Prepare to be amazed! The Hubble Space Telescope has once again delivered breathtaking visuals, showcasing a distant galaxy located a staggering 19.5 billion light-years away from Earth. But here's the twist: we're seeing it as it was an incredible 11 billion years ago, when it was 'just' 5.5 billion light-years from us, journeying through the expanses of an ever-expanding universe.

Dubbed HerS 020941.1+001557, this awe-inspiring galaxy appears to us as a striking red arc, partially wrapping around a foreground elliptical galaxy named SDSS J020941.27+001558.4, which sits around 2.7 billion light-years from our planet. Right at the heart of this cosmic spectacle, the elliptical galaxy shines brightly, surrounded by a haze of stars emanating from its core.

But the intrigue doesn’t stop there! A third galaxy, SDSS J020941.23+001600.7, seems to intersect with the glowing red crescent of light from the distant galaxy. This enchanting alignment involves three galaxies and results in a gravitational lens effect known as an Einstein ring.

So, what exactly is an Einstein ring? It's a fascinating phenomenon that occurs when light from an incredibly distant object is bent around a massive object—like our foreground elliptical galaxy—situated between the observer and the lensed galaxy. When these celestial bodies align perfectly, they create the mesmerizing effect of an Einstein ring.

These rings can manifest as either complete or partial circles of light, depending on the alignment’s precision. While the effects might go unnoticed at a local scale, they become overwhelmingly clear when dealing with vast astronomical distances.

Not only do gravitational lenses bend and distort light, but they also magnify it. In this mind-blowing image, light from the distant galaxy dances through the warped spacetime shaped by the elliptical galaxy's gravitational pull, forming a captivating partial ring of light. It serves as a visual reminder of the wonders of our universe and the intricate dance of cosmic bodies.
