Our feeds have been flooded with amazing photos of space since the first James Webb Space Telescope images were released.

This time, he captured an Einstein ring that was roughly 12 billion light years away. We cannot stop looking.

You can see the colorized image, which was shared by an astronomy graduate student, on the internet.

An Einstein ring is when a distant galaxy has been magnified and wrapped into an almost perfect ring by a massive galaxy in front of it.

12 billion light-years away is the location of the galaxy in question.

This is a more distant view that was processed by Spaceguy44.

If it wasn't for the Einstein ring, we wouldn't be able to see this universe.

The presence of Einstein rings allows us to look at the other side of the universe.

Einstein predicted the effect that this process would have.

The effect only happens when the distant, closer, and observer line up.

The stem and base of a wine glass creates a similar effect if you want to try it for yourself. It's possible to do it with a page of a book.

It is not uncommon to see Einstein rings. Hubble has previously taken pictures of Einstein rings.

This is not the first time that the Einstein ring has been captured.

Spaceguy44 colorized and released the region after it was captured by the NIR cam.

The image was not as clear as it could have been.

The data was downloaded from the MAST portal when the latest image was taken.

Three different filters are used to make the image. The red is the F 1000W filter. The F770W is green in the 7.7m wavelength. The F560W filters pick up 5.6m wavelength.

Astropy was used to align and colorize the images, followed by further processing in GIMP.
