Scientists used supercomputers to simulate the final moments of a neutron star being torn apart by a black hole, revealing crust fractures, magnetic shocks, and potential electromagnetic signals like radio bursts and gamma rays, which could help detect such cosmic events with telescopes.
Researchers have successfully created a strong coupling between magnons and phonons in a thin film at room temperature, using shear sound waves to link ultrasound and magnetic waves. This breakthrough could lead to the development of hybrid wave-based devices for information processing with minimal losses, potentially opening the door for exciting progress in information and communication technologies. The key element enabling this work was a nano-structured surface acoustic wave resonator, which enhanced shear sound waves and allowed for a strong coupling between surface sound waves and magnets in the resonator.
Mysterious high-frequency magnetic waves detected by the Solar Orbiter spacecraft may explain why the sun's upper atmosphere, known as the corona, is 200 times hotter than its surface. This phenomenon, known as the coronal heating problem, has puzzled scientists for decades. Observations of small and rapid oscillations in magnetic structures in the corona suggest that magnetic waves could be responsible for heating the corona. Further research and observations will be conducted to confirm this link and understand the role of high-frequency magnetic waves in coronal heating.
Scientists have long been puzzled by the fact that the solar corona, the atmosphere of the Sun, is about 200 times hotter than its surface. A new study proposes that high-frequency magnetic waves could be responsible for heating up the corona. Recent observations have shown that transverse oscillations in the smallest magnetic structures in the corona could play a key role in delivering the necessary energy. The research, conducted using data from the Solar Orbiter and other solar observatories, suggests that these fast oscillations contribute enough energy to explain the heating in the corona. Further investigations are underway to discover higher-frequency magnetic waves and solve this long-standing mystery.
Scientists using the Solar Orbiter spacecraft have discovered small-scale fast-moving magnetic waves on the sun's surface that may explain the inexplicably high temperatures of the corona, the sun's outer atmosphere. These waves produce significant energy and could account for the temperature difference between the sun's surface and the corona. The findings provide new evidence that magnetic waves play a key role in heating the corona, a mystery that has puzzled scientists for decades.
Beneath the Earth's surface lies a world of mysteries and strange phenomena, including a subterranean biosphere full of microorganisms, a second hidden core within the core, a potential diamond factory, never-before-seen magnetic waves, evidence of Earth's galactic travels, a core leaking helium from the Big Bang, a giant river under Antarctica, a hidden zone beneath tectonic plates, unidentified structures near the core, and a Goliath ocean of water that could fill every ocean on Earth three times over.
