The smallest magnetic loops ever seen in the sun's corona — imaged for the first time by the National Science Foundation's Daniel F. Inouye Solar Telescope — could be the bottom floor of the machinery ...

Astronomers using the Inouye Solar Telescope have captured the sharpest-ever images of a solar flare, revealing coronal loops as thin as 21 km wide. These threadlike plasma structures, imaged during ...

The figure shows loops with soap films spanning them. If the loops are sufficiently small they remain circular (a). As the length of the loop increases from (b) to (d) the initially circular shape ...
