Space Moss Survives 9 Months Outside the ISS: A Striking Astrobiology Breakthrough
Introduction: A Tiny Survivor in the Void In a remarkable demonstration of resilience, a moss species reportedly endured 9 months outside the International Space Station (ISS). Space is a hostile theater for life as we know it—vacuum, extreme cold, ultraviolet radiation, and scarce oxygen all converge to push organisms to their limits. Yet this moss,…

Space Radiation May Create Some Organic Molecules Detected on Icy Moons
Rethinking the Origins of Enceladus’s Organics For years, the plumes jetting from Saturn’s moon Enceladus have been a tantalizing clue in the search for habitability beyond Earth. The Cassini mission detected a suite of organic molecules in these icy geysers, suggesting a chemically rich environment beneath the frozen crust and a potential link to a…

Space Radiation May Create Some Organic Molecules Found in Enceladus Plumes
New insight into Enceladus’s chemistry Scientists are reconsidering how organic molecules detected in plumes erupting from Saturn’s icy moon Enceladus should be interpreted. A recent study proposes that some compounds previously thought to come from a subsurface ocean could instead be produced by natural radiation near the moon’s surface. While this doesn’t rule out a…

Space Radiation Could Create Organics on Enceladus and Other Icy Moons
Radiation Chemistry Isn’t Just for Earth: Implications for Enceladus For years, scientists have looked at the plumes erupting from Saturn’s icy moon Enceladus as a direct window into a hidden subsurface ocean. The idea was simple: material sampled in space could reveal the ocean’s chemistry, including potential building blocks of life. A growing body of…

Exclusive: NASA Astronaut Feels Incredible at 75. Here’s Why.
Exclusive: A Peek Into a 75-Year-Old Astronaut’s Perspective At the age of 75, Winston Elliott Scott stands as a testament to the enduring human spirit that drives space exploration. A veteran NASA astronaut who flew aboard two shuttles in 1996 and 1997, Scott logged just over 24 days in space and participated in three spacewalks.…
