Weird Anomaly by Edmund Chan

: What is creating the structure in Comet NEOWISE’s tails? Of the two tails evident, the blue ion tail on the left points directly away from the Sun and is pushed out by the flowing and charged solar wind. Structure in the ion tail comes from different rates of expelled blue-glowing ions from the comet’s nucleus, as well as the always complex and continually changing structure of our Sun’s wind. Most unusual for Comet C/2020 F3 (NEOWISE), though, is the wavy structure of its dust tail. This dust tail is pushed out by sunlight, but curves as heavier dust particles are better able to resist this light pressure and continue along a solar orbit. Comet NEOWISE’s impressive dust-tail striations are not fully understood, as yet, but likely related to rotating streams of sun-reflecting grit liberated by ice melting on its 5-kilometer wide nucleus. The featured 40-image conglomerate, digitally enhanced, was captured three days ago through the dark skies of the Gobi Desert in Inner Mongolia, China. Comet NEOWISE will make it closest pass to the Earth tomorrow as it moves out from the Sun. The comet, already fading but still visible to the unaided eye, should fade more rapidly as it recedes from the Earth. via NASA

USS Harry S. Truman Strike Group Flyover

The U.S. Navy Flight Demonstration Squadron, the Blue Angels, flew over Nimitz-class aircraft carrier, USS Harry S. Truman (CVN 75), on a return transit to Naval Air Station Pensacola following their annual flight over the U.S. Naval Academy commissioning ceremony May 20, 2020. The Harry S. Truman Carrier Strike Group (HSTCSG) remains at sea in the Atlantic as a certified carrier strike group force ready for tasking in order to protect the crew from the risks posed by COVID-19, following their successful deployment to the U.S. 5th and 6th Fleet areas of operation.
