Researchers reveal that spacecraft observations can conceal the true movement of particles in near-Earth space, challenging traditional assumptions about radiation belt dynamics. The study highlights a fundamental challenge for space scientists: different physical processes can produce similar observational evidence.
A Boston University-led study found that the solar wind strips away Mars' atmosphere by generating Kelvin-Helmholtz waves, similar to wind on Earth. The process drives atmospheric ion escape, with plasma clouds facilitating bulk escape.
Researchers suggest that extreme space weather may have far worse effects on Earth's technology than previously thought. The study, published in Nature, found a direct relationship between solar wind strength and electric currents in the upper atmosphere, indicating no upper limit to Earth's response.
Researchers discovered the Zwan-Wolf effect in the Martian atmosphere, which helps move solar wind plasma around the planet and makes it less dense. This finding advances scientists' understanding of how the sun interacts with the solar system, particularly on unmagnetized bodies like Mars.
Scientists use XL-Calibur telescope to measure polarization of light around Cygnus X-1 black hole, gaining insights into matter's fall and energy release. The observations will be used to test computer simulations and shed light on black hole physics.
A world-first study has proven microbes essential for human health can survive the extreme forces of space launch. The spores of Bacilus subtilis bacteria were launched high into the sky and found to withstand rapid acceleration, microgravity, and rapid deceleration.
The project aims to improve propellant and life-support compound production in lunar and Martian environments. The researchers will evaluate the performance of a patent-pending electrolyzer developed with NASA support, testing its ability to produce fuel and oxygen.
Researchers mapped electron density in the ionosphere and observed unique 3D wave patterns after the 2024 Noto Peninsula Earthquake, showing earthquakes generate waves from multiple points along the entire fault line. The study provides new insights into how earthquakes affect the upper atmosphere.
Scientists have discovered birth sites of gigantic elliptical galaxies, suggesting large gas flows and galaxy collisions created these ancient systems. The research, published in Nature, may finally unravel the enigma of how these giant galaxies formed.
The University of Washington's STRIVE project aims to understand the troposphere and stratosphere, where the ozone layer resides, and their interface. This will help monitor changes in the ozone layer, air quality, and climate processes.
