Three solar prominences erupt in rare artificial-eclipse footage from ESA's Proba-3

ESA's Proba-3 mission captured a five-hour artificial eclipse, producing a time-lapse of three solar prominences erupting from the Sun's corona. By aligning the coronagraph with an occulter, scientists can study the sun’s faint outer atmosphere in unprecedented detail, combining Proba-3 data with NASA's Solar Dynamics Observatory imagery. The prominences appear to erupt without the bright flares typical of solar explosions and are cooler than the million-degree corona, offering clues to why the corona is so hot and how these plasma eruptions contribute to solar activity.

Proba-3’s Eye on the Sun Reveals Inner Corona and Eruptions

ESA’s Proba-3 uses two formation-flying spacecraft and the ASPIICS coronagraph to image the Sun’s inner corona, showing the hot, faint yellow halo and three helium-emission prominence eruptions observed during a five-hour window on Sept. 21, 2025. The animation combines ASPIICS data with NASA’s SDO/AIA imagery to illustrate how artificial eclipses let scientists study the corona’s dynamics, including prominences (cooler plasma) erupting into space and the corona’s light from scattered sunlight and helium emission.
