Gamma-ray bursts are the most violent explosions in the universe. In a fraction of a second, they can release more energy than the sun will emit across its entire 10-billion-year lifetime. Most are over before you’ve had time to register them, gone in seconds, minutes at most. So when something arrived on 2 July 2025 […] The case reached the state’s high court after a federal appeals ruling questioned whether officers had probable cause in the arrest of a man watering his neighbor’s flowers Go to Source It seems improbable that a satellite designed to monitor polar ice sheets and floating sea ice could accurately measure a disturbance in Earth’s magnetic field. But that is just what ESA’s CryoSat mission did earlier this year. This is a story of unique innovation in satellite technology. At the end of last year, the CryoSat […] Using data from the Magellan Clay telescope and the Canada-France-Hawaii Telescope (CFHT), astronomers have investigated a galactic globular cluster known as NGC 5824. Results of the new study, available in a paper published March 5 on the arXiv pre-print server, suggest that the cluster is embedded in a dark matter halo. Go to Source […] The Royal Astronomical Society (RAS) is alarmed by the threat to ground-based astronomy posed by proposals put forward by Elon Musk’s SpaceX and Reflect Orbital. SpaceX has applied to launch one million satellites to act as data centers to power artificial intelligence, but brightness estimates show that thousands would be visible to the naked eye, […] Patches of the sun’s surface often show strong magnetic fields. These fields can emerge within a matter of hours, and can decay slowly or quickly, sometimes over days, weeks, or even months. Thanks to a new study about these long-lived active regions, we now know much more about the patches where these strong magnetic fields […] Heat shields are designed to protect the surface and cargo of a spacecraft as it enters an atmosphere. Aerospace engineers in The Grainger College of Engineering at the University of Illinois Urbana-Champaign recently observed a violently destructive difference in how heat shields function in atmospheres like Earth that contain oxygen versus nitrogen-rich atmospheres such as […] A study led by the University of Oxford has identified a new type of planet beyond our solar system—one that stores large amounts of sulfur deep within a permanent ocean of magma. The findings have been published in Nature Astronomy. Go to Source Electrons are tiny and constantly in motion. How they behave in a crystal lattice determines key material properties: electrical conductivity, magnetism, or novel quantum effects. Anyone aiming to develop the information technologies of tomorrow must understand what electrons do. At Forschungszentrum Jülich, a new tool is now available for this purpose: a momentum microscope that […] We’re starting to see just how exceptional our own solar system and its history is, as more exoplanets are discovered. A fourth exoplanet discovery in the LHS 1903 system made by ESA’s CHEOPS mission places a rocky world right where it shouldn’t be. This “inside-out system” could challenge our current understanding of planetary formation. Go […] Researchers from the Texas Center for Superconductivity (TcSUH) and the department of physics at the University of Houston have broken the temperature record for superconductivity at ambient pressure—a breakthrough that could eventually lead to more efficient ways to generate, transmit, and store energy. Go to Source Using the Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a new super-Earth exoplanet orbiting a star located about 83 light years away. The newfound alien world is slightly larger than Earth and encircles its host in less than four days. The finding was reported in a paper published Feb. 28 on the arXiv pre-print […] Neutrinos are extremely lightweight and electrically neutral particles that rarely interact with ordinary matter. Due to these rare interactions, neutrinos can travel across space almost entirely unaffected, carrying information about highly energetic cosmological events, such as exploding stars or supermassive black holes. Go to Source Following the deaths of Christian County Deputies Gabriel Ramirez and Michael Hislope, Probation Officer Patricia Drinkall is launching a petition-driven campaign to change bail and bond laws Go to Source Astronomers have employed the Australia Telescope Compact Array (ATCA) to investigate a peculiar pulsar wind nebula known as Vela X. Results of the new observations, published March 2 on the arXiv pre-print server, provide more hints about the properties and nature of this nebula. Go to Source |
