Webb observes menagerie of lensed galaxies behind ‘El Gordo’ cluster – Astronomy Now

Peering at a galaxy cluster referred to as “El Gordo,” the James Webb House Telescope has noticed a bunch of background galaxies, magnified, warped and distorted by gravitational lensing to provide a menagerie of never-before-seen star swarms. El Gordo contains lots of of galaxies that existed when the universe was 6.2 billion years outdated. Essentially the most putting characteristic, maybe, is a brilliant arc of pink at higher proper nicknamed El Anzuelo, or The Fishhook, a lensed galaxy courting again 10.6 billion years (labeled B within the second picture under). Observers have been in a position to appropriate the distortions to seek out the background galaxy is disk formed however solely about 26,000 gentle years in diameter. They have been additionally in a position to decide star formation was slowing down in a course of referred to as quenching. One other intriguing characteristic is an extended skinny line at left of middle referred to as La Flaca, or The Skinny One (labeled A within the second picture under). It’s one other lensed galaxy some 11 billion gentle years away. Quite a few different gravitationally magnified galaxies are additionally seen. Click on on the picture under for a zoomed-in model.
