A very rare astronomical phenomenon has made headlines lately for good reason. It will be hundreds of years before we can see Jupiter and Saturn this close together again. However, there are still some "really weird and very rare phenomena" that can be seen in our night sky right now. The only problem is that you need to have access to Hubble in order to observe this phenomenon.
As always, Hubble delivers absolutely breathtaking images. This shows a gravitational lens effect, which is an almost perfect example of an "Einstein ring". The image of this ring, named GAL-CLUS-022058s or, in an enlightened astronomical branding, the "melted ring," was released late last week.
Video about the details of the gravitational lens.
This branding idea came in part from the physical appearance of the object, which actually looks like a molten metal ring. But it also came from the location of the object itself. The image is in the southern constellation Fornax (the furnace) and shows an extremely distant galaxy, the light of which is bent by a much narrower galaxy cluster.
Another Einstein ring. This is called LRG 3-757. This image was discovered by the Sloan Digital Sky Survey, but this image was captured by Hubble's Wide Field Camera 3.

One of the advantages of this lens flare is that scientists can better examine the galaxy further away, which otherwise might have been completely invisible. While this is not the only known example of the appearance of phenomena, it is one of the most noticeable. But there is much more to be found that Hubble will continue to do, regardless of how the planets in our solar system align.
