- NASA: A cosmic warp occurs when the strong gravitational field of a massive object distorts it
A massive galaxy cluster in the constellation Cetus dominates the center of this image from the Hubble Space Telescope, according to the National Aeronautics and Space Administration. NASA “.
According to images published by “NASA”, it shows a quiet group of elliptical and spiral galaxies, but the galaxies surrounding the central cluster, called SPT-CL J0019-2026, appear to be extended into bright arcs, as if they were distorted by a giant magnifying glass. j
The cosmic twist
She said the cosmic warp, called gravitational lensing, occurs when the strong gravitational field of a massive object such as a galaxy cluster distorts and amplifies the light from background objects.
Usually, these objects are so far and dim that they cannot be noticed, but the magnifying power of the gravitational lens expands Hubble’s view deeper into the universe, NASA said.
This observation is part of an ongoing project to fill in the short gaps in the Hubble observational schedule by systematically exploring the most massive galaxy clusters in the distant universe, hoping to identify promising targets for further study with Hubble, NASA, the European Space Agency and the Canadian Space Agency James.
