The Nördlinger Ries is a large circular impact crater in Bavaria and Baden-Württemberg, Germany, that formed a lake covering roughly 400 square kilometers before silting up over about two million years. Buildings in the town of Nördlingen were constructed from local stone containing an estimated 72,000 tonnes of microscopic diamonds, created when the impact struck a graphite deposit. The same event is also linked to moldavite tektites scattered as far as 450 kilometers away in the Czech Republic.
DJI unveiled its Osmo 360 II camera in Berlin, an upgrade over its predecessor with dual 1-inch square sensors capable of 8K60 recording, edging out Insta360's X6 which tops out at 8K50.

Because of an ongoing FCC restriction on new DJI hardware, the device is unlikely to launch officially in the United States.
