Webb Sees a Supercluster of Galaxies Coming Together
- The James Webb Space Telescope has been used to study one of the oldest and most significant star clusters, the Spiderweb protocluster, giving scientists information about how gravity played a different role in shaping star formations than previously thought. Results show undetected galaxies in the protocluster hidden by dust, with observations of hydrogen gas accounting for traces of star formation rate within galaxies. A deep-line survey found 41 new sources, with 17 Pa-beta emitters confirmed as star-forming regions. More observations are expected in the near future to provide confirmation of previous finds.

- Results show undetected galaxies in the protocluster hidden by dust, with observations of hydrogen gas accounting for traces of star formation rate within galaxies.
- These observations revealed the presence of new, previously undetected galaxies in the protocluster that were obscured by dust.
- Deep-line survey found 41 new sources, with 17 Pa-beta emitters confirmed as star-forming regions.
- More than 100 individual galaxies are forming a cluster at the Spiderweb, showing up as a city of galaxies in construction in space.
- The construction of these galaxies is happening due to a smooth production of dust that has been observed rather than from abrupt gravity-driven mergers.
- Future observations with spectroscopic analysis from JWST should back up initial findings and lead to additional confirmation of new members of the Spiderweb protocluster.
- New results will provide researchers with a better understanding of the total star formation rate in the Spiderweb protocluster and the environment's dependence on galaxy formation.
- As is often the case on the journey, more observations are needed to provide new insights and confirm previous observations.
