December 21, 2024 by Adithi Ramakrishnan Collected at: https://phys.org/news/2024-12-stars-orbiting-supermassive-black-hole.html Scientists have spotted what appear to be two stars whipping around each other near the supermassive black hole at the center of our Milky Way galaxy. Nearly every large galaxy has a supermassive black hole at its heart. The one in the middle of the Milky […]

December 21, 2024 by Francis Nimmo, The Conversation Collected at: https://phys.org/news/2024-12-moon-older-scientists-previously-thought.html A physicist, a chemist and a mathematician walk into a bar. It sounds like the start of a bad joke, but in my case, it was the start of an idea that could reshape how scientists think about the history of the moon. The […]

December 17, 2024 by Eric Stann, University of Missouri Collected at: https://phys.org/news/2024-12-tiny-particle-huge-potential-scientists.html Researchers recently made a groundbreaking discovery on the nanoscale: a new type of quasiparticle found in all magnetic materials, no matter their strength or temperature. These new properties shake up what researchers previously knew about magnetism, showing it’s not as static as once […]

December 20, 2024 by Royal Astronomical Society Collected at: https://phys.org/news/2024-12-dark-energy-doesnt-lumpy-universe.html One of the biggest mysteries in science—dark energy—doesn’t actually exist, according to researchers looking to solve the riddle of how the universe is expanding. Their analysis has been published in the journal Monthly Notices of the Royal Astronomical Society Letters. For the past 100 years, physicists have generally […]

December 20, 2024 by Mark Thompson Collected at: https://www.universetoday.com/170188/star-devouring-black-hole-spotted-by-astronomers/ A team of astronomers have detected a surprisingly fast and bright burst of energy from a galaxy 500 million light years away. The burst of radiation peaked in brightness just after 4 day and then faded quickly. The team identified the burst, which was using the […]

December 20, 2024 by Paul M. Sutter Collected at: https://www.universetoday.com/170119/can-entangled-particles-communicate-faster-than-light/ Entanglement is perhaps one of the most confusing aspects of quantum mechanics. On its surface, entanglement allows particles to communicate over vast distances instantly, apparently violating the speed of light. But while entangled particles are connected, they don’t necessarily share information between them. In quantum […]

December 19, 2024 by Brian Koberlein Collected at: https://www.universetoday.com/170174/a-binary-star-found-surprisingly-close-to-the-milky-ways-supermassive-black-hole/ Binary stars are common throughout the galaxy. Roughly half the stars in the Milky Way are part of a binary or multiple system, so we would expect to find them almost everywhere. However, one place we wouldn’t expect to find a binary is at the center […]

December 19, 2024 by Paul M. Sutter Collected at: https://www.universetoday.com/170120/what-makes-brown-dwarfs-so-weird/ Meet the brown dwarf: bigger than a planet, and smaller than a star. A category of its own, it’s one of the strangest objects in the universe. Brown dwarfs typically are defined to have masses anywhere from 12 times the mass of Jupiter right up […]

December 19, 2024 by Monash University Collected at: https://techxplore.com/news/2024-12-discovery-trimodal-energy-storage-material.html Monash University researchers have made a breakthrough in energy storage technology that could significantly advance the global shift away from fossil fuels. The discovery, detailed in a study published Dec. 18 in Nature, involves a new thermal energy storage (TES) material that could help harness renewable energy more effectively […]

December 18, 2024 by Birgit Krummheuer, Max Planck Society Collected at: https://phys.org/news/2024-12-moon-young-crust-violent-volcanism.html 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 […]
