James Webb Space Telescope has recently captured a detailed image of an unusual cosmic occurrence. The latest images released by European Space Agency shows a glowing ring in the depths of space. It also reveals an effect that is caused by a massive galaxy bending light from another galaxy hidden behind it. The phenomenon has been recorded in the constellation Hydrus. It has been observed that light from the background galaxy forms a ring due to gravitational bending.
According to the European Space Agency and the Canadian Space Agency the sight captured is known as an Einstein ring. It was reported that the effect is caused when a massive object bends light from another galaxy located behind it. The report further highlights that the foreground galaxy shown in the images belongs to a cluster known as SMACSJ0028.2-7537. The light from a distant spiral galaxy is being curved by the gravitational pull of the elliptical galaxy in front.
As per the official statement from ESA, the effect is a classic case of Albert Einstein's theory of general relativity. The agency highlighted that the large objects in space can warp space-time, which in turn, forces light to travel around them in curved paths. The report further mentioned that when the observer, the light source and the massive object align perfectly, the light appears as a full ring.
The image was shared as part of the March picture of the month initiative by the space agencies. The images were capture using the Near Infrared Camera instrument on the James Webb Space Telescope with the help of Hubble Space Telescope's Wide Field Camera 3 and Advanced Camera for Surveys.
It is also reported that such lensing phenomena assist astronomers in studying distant galaxies that would otherwise be too faint to observe. The ESA further noted that the magnification effect helps reveal the structure and composition of galaxies that existed shortly after the Big Bang.
