Webb Telescope May Have Already Found Most Distant Known Galaxy

News 18  

Just a week after its first images were shown to the world, the James Webb Space Telescope may have found a galaxy that existed 13.5 billion years ago, a scientist who analyzed the data said Wednesday. GLASS-z13 was spotted in so-called “early release” data from the orbiting observatory’s main infrared imager, called NIRcam — but the discovery was not revealed in the first image set published by NASA last week. When translated from infrared into the visible spectrum, the galaxy appears as a blob of red with white in its center, as part of a wider image of the distant cosmos called a “deep field.” Naidu and colleagues — a team totaling 25 astronomers from across the world — have submitted their findings to a scientific journal. Naidu said another team of astronomers led by Marco Castellano that worked on the same data has achieved similar conclusions, “so that gives us confidence.” ‘Work to be done’ One of the great promises of Webb is its ability to find the earliest galaxies that formed after the Big Bang, 13.8 billion years ago. For instance, the galaxy is the mass of a billion Suns, which is “potentially very surprising, and that is something we don’t really understand” given how soon after the Big Bang it formed, Naidu said.
