Research is actively underway to develop a “dream memory” that can reduce heat generation in smartphones and laptops while delivering faster performance and lower power consumption. Korean researchers propose a new possibility for controlling magnetism using the exchange interaction of electron orbitals—the motion of electrons orbiting around an atomic nucleus—rather than relying on the conventional […] As four astronauts travel around the moon on NASA’s Artemis II mission, they will venture beyond Earth’s protective magnetic field. The crew’s spacecraft, Orion, will carry and protect them as they journey into deep space and serves as the main protection against the sun’s intense power. During their 10-day flight, NASA and the National Oceanic […] A thick layer of haze around the ultra-low-density planet Kepler-51d likely obscures not only the strange planet’s composition, but also its origin, according to a new study. A team led by Penn State researchers used NASA’s James Webb Space Telescope (JWST) to take a deeper look at the “super-puff” planet that defies planetary formation models. […] All the essential ingredients to make the DNA and RNA underpinning life on Earth have been discovered in samples collected from the asteroid Ryugu, scientists said Monday. Go to Source Discovered in the Pictor II dwarf galaxy, star PicII-503 has an extreme deficiency in iron—less than 1/40,000th of the sun. This signature makes it the clearest example of a star within a primordial system that preserves the chemical enrichment of the universe’s first stars. PicII-503 also has an extreme overabundance of carbon, providing the missing […] The suspect ignored commands to get out of the vehicle and accelerated, dragging a tethered patrol vehicle that hit a Phoenix PD officer and an Arizona DPS trooper Go to Source The man first appeared to cooperate with a San Diego deputy before abruptly rolling up his window and reaching around the vehicle; he then grabbed a gun and fired a shot Go to Source Science in the modern era is increasingly reliant on enormous datasets and automated analysis. In astronomy, the Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST)—a ten-year survey covering the entire southern sky almost a thousand times over the next decade—will test the limits of this reliance. Go to Source […] Apollo 11 first landed astronauts on the moon in 1969, but the journey to the lunar surface actually began 43 years before, in snowy Massachusetts. Go to Source It’s well known that spaceflight causes muscle atrophy and other biological changes in reduced gravity, and especially in near-zero gravity (microgravity) environments. However, the gravity threshold needed to maintain sufficient muscle health in space is still unclear. Go to Source Gamma-ray bursts are the most violent explosions in the universe. In a fraction of a second, they can release more energy than the sun will emit across its entire 10-billion-year lifetime. Most are over before you’ve had time to register them, gone in seconds, minutes at most. So when something arrived on 2 July 2025 […] The case reached the state’s high court after a federal appeals ruling questioned whether officers had probable cause in the arrest of a man watering his neighbor’s flowers Go to Source It seems improbable that a satellite designed to monitor polar ice sheets and floating sea ice could accurately measure a disturbance in Earth’s magnetic field. But that is just what ESA’s CryoSat mission did earlier this year. This is a story of unique innovation in satellite technology. At the end of last year, the CryoSat […] Using data from the Magellan Clay telescope and the Canada-France-Hawaii Telescope (CFHT), astronomers have investigated a galactic globular cluster known as NGC 5824. Results of the new study, available in a paper published March 5 on the arXiv pre-print server, suggest that the cluster is embedded in a dark matter halo. Go to Source […] The Royal Astronomical Society (RAS) is alarmed by the threat to ground-based astronomy posed by proposals put forward by Elon Musk’s SpaceX and Reflect Orbital. SpaceX has applied to launch one million satellites to act as data centers to power artificial intelligence, but brightness estimates show that thousands would be visible to the naked eye, […] |
