Dust in the System – How Saharan Storms Threate the Future of Solar Power in Europe
Credit: Unsplash/CC0 Public Domain As Europe increases its dependence on solar energy to achieve climate and energy security goals, it complicates the path forward for growing atmospheric phenomena: Saharan dust. A new study published at the European Union of Geosciences (EGU25) shows that mineral dust, which runs from North Africa to wind, is not only reducing solar (PV) generation across…

New analysis of asteroid dust reveals evidence of salt water in the early solar system.
In October 2020, a bans -size robot spacecraft temporarily touched the surface of Benne, a 525 -meter planet, 32 million kilometers from the earth. As part of NASA’s OSIRIS-REX mission, spacecraft not only spent two years of imaging as an planet, but also collected valuable samples of dust and small rocks from the poor surface of Bennu. In September 2023,…

Ocean dust identifies oldest ice near South America dating back 1.5 million years
Benthic foraminiferal oxygen isotopes and marine and ice dust records from ODP site 1090, IODP site U1537, Dome Fuji (DF), and Epica Dome C (EDC). Dating back up to 2 million years. Climate cycles are indicated by dominant patterns of 40,000-year, 100,000-year, and irregular mid-Pleistocene transitions (MPTs). Credit: Past Climate (2024). DOI: 10.5194/cp-20-1437-2024 Earth’s climate has experienced significant changes over…
