Coronal loops, well-defined hot strands of plasma that arch out into the sun’s atmosphere, are iconic to the sun’s imagery. But many of the supposed coronal loops we see might not be there at all.

Many coronal loops — ropey strands of plasma that scientists have long thought existed in the Sun’s atmosphere — may actually be optical illusions, according to a new paper that challenges prevailing ...

BOULDER, Colo. — Massive arches of plasma in the sun’s atmosphere, called coronal loops, have long been used by scientists to measure the temperature and density of our star. These features have ...

The highest-resolution images of a solar flare captured at the H-alpha wavelength (656.28 nm) ever captured may reshape how we understand the sun's magnetic architecture—and improve space weather ...
