Streak Patterns on Mars Likely Formed by Dust Rather Than Water Flow
Tuesday, 20 May 2025 10:18
New findings from Brown University and the University of Bern challenge the long-standing theory that certain streaks on Martian slopes are formed by flowing water. Using machine learning to analyze a comprehensive dataset of slope streak features, the research suggests these formations are more likely the result of dry processes, including wind and dust activity.
For decades, scientists h Laser ultrasound used to reveal the elasticity of space rock for the first time
Tuesday, 20 May 2025 10:18
Scientists and engineers at the University of Nottingham have measured the stiffness of space rock for the first time.
Many meteorites are made of crystalline materials, formed under exotic conditions that cannot be replicated on earth. The stiffness of the crystals that make up these materials has historically been difficult to measure and normally this requires scientists to grow a speci High Repetition Rate Ion Acceleration Achieved with Tabletop Lasers
Tuesday, 20 May 2025 10:18
Researchers at the Tata Institute of Fundamental Research (TIFR) in Hyderabad have achieved a significant breakthrough in laser-driven ion acceleration, demonstrating the potential for compact, high-repetition-rate proton acceleration using tabletop lasers. This advancement, detailed in a recent study in Physical Review Research, leverages small, millijoule-class lasers to produce megavolt energ Second CubeSat joins ESA’s Ramses mission to asteroid Apophis
