Reading the Plasma Around M87*: The First Resolved, Dual-Frequency Map of the Giant's Shadow
A SHAO-led team used the Event Horizon Telescope and the GMVA to build the first spatially resolved, dual-frequency spectral map of M87*, tying the famous 2019 ring to the physical state of plasma near the event horizon at a ~30-microarcsecond transition.

The Sun Stirs Again: Sunspot AR4494 Fires an M3 Flare as Three Regions Crackle Into Late July
Sunspot AR4494 threw an M3.2 flare on July 26 while regions 4495 and 4496 added C-class pops. Earth's magnetic field stayed quiet, but forecasters put the odds at 45% for another M-flare and 10% for an X-flare over the next 24-48 hours.
