The universe is warped. And you can see it in a new cosmic photo captured by the James Webb Space Telescope, the most powerful space observatory ever built. Astronomers pointed the giant instrument, which orbits 1 million miles from Earth, at a cluster of galaxies around 6.3 billion light-years away. This cluster of galaxies, called SDSS J1226+2149, holds so much star and planetary weight that it's literally warping space, like a bowling ball sitting on a mattress. The warped cosmic area distorts and magnifies the massive objects in the distance. "This effect, referred to by astronomers as gravitational lensing, occurs when a massive celestial object such as a galaxy cluster causes a sufficient curvature of spacetime for light to be visibly bent around it, as if by a gargantuan lens," writes the European Space Agency. SEE ALSO: Webb telescope just found massive objects that shouldn't exist in deep spaceIndeed, there is a giant cosmic lens between us and the objects behind SDSS J1226+2149. This natural lens, combined with the viewing power of the Webb telescope, allows astronomers to glimpse some of the earliest galaxies ever formed, born over 13 billion years ago when the universe was still young. In the image below, in the lower right area, you can see poignant examples of distorted light caused by warped spacetime. These are the red, elongated shapes. In particular, there's a red, "long, bright, and distorted arc spreading out near the core," the space agency explains, an object dubbed "the Cosmic Seahorse." Such powerful magnification allows scientists to peer into this galaxy and grasp the star formation inside this distant realm of space. This Tweet is currently unavailable.

The Webb telescope, which hasn't yet operated for even a year, has years of unprecedented insights ahead. And it won't just be looking at profoundly distant galaxies. The Webb telescope's powerful abilitiesThe Webb telescope, a scientific collaboration between NASA, the ESA, and the Canadian Space Agency, is designed to peer into the deepest cosmos and reveal unprecedented insights about the early universe. But it's also peering at intriguing planets in our galaxy, and even the planets in our solar system. Related Stories

Update April 1, 2023:This story was updated to correct the distance of galaxy cluster SDSS J1226+2149. The cluster is 6.3 billion light-years away, not 6.3 billion miles. |
