              1. Pic of Solar panels armor a hillside in China’s Anhui province, parting only for an access road. Distant ridges host wind turbines, another fast-growing component of an energy revolution that has helped ease air pollution and halt the growth of China’s carbon emissions.George Steinmetz 2. At the focus of the Shouhang Dunhuang plant’s mirrors, a tower set aglow by the concentrated sunshine holds molten salt at 565°C. The salt generates steam that powers a turbine—and because the molten material holds heat through the night, the plant can run nonstop. 3. The fiberglass halves of a single wind turbine blade take shape in a SANY factory in Shaoshan, China. Among the longest in the world, the finished blades extend 107 meters—the length of a soccer field. Demand is so high the factory runs 24/7. 4. A 90-meter needle threading through town, a turbine blade makes its way to a hilltop in Hunan province. China has installed nearly half of the world’s wind power capacity, and although wind is growing more slowly than solar, it generates more reliable power.

With Webb, researchers can study the properties and growth of dust grains within protoplanetary discs like this one, shedding light on the earliest stages of planet formation.

                            Digital cel-shaded art of a wibbly wobbly Dickinsonia, a weird wobbly lifeform from before the Cambrian era. It looks like a floppy frisbee with bilateral lines sectioning its body into many gelatinous ribs. It lives underwater surrounded by fleshy ‘plants’, including orange charnia with spots and neon green hylaecullulus. Since I’ve interpreted Dickinsonia as a transparent creature, the other life forms can be fuzzily seen through its body. This little scene is set on an isometric square chunk of sandy seafloor.

                              A paper today in Nature by Borlaff et al. on the impact of ever-increasing numbers of satellites in low-Earth orbit on space telescopes like Hubble, SPHEREx, & CHEOPS today, & Xuntian & ARRAKIHS in the future.

                              The number of proposed satellites is eye-watering, & the effects on astronomy horrendous – there are wider effects on pollution of the upper atmosphere & safety of key orbital assets as well.
