NASA’s James Webb telescope captures extreme views of merging galaxies.

Now that we have a powerful lens towards the deepest regions of the universe, the definition of “surprise” has changed slightly when it comes to astronomical photography. It’s no longer surprising that NASA’s James Webb Space Telescope is unveiling another splendid and ancient piece of space. At this point, we know we can’t expect more than that from a pioneering machine. Instead, each time the telescope sends back jaw-dropping cosmic images, you get more of a “JWST strikes again” feeling. And still, our jaws fall legally every time. A dissonant version of this kind of “surprise” has happened again. It’s pretty extreme. Last week, scientists gave JWST a stunning view of a merging galaxy cluster around a massive black hole with a rare quasar. I know a lot is going on here. But the team behind the discovery thinks it could be extended further. “We think something dramatic is going to happen in this system,” said Andrey Vayner, a Johns Hopkins astronomer and co-author of the study on the scene, which will be published soon in the Astrophysical Journal Letters, said in a statement. said. For now, a detailed overview of the findings can be found in papers published on arXiv. NASA, ESA and J. Olmsted (STScI) What’s particularly fascinating about this portrait is that the nearby quasars are considered “extremely red” quasars. near the beginning of time. In essence, all the cosmic light streams reaching our eyes and machines look like a long time ago because light takes time to travel through space. Moonlight takes about 1.3 seconds to reach Earth, so if you look up at the moon, you will see the moon 1.3 seconds ago. More specifically, for these quasars, scientists think it took about 11.5 billion years for light from the object to reach Earth. According to the team, this also makes this galaxy one of the most powerful of its kind ever observed at such an enormous distance (11.5 billion light-years away).” will be seen.” Vayner spoke of the area where the quasars anchored. Galactic rarity analysis We see several things in the colorful images provided by Vayner and his colleagues. Each color in this image represents a material moving at a different speed. ESA/Webb, NASA and CSA, D. Wylezalek, A. Vayner and Q3D team, N. Zakamska Left is a Hubble Space Telescope view of the area studied by the team, and in center is a magnified version. The point at which JWST caused zero. If you look at the far right of this image, you’ll see four individually color-coded boxes that allow you to analyze different aspects of the JWST data sorted by rate. For example, red moves away from us and blue moves toward us. This classification shows how each of the galaxies involved in the spectacular merger, including the extreme black hole and accompanying red quasar, behaves. “What you’re seeing here is just a small subset of what’s in the data set,” said Nadia L. Zakamska, a Johns Hopkins astrophysicist and co-author of the study, in a statement. I have highlighted the most surprising fact first. All the blobs here are baby galaxies merging into this mother galaxy, the colors are different speeds, and the whole thing is moving in a very complex way.” But already we’re seeing much more surprising information than the team initially expected: the Hubble and Gemini-North telescopes have previously shown galactic transition potential, but in a swarm that can be seen with JWST’s fancy infrared instruments. Hundreds of background galaxies of varying sizes and shapes appear with the Neptune system. ESA “In previous images, we thought we’d seen hints that galaxies were likely interacting with other galaxies during the merger process. Because it distorts the shape in the process,” said Zakamska. “But after I got the Webb data, I was like, ‘I have no idea what you’re looking at here. What is all this!’ I thought. We’ve been looking at these images for weeks.” It soon became clear that the JWST was showing at least three individual galaxies moving incredibly fast. They argued that this was one of the densest known galactic forming regions in the early universe. We believe we can display one artistic impression of the quasar P172+18 associated with a black hole 300 times more massive than the Sun ESO/M. Kornmesser Everything about this intricate image is captivating To us what Zakamska calls a “monster” There is a black hole, from which a very rare jet of light spews out, and in the course of a collision it looks like the Milky Way was from billions of years ago. So, dare I say? Cue, jaw drop.
