There are often surprises when looking up into the night sky. This time, a rare sighting—an Einstein ring—was captured by the James Webb Space Telescope (JWST). The glowing, eye-like circle in space is really a distorted image of two galaxies instead of one thing.
An Uncommon Cosmic Illusion
One fascinating visual trick in space is the Einstein ring. It occurs when the light from a galaxy behind a big object gets curved. Einstein's theory of relativity is specifically to blame for this effect, which is called gravitational lensing.
The elliptical galaxy within the Hydrus constellation is visible in the recently created public image. First galaxy's luminous center is encircled by a halo of pulled-out orange and blue light from a second galaxy hidden behind it.
The gravitational lensing process was explained by the European Space Agency (ESA). "This effect is too subtle to detect locally but becomes apparent on a gigantic scale," according to ESA officials. Such cosmic distortions allow astronomers to study galaxies that otherwise would be invisible.
Taking Pictures of an Amazing Scene
It was released to the public by the Canadian Space Agency and ESA on March 27. They made it their "picture of the month." It was captured by JWST's Near-InfraRed Camera with assistance from Hubble's Advanced Camera for Surveys and Wide Field Camera 3.

Scientists are able to study galaxies that would otherwise remain invisible due to such cosmic distortions.

This technique also aids in the study of black holes and dark matter. One may only reveal the existence of such objects by warping and enlarging background stars, since they themselves do not emit light. "These objects are ideal for studying galaxies too far away to observe otherwise," said the European Space Agency.
JWST's photo of the Einstein ring is a new vision of deep space. Each photograph broadens our understanding of the universe and its secrets.
