Gazing deeply at the vast landscape. It’s a mosaic of multiple images captured by the James Webb Space Telescope in near-infrared light, and it’s actually pulsating. Right of center is a cluster of bright white spiral galaxies that appear to be twisting into one another. Running throughout the scene is a light pink spiral that looks like a pinwheel spinning in the wind. Bright foreground stars are set once morest blue, announcing their presence with Webb’s prominent octagonal diffraction peaks. Don’t miss the unconventional sight: in the bottom row, the second square from the right. At its right edge, a misshapen blue galaxy is surrounded by shiny clusters of blue and pink stars.

The black hole, located in the galaxy CEERS 1019, is more than 13 billion years old. CEERS 1019 is an extremely old galaxy that probably formed 570 million years following the Big Bang. “The black hole has a mass of approximately 9 million solar masses,” according to a NASA press release. The mass of the sun is a unit of mass equivalent to the sun in our solar system, which is regarding 333,000 times the mass of the earth. According to NASA, the black hole is “significantly less massive than other black holes that also existed in the early universe and have been detected by other telescopes.” “These behemoths are often more than a billion times the mass of the sun, and they’re easier to spot because they’re brighter.” Being able to bring such faint, distant black holes into focus is a key feature of the Webb telescope, which uses highly sensitive instruments to detect otherwise invisible light. “Observing this distant object with this telescope is like observing a black hole in our nearby galaxy,” Rebecca Larson, who received her doctorate this year from the University of Texas at Austin, said in a statement. data.” Larson, who led the discovery, is now a postdoctoral researcher in RIT’s School of Physics and Astronomy. Not only did the researchers pinpoint this fascinating black hole, they also discovered two other nearby black holes that appear to have formed regarding a billion years following the Big Bang and are also very light compared to other black holes from that time period. The Webb Early Evolution of the Universe Science (CEERS) expedition, led by UT Austin, also documented 11 new galaxies. This image of the CEERS 1019 galaxy shows the detection of the most distant active supermassive black hole in the universe known so far. They were identified by a series of telescopes in space and on the ground. Three of them were recently discovered by the James Webb Space Telescope’s Cosmic Evolution Early Release Science (CEERS) survey. (NASA, ESA, CSA, Leah Hustak/STScI) The relative size of CEER 1019’s central black hole has been a mystery to scientists. It’s not clear how such a small black hole formed in the early universe, which is known to create larger gravity wells. The CEERS 1019 galaxy has other interesting properties. For example, it looks like a string of three bright spots, rather than the single disk-like structure of many other galaxies. “We are not used to seeing so many structures in images at such a distance,” Jeyhan Kartaltepe, a member of the CEERS team at the Rochester Institute of Technology in New York, said in a statement. is partly responsible for driving the activity of this galaxy’s black hole, which may also lead to increased star formation.” According to NASA, the newly discovered galaxy is still “spitting out” new stars. These and other CEERS discoveries might lead to fascinating breakthroughs. “Webb was the first to discover some of these galaxies,” Seiji Fujimoto, a NASA Hubble researcher at the University of Texas at Austin, said in a statement. “This galaxy, along with other distant galaxies that we may discover in the future, may change our lives.” understanding of star formation and galaxy evolution throughout cosmic history.” The researchers also note that the black hole inside CEERS 1019 may only be the most distant active supermassive black hole on record for only a short time. The astronomy community is already providing a wealth of data to pinpoint other, more distant black holes. According to NASA, this mission can be accomplished in just “a few weeks”.
