Published in The Astrophysical Journal Letters,<\/em> the images present new observations from the telescope in multiple wavelengths.<\/p>\n The discovery will expand on our knowledge of how galaxy clusters in the early Universe came together and formed the cosmic web we see today.<\/p>\n A red quasar is a special type of active galactic nucleus (AGN), that houses a supermassive black hole at the centre of a galaxy. Gas falling into a supermassive black hole makes the quasar bright enough to outshine all stars in the galaxy.<\/p>\n The quasar explored by Webb is called SDSS J165202.64+172852.3, and has existed for around 11.5 billion years. Unusually, it takes on a red colour because the galaxy\u2019s light has been redshifted by its vast distance. The Webb Telescope was perfectly suited to examining the galaxy in detail because of its unparalleled sensitivity in infrared wavelengths.<\/p>\n This quasar is one of the most powerful known galactic nuclei that has been examined at such an extreme distance. Astronomers had speculated that its extreme emission could cause a galactic wind, pushing free gas out of its host galaxy, and possibly greatly influencing future star formation there.<\/p>\n To investigate the movement of gas, dust, and stellar material in the galaxy, the team used the telescope\u2019s Near Infrared Spectrograph (NIRSpec). This powerful instrument uses a technique known as spectroscopy to examine the movement of various outflows and winds surrounding the red quasar. NIRSpec can simultaneously gather spectra across the telescope\u2019s whole field of view instead of one point at a time, enabling Webb to simultaneously examine the quasar, its galaxy, and the wider surroundings.<\/p>\n Previous studies by NASA\u2019s Hubble Space Telescope, along with other observatories, called attention to the red quasar\u2019s powerful outflows. Astronomers had suspected that its host galaxy could be merging with an unseen partner; however, the team discovered that NIRSpec data was indicating three galaxies, not just one. Due to spectra over a broad area, the motions of all the surrounding material could be mapped, resulting in the conclusion that the red quasar was part of a dense knot of galaxy formation.<\/p>\nExamining the quasar in detail<\/h3>\n
