![]() The bars take shape when stars within spiral galaxies rotate in an orderly fashion, as they do in the Milky Way. Telescopes spot the oldest and most distant black hole formed after the big bang NASA/ESA/CSA/STScI/CXC/SAO/Ákos Bogdán/L. These images show the galaxy cluster Abell 2744 that UHZ1 is located behind, in X-rays from Chandra and infrared data from Webb, as well as close-ups of the black hole host galaxy UHZ1. This result may explain how some of the first supermassive black holes in the universe formed. X-ray emission is a telltale signature of a growing supermassive black hole. “This is surprising because galaxies were much more chaotic in the early universe and very few had similar structures to the Milky Way.”Ī study detailing the findings was published November 8 in the journal Nature.Įarly evolution of barred spiral galaxiesĪstronomers thought barred spiral galaxies such as the Milky Way didn’t appear until the universe reached at least half of its current age because it was believed that it took several billion years of galactic evolution before the massive collections of stars within galaxies could form central bars.Īstronomers found the most distant black hole ever detected in X-rays (in a galaxy dubbed UHZ1) using the Chandra and Webb space telescopes. “Finding ceers-2112 shows that galaxies in the early universe could be as ordered as the Milky Way,” said study coauthor Alexander de la Vega, a postdoctoral researcher at the University of California, Riverside, in a statement. The revelation, made possible by Webb’s highly sensitive light-detecting capabilities, is changing scientists’ understanding of galaxy formation and the beginning stages of the universe. While massive spiral galaxies are common in the Milky Way’s cosmic neighborhood, that hasn’t always been the case. He is a Spanish National Research Council postdoctoral researcher at Spain’s Centro de Astrobiología in Madrid.Īstronomers were surprised to see such a well-ordered and structured galaxy at a time when others were much more irregular. “Unexpectedly, this discovery reveals that galaxies that resemble our own existed already 11,700 million years ago, when the Universe had just 15% of its life,” said lead study author Luca Costantin in a statement. Given the distance between Earth and the objects from the early days of the universe, when telescopes like Webb observe light from the distant cosmos, it’s effectively like looking into the past. NASA/ESA/CSA/STScIĬosmic ‘Christmas tree’ dazzles in new image captured by Hubble and Webb The resulting wavelength coverage, from 0.4 to 5 microns, reveals a vivid landscape of galaxies that could be described as one of the most colorful views of the universe ever created. ![]() ![]() To make the image, in general the shortest wavelengths of light were color-coded blue, the longest wavelengths red, and intermediate wavelengths green. This panchromatic view of galaxy cluster MACS0416 was created by combining infrared observations from NASA's James Webb Space Telescope with visible-light data from NASA's Hubble Space Telescope. ![]()
