European scientists are taking advantage of this week’s solar eclipse to test a potentially groundbreaking instrument that could transform the way astronomers study the Sun. On that date, researchers will activate the Circular Slit Spectrometer (CISS), which the Turin-based team says will provide a unique new view of our life-giving star. Specifically, the device will focus on the corona, the outermost portions of the Solar atmosphere, and the hottest part of the Sun. The 2026 Solar Eclipse: A Trio of OccurrencesThis month, skywatchers will be treated to a trio of celestial events: a solar eclipse and the peak of the Perseids meteor shower on August 12, followed by a lunar eclipse between August 27 and 28. Closer to home, the Italian team believes CISS can separate the wavelengths of sunlight far more rapidly than existing instruments.
