When solar storms strike Earth, they can disrupt power grids, rail systems, satellites, and even marine life. These effects arise because solar wind and geomagnetic activity disturb the magnetosphere–ionosphere system, generating electric and magnetic field variations that can resemble fainter signals from natural hazards. This risk is not theoretical. Go to Source […] Solar emissions exert ‘drag’ on space junk orbiting Earth. From historical measurements across a period of 36 years, researchers have now shown that space junk begins to fall down much faster once the sun’s activity across the solar cycle reaches approximately 67% of its peak. This result, which is expected to hold for station-keeping satellites […] The new focus on manned missions to the moon and Mars presents countless pressing challenges, including keeping humans alive in hostile environments. What happens when an astronaut or space tourist has a cardiac emergency millions of miles from the nearest hospital? Go to Source A half century after NASA’s Apollo 17 lunar module lifted off the moon’s northeastern near side quadrant, planetary scientists still don’t completely understand when or how our moon first formed. They do agree that it involved a major impactor—an object dubbed Theia by lunar scientists—that likely struck Earth some 4.51 billion years ago. But the […] A new model to predict how language changes over time has been developed by a statistical physicist at the University of Portsmouth. The model is a step towards understanding the “statistical physics of language,” a scientific theory which borrows ideas from the physics of interacting particles to explain how words, accents, and dialects spread, shift, […] Customs and Border Protection stated that Sean M. McDonough, 48, was participating in water training with the marine unit when he suffered a medical episode Go to Source A new paper from NASA’s Backyard Worlds: Planet 9 project announces that volunteers have essentially doubled the number of known brown dwarfs, with over 3,000 new discoveries made over the past 10 years since the project began. Brown dwarfs are balls of gas the size of Jupiter, less massive than stars. There’s one for every […] NASA’s Juno spacecraft captured this view of Thebe, the second largest of Jupiter’s inner moons, during a close pass on May 1, 2026. The spacecraft’s Stellar Reference Unit (SRU) captured this image from a distance of approximately 3,100 miles (5,000 kilometers) at a resolution of about 1.9 miles (3 kilometers) per pixel. Go to Source […] This series of images shows NASA’s Curiosity Mars rover as it got a rock stuck to the drill on the end of its robotic arm, and—after waving the arm and running the drill a few times—finally detached the rock. The imagery showing the entire process was captured by the black-and-white hazard cameras on the front […] A collaborative team of scientists has discovered that life on Earth over three billion years ago relied on the metal molybdenum, which was incredibly scarce in the environment at the time. The study, published in Nature Communications, is the first to show that molybdenum was used by ancient life this far back in our planet’s […] A two-dimensional lamellar crystal composed of atomically thin layers of lead iodide (PbI2) could be used to manufacture a new generation of circuits that use light and mechanical vibrations (rather than electrons) to transmit information in the terahertz frequency range. Go to Source Electronic nematicity is a phase of some crystalline solids in which electrons’ collective properties, such as charge or spin densities, organize themselves into ordered patterns, lowering the crystal’s rotational symmetry. This phase is found across a wide range of diverse materials, making nematicity crucial to understanding emergent solid-state phenomena, such as unconventional superconductivity and magnetism. […] More than 100 Oakland, San Francisco and CHP officers participated in the operation that trapped riders in between agencies on the bridge, leading to multiple arrests Go to Source An international team of astronomers has analyzed the data from the James Webb Space Telescope (JWST) and Atacama Large Millimeter/submillimeter Array (ALMA) to investigate giant molecular clouds in nearby galaxies. The new study, presented April 27 on the arXiv preprint server, unveils crucial information regarding the lifetime of more than 100,000 such clouds across 66 […] Across the Milky Way galaxy, a planetary odd couple is circling a star some 190 light years from Earth. A normally “lonely” hot Jupiter is sharing space with a mini-Neptune, in a rare and unlikely pairing that’s had astronomers puzzled since the system’s discovery in 2020. Go to Source |
