Using a new optical system, scientists at the U.S. National Science Foundation National Solar Observatory and the New Jersey Institute of Technology have captured the most detailed images of the complex movements in the sun’s atmosphere, the corona. The technology will allow scientists to better understand the extreme nature of the corona and produce computer models that more accurately predict space weather and potential Earth-impacting solar flares.
The researchers developed the new coronal adaptive optics system at the NSF-funded Goode Solar Telescope in California. Similar to a camera’s “autofocus” feature, the adaptive optics system continuously adjusts to counteract the blurring effect of the Earth’s atmosphere while isolating and zooming in on dynamic coronal features. The results of the study were published in Nature Astronomy.

In-brief analysis
May 28, 2025
The California Independent System Operator (CAISO), the grid operator for most of the state, is increasingly curtailing solar- and wind-powered electricity generation as it balances supply and demand amidst rapid renewables capacity growth.
Grid operators must balance supply and demand to maintain a stable electric system. The output of wind and solar generators is reduced either through price signals or, rarely, through an order to reduce output during periods of:
Congestion, when power lines don’t have enough capacity to deliver available energy Oversupply, when generation exceeds customer electricity demand
In 2024, CAISO curtailed 3.4 million megawatthours (MWh) of utility-scale wind and solar output, a 29% increase from the amount of electricity curtailed in 2023.
Solar accounted for 93% of all the energy curtailed in CAISO in 2024. CAISO curtailed the
