ESA’s first Scout mission, HydroGNSS, was launched on 28 November 2025, marking a significant step in advancing global understanding of water availability and the effects of climate change on Earth’s
MSU researcher Katie Maloney contributed samples of rare, exceptionally well-preserved seaweed fossils (e.g., macroscopic algae) from Yukon Territory, Canada. These fossils are almost one-billion years old and represent one of
A red giant orbiting a dormant black hole is spinning impossibly fast and contains chemistry that makes it look ancient when it’s actually relatively young. By listening to faint vibrations
