Inouye Telescope Captures 12-Mile Solar Vortices as Budget Request Slashes Funding 51%

Summary
August 5 images from the Daniel K. Inouye Solar Telescope revealed Kelvin-Helmholtz vortices on the sun’s surface for the first time, resolving features about 19 kilometers, or 12 miles, across.
That result depended on extreme heat control: a 12-kilowatt solar beam, more than seven miles of coolant piping, and a liquid-cooled heat-stop that dumps over 95% of incoming heat before it reaches instruments.
The observations could help explain how magnetic fields twist and store energy before flares and coronal mass ejections, improving understanding of space weather that can disrupt satellites, GPS, radio and power grids.
The breakthrough comes as the FY27 White House budget request would cut the telescope’s funding to $13 million from $26.4 million in FY25, with the observatory marked for operation at a reduced tempo.
Congress has not enacted the cuts, but the contrast highlights a broader risk for costly scientific infrastructure: such facilities are relatively easy to underfund and far harder to rebuild.
