Scientists may add a new dwarf planet to the official roster of our solar system. The distant, icy body, provisionally dubbed 2026 ED138, orbits our system beyond Pluto. It was spotted earlier this month by a scientist combing through data from the Simonyi Survey Telescope at the NSF-DOE Vera C. Rubin Observatory.
In nonreciprocal active matter, agents act differently on each other, seemingly in violation of Newton’s third law. This principle can result in various active matter traits, such as self-propulsion, molecular regulation and collective motion.
The Stanislaus County Sheriffs Office operation was funded by a grant from the California Office of Traffic Safety, through the National Highway Traffic Safety Administration, supporting pedestrian safety enforcement and education
Astronomers using the European Southern Observatory’s Very Large Telescope (ESO’s VLT) have found a rare disk of debris around a dead star that provides a glimpse of what may happen to our solar system. Unlike in similar systems previously found, the debris—the leftovers of planets that once orbited the star—is organized in a double disk, the two parts separated by a clear gap. The disk appears to be shaped by two planetary bodies, one possibly as big as Pluto, that have survived the violent death of the star.
Long before modern astronomy, humans looked to the stars and were astounded by what they saw. Even by the most ancient reckoning, the night sky offered enough to inspire awe and wonder, make us feel insignificant, fire our imaginations and foster hope and a sense of connection. Yet, for as long as humans have surveyed the heavens, they have seen no indication that life as we know it exists elsewhere—what has come to be known as the “Great Silence.”
Envision a material whose magnetic properties and electronic topology can be toggled by exposure to light, paving the way for future electronic devices that do not rely on traditional electrical switching, which wastes energy by producing heat.
There is a problem in low Earth orbit, and it’s growing. According to the European Space Agency, there are about 19,440 satellites on orbit, 3,540 of which are nonfunctioning and/or not emitting a signal to warn other spacecraft of their location. The need to service these sleepwalking satellites in space will only increase as more are launched.
Neutrinos are among the most abundant particles in the universe, but they are also among the most elusive. Nearly massless, they are produced by nuclear reactions in the sun, exploding stars, particle accelerators and even the decay of radioactive elements on Earth. They interact so weakly with ordinary matter that trillions pass through each person every second without leaving a trace. Studying these ghostly particles could help answer some of the biggest questions in physics, from the nature of dark matter to why matter exists at all.
The European Space Agency’s Hera spacecraft for planetary defense has resolved its two target asteroids separately for the first time, revealing the binary nature of the Didymos system, currently some 197 million km (122 million miles) away from Earth.
Researchers from Jülich, Aachen and Cologne have performed a quantum operation on a qubit in just 6.8 nanoseconds—with more than 99.98% accuracy. Such operations typically take several tens of nanoseconds in superconducting quantum computers. The paper was published in Nature Communications.
Researchers at the Osaka Research Institute of Industrial Science and Technology (ORIST), in collaboration with the University of Osaka and Tohoku University, have developed a flexible and stretchable silicon material whose response to terahertz waves can be mechanically tuned. By etching microscopic spiral springs into silicon, the team made the fragile material bendable and stretchable.
Adelaide University quantum engineers have found a new way to improve some of the world’s most sensitive sensors of electromagnetic fields, a breakthrough that could help advance brain imaging, medical diagnostics, communications technology and next-generation quantum devices.
The man pointed a BB gun that appeared to be a firearm at Phoenix Police officers, prompting officers to fire shots; while on the ground, he raised the gun again
Over 1,645 Martian days, NASA’s Perseverance Mars rover measured the fine and ultrafine Martian dust particles found clinging to samples of spacesuit materials that are carried aboard the rover, including particles small enough to penetrate the lungs and enter the bloodstream. The findings are published in the Proceedings of the National Academy of Sciences and could inform spacesuit and habitat design, dust-removal procedures and crew health standards for future NASA missions to Mars.
Earth may have produced much of its water during the planet’s formation, as rocky pebbles reacted with the hydrogen-rich atmosphere surrounding the young planet, according to new research published in Nature Geoscience. The findings offer a potential explanation for how Earth acquired one of the essential ingredients for life and suggest that similar water-producing processes could be common on rocky planets beyond our solar system.
