Earth’s nearest neighboring body in the solar system is its moon, yet to date, humans have physically explored just 5% of its surface. It wasn’t until 2023—building on Apollo-era data and more detailed studies made in 2011–2012 by NASA’s automated GRAIL (Gravity Recovery and Interior Laboratory) mission—that researchers conclusively determined that the moon has a […] Neither gas nor liquid, supercritical fluids exhibit a unique mashup of the properties of both and arise when fluids are pushed to very high temperatures and pressures. Their properties make them ideal for a wide variety of chemical, pharmaceutical and environmental applications. Go to Source Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China, astronomers have discovered a new pulsar with a spin period of about two seconds. The newly detected pulsar, designated PSR J1922+37, was found in the direction of open cluster NGC 6791. The finding was reported in a paper published Dec. 11 on the arXiv preprint […] By peering into the cosmic dance of stars, a team led by researchers from the Leibniz Institute for Astrophysics Potsdam (AIP) has unraveled the complex structure of our Milky Way galaxy. Assuming that each observed star represents a larger population of stars sharing the same orbit, they have reconstructed the properties of these “hidden” stars, […] In-plane magnetic fields are responsible for inducing anomalous Hall effect in EuCd2Sb2 films, report researchers from the Institute of Science Tokyo. By studying how these fields change electronic structures, the team discovered a large in-plane anomalous Hall effect. Go to Source Figuring out certain aspects of a material’s electron structure can take a lot out of a computer—up to a million CPU hours, in fact. A team of Yale researchers, though, are using a type of artificial intelligence to make these calculations much faster and more accurately. Among other benefits, this makes it much easier to […] Our universe is a fascinating and mysterious place. Populated with planets, stars, meteors and other celestial bodies, it’s a never-ending source of wonder. Even with the technological revolution, we know very little about what’s going on in outer space. Are there some kinds of aliens or other life forms out there? What mysteries does […] Mechanical crystals, also known as phononic crystals, are materials that can control the propagation of vibrations or sound waves, just like photonic crystals control the flow of light. The introduction of defects in these crystals (i.e., intentional disruptions in their periodic structure) can give rise to mechanical modes within the band gap, enabling the confinement […] The magnetic moment of the muon is an important precision parameter for putting the Standard Model of particle physics to the test. After years of work, the research group led by Professor Hartmut Wittig of the PRISMA+ Cluster of Excellence at Johannes Gutenberg University Mainz (JGU) has calculated this quantity using the so-called lattice quantum […] Cleopatra, the Queen of Egypt, was one of the most renowned figures of her time. She was a beautiful, intelligent, and charismatic personality that used her power and influence to shape the course of history. However, her appearance and looks are still a mystery to the world as there are no clear images or […] Astronomers have discovered an important piece of the puzzle of how supermassive black holes were able to grow so quickly in the early universe: a special kind of active galactic nucleus so distant that its light has taken more than 12.9 billion years to reach us. This so-called blazar serves as a statistical marker: its […] Miniaturized spectroscopy systems that can detect trace concentrations at the parts-per-billion (ppb) level are of the utmost importance in applications ranging from environmental monitoring and industrial process control to biomedical diagnostics. However, the existing bench-top spectroscopy systems are too large, complex, and impractical for narrow-space use. Furthermore, the traditional laser spectroscopy techniques use bulky components […] After its formation, the moon may have been the scene of such immense volcanic activity that its entire crust melted several times and was completely churned through. At that time, the moon orbited significantly closer to Earth than today. The resulting tidal forces heated up its interior and thus powered the violent volcanism. Only Jupiter’s […] The moon has both a South and North Pole, but just how cold are they? For context, Antarctica’s coastal temperatures average around 14°F (-10°C), while the interior drops to -76°F (-60°C), making Earth’s South Pole one of the coldest places on the planet. Recent research shows that the South Pole of the moon experiences even […] At night, charged particles from the sun caught by Earth’s magnetosphere rain down into the atmosphere. The impacting particles rip electrons from atoms in the atmosphere, creating both beauty and chaos. These high-energy interactions cause the northern and southern lights, but they also scatter radio signals, wreaking havoc on ground-based and satellite communications. Go to […] |
