Concerns Raised Over Impact of Satellite ‘Megaconstellations’ on Earth’s Magnetosphere
Ex-NASA physicist Dr. Sierra Solter-Hunt raises concerns about the impact of satellite ‘megaconstellations’ like Elon Musk’s Starlink on Earth’s magnetosphere. With SpaceX introducing wireless internet satellite debris into Earth’s atmosphere at an alarming rate, the accumulation of metal dust could distort or trap Earth’s magnetic field. Dr. Solter-Hunt warns of potential consequences like ‘atmospheric stripping’ and emphasizes the need for further research on the long-term effects of satellite deployment.
Astronomers Make Groundbreaking Discovery Regarding Supermassive Black Hole at Center of Milky Way Galaxy
Astronomers from the Event Horizon Telescope (EHT) collaboration and the Center for Astrophysics | Harvard & Smithsonian have captured a new image of the supermassive black hole Sagittarius A* (Sgr A*) in polarized light, revealing strong and organized magnetic fields spiraling from the edge of the black hole. This groundbreaking discovery sheds light on the nature of supermassive black holes and their magnetic fields, hinting at potential similarities and differences between these enigmatic cosmic entities.
Unusual Fluctuations in Jupiter’s Magnetic Field
Unusual fluctuations in Jupiter’s magnetic field could reveal secrets about the gas giant’s core. Scientists from Harvard University observed changes in the magnetic field, indicating the presence of mysterious waves deep inside Jupiter. These fluctuations, concentrated in the ‘Great Blue Spot’, suggest the presence of waves in the metallic core, potentially unlocking the forces governing Jupiter’s magnetic field.
Mysterious New Form of Magnetism Confirmed
Discover the confirmation of a new form of magnetism, altermagnetism, that sits between ferromagnetism and antiferromagnetism. This fundamental discovery could have significant implications for future electronics and is based on the characteristic of quantum objects called spin.
Colossal Magnetic Field Detected in Nuclear Matter
Researchers have observed the interaction between a state of matter known as a quark–gluon plasma (QGP) and a magnetic field 1000 times the strength of those on neutron stars. This observation is a step toward a better understanding of the strong nuclear force and puts limits on the possible value of the QGP’s electrical conductivity, informing models of the early Universe.
Researchers Simulate Iron Snow to Shed Light on Planetary Magnetic Fields
Scientists have long believed in the occurrence of a phenomenon known as iron snow in the molten iron cores of certain planetary bodies. Similar to the formation of snow crystals in the upper atmosphere, iron snow is thought to occur…
