How the Moon’s Hidden Protection Shields Against Solar Wind Erosion

Universe Today - Thu, 07/24/2025 - 7:29pm

It seems the Moon has been protecting itself from cosmic erosion all along! Using Apollo moon dust for the first time, a team of researchers found that the lunar surface's rough, porous texture acts as a natural shield against solar wind bombardment, thus reducing erosion rates by up to ten times more than previously thought. This groundbreaking finding not only solves a long standing puzzle about the Moon's thin atmosphere but also rewrites our understanding of how rocky planets lose material to space, with major implications for upcoming missions to the Moon and Mercury.

Apparently Vera Rubin Captured Images Of 3I/ATLAS Before It Was Even Discovered

Universe Today - Thu, 07/24/2025 - 7:29pm

Sometimes serendipity happens in science. Whether it’s an apple falling from a tree or a melting chocolate bar, some of the world’s greatest discoveries come from happy accidents, even if their stories may be apocryphal. According to a new paper on arXiv, there’s a new story to add to the archives of serendipitous scientific discoveries - Rubin happened to make observations of interstellar object 3I/ATLAS before its official discovery, while the telescope was still in its Science Validation survey, marking the earliest, high resolution images we will likely get of the comet at that time.
