Earth’s Atmosphere Leaks to the Moon: A Surprising Lunar Mystery Solved
Introduction: A bold claim about our planet’s reach For decades, scientists have puzzled over a familiar lunar mystery: why does the Moon carry traces of our atmosphere in its outer layers? A burgeoning body of research now suggests that Earth’s atmosphere may be leaking into space far enough to settle on the Moon. If confirmed,…

Earth’s Atmosphere Leaks to the Moon: A Hidden Link Across Space
Overview: A surprising cosmic handshake For decades, scientists treated the Moon as a quiet, airless neighbor. Yet recent research upends that assumption by revealing a slow, continuous exchange between Earth’s atmosphere and the Moon’s surface. Over billions of years, atoms and molecules have traveled across space, joining the lunar exosphere and contributing to a faint,…

Theia and the Moon: Early Neighbors in the Solar System
Did Theia Start as a Nearby Planet? Rethinking the Moon’s Birth For decades, scientists have told a dramatic tale: a colossal asteroid-like body named Theia collided with young Earth, smashing and mixing to birth the Moon. This violent event, believed to have occurred about 4.5 billion years ago, has been the centerpiece of our understanding…

Production and Preservation of Lipid Biosignatures in SO4-Rich Hypersaline Lakes of the Cariboo Plateau
Introduction Hypersaline lakes and coastal brines on Earth offer valuable analogs for Martian environments, especially when their chemistries resemble sulfate- and magnesium-rich deposits observed in the solar system. A recent study investigates how lipid biomarkers, including fatty acids, alkanes, and ether-bound lipids, form and persist in Mg-SO4–rich hypersaline settings. By analyzing modern brines, salt deposits,…
