Amount of sunlight at Earth's surface shows long-term shifts tied to pollution
Sydney, Australia (SPX) Apr 10, 2025 While sunrise is constant, the intensity of sunlight that reaches Earth's surface is not. A new perspectives article by an international research team reveals that this solar variability occurs over decades, and is closely linked to air pollution trends and environmental policy. Published March 15 in Advances in Atmospheric Science, the study outlines the global phenomena of "dimming" and "brightening" and their specific impacts in China. "The amount of sunlight - which is solar radiative energy - ... read more |

Proba-3 Prepares for Solar Corona Observations with Stellar Alignment Test
Paris, France (SPX) Feb 26, 2025 The European Space Agency's Proba-3 mission is set to generate artificial solar eclipses in orbit, enabling scientists to conduct prolonged studies of the Sun's corona-observations that are otherwise limited to short durations during natural eclipses on Earth. In preparation for these investigations, researchers from the Royal Observatory of Belgium recently captured an image of a star field, marking the first use of the mission's coronagraph. Proba-3 carries ASPIICS (Association of Spacecraft for ... read more
