Backyard astrophotographer captures Godzilla-scale solar plume at the sun’s edge (video)

Backyard astrophotographer Mark Johnston captured two timelapse views of solar prominences at the sun’s edge: a May 22, 2026 event showing plasma streams that appear to fall back as coronal rain, and a May 31, 2026 'Godzilla'-like plume looming above the solar surface. He explains the motion is driven by the Sun’s magnetic fields and gravity rather than flame. Filmed from Scottsdale, Arizona using a 160mm refractor with a hydrogen-alpha filter, the footage highlights giant plasma structures tethered by magnetic field lines and serves as a reminder to observe the Sun only with certified filters.

Scientists Uncover Explanation for Rain on the Sun

Researchers at the University of Hawai'i have discovered that the mysterious rain on the Sun, composed of superheated plasma, is influenced by shifting flows of elements like iron, silicon, and magnesium in the Sun's corona. This finding helps explain the rapid formation of coronal rain and suggests new insights into solar atmospheric dynamics and coronal heating. The study challenges previous models assuming constant elemental distribution and opens avenues for further research into solar phenomena.

Scientists Uncover the Mystery Behind 'Rain' on the Sun

Scientists have long struggled to explain the rapid formation of 'solar rain'—cool, dense plasma blobs that fall during solar flares. Recent research shows that allowing elemental abundances, especially low FIP elements like iron, to vary in models explains the quick cooling and condensation observed. This new understanding improves the accuracy of solar models, helping to better interpret solar activity and predict space weather effects.

Deepfake AI Unveils "Shooting Stars" and Solves Sun's Atmospheric Mystery

Solar astronomers using the European Space Agency's Solar Orbiter (SolO) have discovered "shooting stars" on the sun's corona. These meteor-like fireballs occur within the phenomenon known as coronal rain, where clumps of the sun's fiery material condense due to localized temperature drops. SolO's observations have provided the first high-resolution images of the coronal rain clumps and revealed that the falling gas can produce brief, intense brightenings and shock waves. This discovery offers important insights into the composition and thermodynamics of the sun's corona.
