How can artificial intelligence (AI) be used to advance mapping and imaging methods on other planets? This is what a study presented at the 56th Lunar and Planetary Science Conference hopes to address as a lone researcher investigated using machine learning models to enhance mapping and imaging capabilities from orbital images obtained from the Mars Reconnaissance Orbiter (MRO) Context Camera (CTX), which is currently orbiting Mars.
Getting a probe to the icy giant planets takes some time—a journey to Uranus could take as long as 13 years, even with a gravity assist from Jupiter. However, several ideas are in the works to speed up that process, especially given the increased interest in sending a probe their way.
More than 60 years ago, the Search for Extraterrestrial Intelligence (SETI) officially began with Project Ozma at the Greenbank Observatory in West Bank, Virginia. Led by famed astronomer Frank Drake (who coined the Drake Equation), this survey used the observatory’s 25-meter (82-foot) dish to monitor Epsilon Eridani and Tau Ceti—two nearby sun-like stars—between April and July of 1960. Since then, multiple surveys have been conducted at different wavelengths to search for indications of technological activity (aka “technosignatures”) around other stars.
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 special single crystal, which in this case is not possible.
A research team from the School of Engineering at the Hong Kong University of Science and Technology has developed a new computational model to study the movement of granular materials such as soils, sands and powders. By integrating the dynamic interactions among particles, air and water phases, this state-of-the-art system can accurately predict landslides, improve irrigation and oil extraction systems, and enhance food and drug production processes.
At CERN’s Large Hadron Collider (LHC), lead atom nuclei, accelerated in opposite directions, collide at speeds close to the speed of light. In such scattering processes, the quarks and gluons that make up these nuclei collide, creating other quarks and gluons, produced by the fundamental interaction known as the “strong interaction.” The number of particles created is around one hundred times greater than the initial number.
Although glasses exhibit disordered atomic structures, X-ray and neutron scattering reveal a subtle periodicity. Researchers at the University of Tsukuba have demonstrated that this hidden periodicity—referred to as “invisible order”—plays a critical role in determining vibrational fluctuations in the terahertz (THz) frequency range, which significantly influence the physical properties of glass.
Whether diving off docks, cannonballing into lakes or leaping off the high board, there’s nothing quite like the joy of jumping into water.
A team of researchers from TU Dortmund University, the University of Paderborn, and the University of Nottingham has developed a new optical method to detect ultra-weak atomic motion. Their experiment performed in Dortmund has demonstrated unprecedented sensitivity of the detection of atomic motion in crystals by exploiting light interference.
