NASA’s James Webb Space Telescope (JWST) has captured a near perfect ‘Einstein Ring,’ a bull’s-eye pattern that forms when light from a galaxy or star passes through another galaxy or massive object, 12 billion light-years from Earth – one light year is about six trillion miles.
First predicted by Albert Einstein in 1915, the glowing circle forms because light from a distant galaxy, labeled SPT-S J041839-4751.8, is bending around another closer to Earth.
Astronomers have discovered hundreds of Einstein Rings, but in order for the JWST to capture the illuminous ring around a shining bright blue light it had to be perfectly aligned with the galaxy.
Thomas Collett, of the Institute of cosmology and gravitation at the University of Portsmouth, who discovered another Einstein Ring in 2018, explained that the two galaxies also have align along the telescope’s line of sight in order to create a ‘phenomenon, called strong gravitational lensing, where we see multiple images of the background galaxy.’

In 1915, German-born Einstein claimed that gravity is the result of massive objects warping the very fabric of the universe, what he called spacetime.
Experts have since been able to test his theory of General Relativity within the solar system and prove his groundbreaking work holds up to scrutiny, which has been found among hundreds of Einstein Rings.
The physicist’s theory of General Relativity states that massive objects cause a distortion in space time. And in the case of the Einstein Ring, light from a distant galaxy is being warped around another – thus causing a distortion.
The image, although snapped by JWST, was shared by Redditor Spaceguy44 who has been sifting through the raw data and colorizing images to share with the world.

The glowing formation was snapped by the telescope’s NIRCam (Near InfraRed Camera), which is designed to capture light from the earliest stars and galaxies.
This is how NASA hopes to learn more about the early universe and Big Bang.
Spaceguy44 explains that the distant galaxy has been warped into a perfect ring by a massive foreground galaxy.

‘This happens when the background galaxy, the foreground galaxy, and the observer perfectly line up. This means J0418 is actually directly behind the foreground galaxy, the Redditor shared.
‘We wouldn’t be able to see J0418 if it weren’t for the light-bending properties of gravity. Without the lensing effect, the galaxy would probably look like most distant galaxies: a small blob of light.’
Last August another Einstein Ring was spotted 3.4 billion light-years from Earth.
The image shows six luminous spots of light clustered at the center, four of which are forming a circle around a central pair.
The formation, however, only consists of two galaxies and a single distant quasar that is magnified as it passes through the gravitational field of the galaxies.
The quasar, known as 2M1310-1714, sits farther away from Earth than the pair of galaxies.

A quasar is the extremely bright nucleus of an active galaxy and its powerful glow is created by the incredible amounts of energy released by gas falling toward the supermassive black hole at its center
The light from the quasar has been bent around the galaxy pair because of their enormous mass, giving the incredible appearance that the galaxy pair are surrounded by four quasars — whereas in reality, a single quasar lies far beyond them,’ the European Space Agency (ESA) shared in a statement.
EINSTEIN’S GENERAL THEORY OF RELATIVITY
Albert Einstein (pictured) published his General Theory of Relativity in 1915
In 1905, Albert Einstein determined that the laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum was independent of the motion of all observers – known as the theory of special relativity.
This groundbreaking work introduced a new framework for all of physics, and proposed new concepts of space and time.
He then spent 10 years trying to include acceleration in the theory, finally publishing his theory of general relativity in 1915.
This determined that massive objects cause a distortion in space-time, which is felt as gravity.
At its simplest, it can be thought of as a giant rubber sheet with a bowling ball in the centre.

As the ball warps the sheet, a planet bends the fabric of space-time, creating the force that we feel as gravity.
Any object that comes near to the body falls towards it because of the effect.
Einstein predicted that if two massive bodies came together it would create such a huge ripple in space time that it should be detectable on Earth.
It was most recently demonstrated in the hit film film Interstellar.
In a segment that saw the crew visit a planet which fell within the gravitational grasp of a huge black hole, the event caused time to slow down massively.
Crew members on the planet barely aged while those on the ship were decades older on their return.
