Aside from this cosmic tarantula, NASA’s James Webb Space Telescope captured a colorful cosmic knot from the early universe. More specifically, a cluster of gigantic galaxies in the process of formation around an extremely red quasar.
What you’re looking at here is SDSS J165202.64+172852.3, an “extremely red” quasar that existed in the very early universe approximately 11.5 billion years ago. This cosmic phenomenon is a rare, incredibly luminous type of active galactic nucleus (AGN) and one of the most powerful known galactic nuclei that’s been seen at such an extreme distance. Astronomers believe that this quasar’s extreme emission could cause a “galactic wind”, pushing free gas out of its host galaxy and possibly influencing future star formation in that area of the universe.

There are few galaxy protoclusters known at this early time. It’s hard to find them, and very few have had time to form since the Big Bang. This may eventually help us understand how galaxies in dense environments evolve… It’s an exciting result,” said Dominika Wylezalek, astronomer from Heidelberg University in Germany, who led the study into this quasar.
