The total solar eclipse on August 12 produced some of the most spectacular images of this phenomenon in recent years. But the mini golden age of eclipses in Europe is just beginning. The so-called “Iberian eclipse trio” still has two events to go—and both promise to be even more incredible than the one that just
One of the most enduring mysteries that has been puzzling scientists forever is how the Sun’s outer atmosphere – the corona – is millions of degrees hotter than its surface. And how does the corona continue to remain so hot despite frequent eruptions during which it loses huge amounts of energy? Astrophysicists in India now
Regions such as Galicia, Asturias, Castile and León, Madrid, Aragon, Catalonia, the Valencian Community, and the Balearic Islands experienced the path of totality, while the rest of the country saw a partial eclipse. The solar corona glows as the moon completely blocks the sun during the totality phase, as seen from San Asensio in the
Explanation: Have you contemplated your home star recently? Featured here, a Sun partially eclipsed on the top left by the Moon is also seen eclipsed by earthlings contemplating the eclipse below. This spectacular menagerie of silhouettes was taken in 2012 from the Glen Canyon National Recreation Area near Page, Arizona, USA, where park rangers and
Observations and data reduction In this work we present observations acquired on 14 April 2025 between 21:38 ut and 21:41 ut using the world’s largest telescope for optical and infrared observations of the Sun, DKIST21. During the data acquisition, the atmospheric conditions were variable, with Fried parameter values during the best periods measured around \(Check back often
Explanation: What does the new sharpest image of our Sun show? Instability. To be clear, a certain kind of interactive process called the Kelvin-Helmholtz instability (KHI). This instability can create waves and swirls when two streams flow past each other — in this case variable streams of solar magnetic plasma. Long hypothesized to occur on the Sun’s surface, KHI streaks and swirls
