![]() ![]() It’s like planting a sapling, which takes less time to grow into a full-size tree than if you started with only a seed,” said Andy Goulding, research scholar in astrophysical sciences at Princeton University in New Jersey. “There are physical limits on how quickly black holes can grow once they’ve formed, but ones that are born more massive have a head start. The researchers want to know whether the giant celestial objects formed when massive clouds of gas collapsed or if they resulted from the explosions of the very first massive stars. Given the distance between Earth and the objects from the early days of the universe, when telescopes like Webb observe this light, it’s effectively like looking into the past. But data collected by the Webb telescope showed that UHZ1 is actually much farther away and located beyond the cluster at 13.2 billion light-years from Earth.Ī light-year, equivalent to 5.88 trillion miles, is how far a beam of light travels in a year. ![]() At first glance, the galaxy appeared in the same direction as a cluster of galaxies known as Abell 2744, which is located about 3.5 billion light-years from Earth. Gravity essentially warps and amplifies the light of distant galaxies in the background of whatever is doing the magnifying, enabling observations of otherwise invisible celestial features.Īstronomers detected the black hole in a galaxy called UHZ1. He was referring to an effect called gravitational lensing, which occurs when closer objects - in this case a galactic cluster - act like a magnifying glass for distant objects.
