NASA's James Webb Space Telescope has snapped a perfect shot of an "Einstein ring." The stunning halo is the result of light from a distant galaxy passing through warped space-time surrounding another galaxy aligned between the distant light source and Earth.
The new image, which was created by a Reddit-based astronomy enthusiast, is one of the best examples of the trippy astronomical phenomenon ever captured.

Archaeologists have unearthed one of Europe's largest Neolithic standing stone complexes near the city of Huelva in southwestern Spain, ahead of plans to grow avocados there.
The oldest upright stones — called "menhirs" in many parts of Europe, possibly from a Celtic word for "stone" — could be up to 7,500 years old, and the entire complex consists of thousands of individual stones spread out over 1,500 acres (600 hectares) of the sides and top of a small hill.
A melting ice patch in the mountains of Norway has revealed an archaeological surprise: a rare, three-bladed arrowhead used by Vikings more than a millennium ago.
The researchers unearthed the metal weapon while surveying a new site in the Jotunheimen Mountains, a millennium-old Viking hotspot for reindeer hunting located high above the treeline and punctuated by ice and stone. The team, which included archaeologists from the Museum of Cultural History in Oslo and Secrets of the Ice, an archaeological group based in Innlandet County, Norway, shared the findings a day later via an Aug. 25 Facebook post.
The remains of 17 people, mainly children, found in 2004 during a construction project in Norwich, England, are probably those of medieval Jews massacred for their religion, according to a new study.
Genetic analysis of the remains indicates the dead were all Ashkenazi Jews — that is, the descendants of Jews who had established communities in northern Europe, mainly in what are now Germany and France, during the early medieval period. (Many Ashkenzai later moved from these regions to eastern Europe, after the 11th to 13th centuries.) And other research suggests the dead people in Norwich were murdered during an antisemitic massacre in the city in 1190, by crusaders who had pledged to campaign against Muslims in Jerusalem.

New satellite images show the extent of the catastrophic floods now inundating Pakistan, leaving approximately one-third of the country underwater.
The worst of the floods occurred along a stretch of the Indus River that overflowed, forming a massive lake.
