Explanation: Do you see the ring? If you look very closely at the center of the featured galaxy NGC 6505, a ring becomes evident. It is the gravity of NGC 6505, the nearby (z = 0.042) elliptical galaxy that you can easily see, that is magnifying and distorting the image of a distant galaxy into a complete circle. To create a complete Einstein ring there must be perfect alignment of the nearby galaxy's center and part of the background galaxy. Analysis of this ring and the multiple images of the background galaxy help to determine the mass and fraction of dark matter in NGC 6505's center, as well as uncover previously unseen details in the distorted galaxy. The featured image was captured by ESA's Earth-orbiting Euclid telescope in 2023 and released earlier this month.

Albert was apparently truly a genius.

to paraphrase a line from a good film back in the day:

genius is as genius does.

no one did more or better science than Albert.

This ring was only recently discovered in a well known galaxy near by. The European new telescope Euclid is what found the Ring.
