At Sci News: Transits through Milky Way’s Spiral Arms Helped Form Early Earth’s Continental Crust, Study Says

New research led by Curtin University geologists suggests that regions of space with dense interstellar clouds may send more high-energy comets crashing to the surface of the Earth, seeding enhanced production of continental crust. The findings challenge the existing theory that Earth’s continental crust was solely formed by processes inside our planet. Earth is unique Read More…

At Live Science: Solar storm from hole in the sun will hit Earth on Wednesday (Aug. 3)

Ben Turner writes: Thankfully, the storm is classified as weak. High-speed solar winds from a “hole” in the sun’s atmosphere are set to hit Earth’s magnetic field on Wednesday (Aug 3.), triggering a minor G-1 geomagnetic storm. Forecasters at the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center (SWPC) made the prediction after observing Read More…
