Earth's magnetic field intermittently shielded us during cosmic ray influx 41,000 years ago Berlin, Germany (SPX) Apr 22, 2024 Earth's geomagnetic field, while generally shielding the planet from cosmic and solar radiation, experiences periods of significant fluctuation. Not only does the magnetic north shift from its geographically defined true north, but it also undergoes complete reversals. During such reversals, previously defined poles swap positions, causing a noticeable decrease in the magnetic field's strength. These fluctuations also include magnetic field excursions, temporary states where the dipole reduces in ... read more |

Galaxies grow more chaotic over time Sydney, Australia (SPX) Apr 08, 2024 A new study led by Professor Scott Croom of the ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) and the School of Physics has demonstrated that the age of a galaxy is the principal factor influencing its increasing disorganization over time, challenging previous beliefs that mass and environmental conditions were predominant influences. This research, which meticulously analyzed data from over 3000 galaxies, discovered that older galaxies tend to exhibit more random st ... read more Melbourne, Australia (SPX) Apr 08, 2024 In a new study, scientists at the University of Melbourne's ARC Centre of Excellence for Dark Matter Particle Physics have made significant advancements in understanding dark matter by studying neut ... more |
