James Webb Image Shows A Stunning Einstein Ring 12 Billion Light-Years From Earth

NASA released the first full-color images of distant universe by James Webb Space Telescope in July this year.

After that, this state-of-the-art space telescope has captured evidence of a supernova, carbon dioxide in the atmosphere of an exoplanet, and going a step further, James Webb has captured an image of a beautiful Einstein Ring.

This image was created using data captured by James Webb's MIRI detector. 

It was also observed using the telescope's NIRCam detector. The image was colored by Redditor u/Spaceguy44, who previously colored another James Webb image. The image of an Einstein ring is remarkable because such events are rare.

An Einstein ring essentially occurs when light from one galaxy or star passes through another galaxy or a massive object on its way to Earth.

Because the gravitational force of the larger object bends the light, it creates gravitational lensing. This creates a ring-life effect, whereby the galaxy's light appears as a nearly perfect ring.  

In this new image, the James Webb Telescope captures the galaxy SPT-S J041839-4751.8. The light from SPT-S J041839-4751.8 appears like an Einstein ring due to a foreground galaxy that has refracted light from it.

So, this new James Webb image of the Einstein Ring is not actually the galaxy that is producing the light. Instead, we see light from that galaxy only bending around the foreground galaxy.

Nevertheless, this image is quite breathtaking. Spaceguy44 created the image using data downloaded from the Space Telescope Science Institute's archives.

The Einstein ring that James Webb captured is located at a distance of about 12 billion light years from Earth. To colorize the image, Spaceguy44 says they used a set of filters, which they also published in their original Reddit post
