A large galaxy cluster within the constellation Cetus dominates the middle of this picture from the NASA/ESA Hubble Area Telescope. This picture is populated with a serene assortment of elliptical and spiral galaxies, however galaxies surrounding the central cluster—which is called SPT-CL J0019-2026—seem stretched into vivid arcs, as if distorted by a gargantuan magnifying glass.
This cosmic contortion, known as a gravitational lens, happens when the highly effective gravitational area of a large object like a galaxy cluster distorts and magnifies the sunshine from background objects. These objects would usually be too distant and faint to watch, however the magnifying energy of the gravitational lens extends Hubble’s view even deeper into the universe.
This statement is a part of an ongoing challenge to fill quick gaps in Hubble’s observing schedule by systematically exploring probably the most large galaxy clusters within the distant universe, within the hopes of figuring out promising targets for additional research with each Hubble and the NASA/ESA/CSA James Webb Area Telescope. This explicit galaxy cluster lies at an unlimited distance of 4.6 billion light-years from Earth.
