive black hole. There are an estimated 500,000 stars shining in the image, varying in size and age. Among these is a protostar cluster, or dense masses of dust and gas that are still developing and turning into full-fledged stars. It is also known that there is a huge protostar at the center of the cluster with a mass more than 30 times that of the Sun.
The research team says the galactic center is close enough for JWST to study individual stars. This allows unprecedented information to be collected about how stars may form in this region compared to other parts of the galaxy. Examining the center of the Milky Way with Webb can provide information about how many stars are forming there and whether massive stars are more likely to form near the galactic center rather than in the galaxy’s spiral arms. The research team is also interested in needle-like structures arranged without any order in ionized hydrogen.
