What they observed is actually an Einstein ring, or a ring of light that has been warped by the gravitational pull of a massive object between the quasar and Earth — a process called gravitational lensing. The ring effect was first mentioned in the academic literature by Orest Khvolson in a short article in 1924, in which he mentioned the “halo effect” of gravitation when the source, lens, and observer are in near-perfect alignment. While practicing socially distant science, a group of researchers dug through old data from Keck Observatory on Mauna Kea in Hawaii and NASA's Chandra X-ray Observatory managed to spot a remarkable quasar, or an active galaxy emitting incredible amounts of light. The NASA/ESA Hubble Space Telescope has revealed a never-before-seen optical alignment in space: a pair of glowing rings, one nestled inside the other like a bull's-eye pattern.

Sometimes, when a distant celestial object is precisely aligned with another object, we see light bent into an “Einstein ring” or arc. Please refresh the page and try again. "The Berlin Wall was still up when this Einstein ring was first discovered, and all the data presented in our paper are from the last millennium," Stern said in a statement.

Astronomers Revisit First 'Einstein Ring' In Archival Data Submitted by chandra on Tue, 2020-06-09 09:07 This article appeared on NASA.gov , written by NASA public information officer Elizabeth Landeau, based on a press release from Keck Observatory . But with this new study, the team was able to determine the object's distance, and they found that it's 10 billion light-years away from Earth (or a redshift of z=1.849). Social distance science made possible with public W. M. Keck Observatory and NASA archive data.. Astronomers have combined two powerful astronomical assets, the Sloan Digital Sky Survey (SDSS) and NASA's Hubble Space Telescope, to identify 19 new "gravitationally lensed" galaxies. As time went by, this phenomenon—known as gravitational lensing—has become a powerful research tool in astrophysics. The ring is optically faint (R = 23.3), rising steeply into the near- and mid-infrared (K = 17.8; W2 = 13.4). Pictured above on the left, the gravity of a normal white galaxy has gravitationally distorted the light from a much more distant blue galaxy. 1997). A gravitational lens mirage. "As we dug deeper, we were surprised that such a famous and bright source never had a distance measured for it," Stern added. Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. This celestial object, which is an active galaxy emitting brilliant amounts of energy due to a black hole devouring material, is an exciting object in itself. The double-ring pattern is caused by the complex bending of light from two distant galaxies strung directly behind a foreground massive galaxy, like three beads on a string. It is one of eight similar objects found by combining two powerful astronomical assets, the Sloan Digital Sky Survey (SDSS) and NASA's Hubble Space Telescope. a radio image of mg 1131+0456, the first known einstein ring observed in 1987 using the very large array. We present spectroscopic and imaging observations of a candidate optical Einstein ring. Discovered in 1988, the system consists of a bright (S 74 MHz = 3.7 Jy) radio source imaged into a ring and two compact, flat-spectrum components separated by 2"1. This object was first observed in 1987 using the Very Large Array network of radio telescopes in New Mexico. Remarkably, though widely studied, the quasar’s distance, or redshift, remained a question mark. © Explanation: What's large and blue and can wrap itself around an entire galaxy?
