Solar Wind a Major Driver of Atmospheric Sodium at Mercury
MESSENGER observations show a 50% rise in atmospheric sodium-group ions during periods of high solar wind activity.
Watching the Substorms Grow
Updated procedures enable consistent use of a wide network of polar magnetometers to monitor energy flow into the tail of Earth’s magnetosphere during the growth phase of substorms.
Microbes Might Munch Magnetic Minerals at Oil Spill Site
New experiments at an old oil spill site in Minnesota suggest that nonbiological processes alone may not account for decreased magnetization.
Encontrando los océanos ocultos de las lunas usando campos magnéticos inducidos
Un análisis de componentes principales de modelos especulativos puede predecir con más seguridad que las técnicas anteriores la p^ppresencia de un océano subsuperficial en un objeto planetario.
A Step Towards Understanding the Magnetic Properties in Hematite
Scientists present the most comprehensive available magnetic domain state and anisotropy study for synthetic and natural hematite from first-order reversal curve diagrams.
New Results Deepen the Mystery of Earth’s Early Magnetic Field
How was Earth’s early magnetic field produced? New experimental results and modeling show that the energy source could not have come from exsolution of lithophile elements from the core.
Saturn’s Powerful Winds Explain Changes in the Length of Its Day
Atmospheric winds moving at more than 7,000 kilometers per hour distort Saturn’s magnetic field, revealing why spacecraft have measured changes in the length of a day on the ringed world.
Finding Moons’ Hidden Oceans with Induced Magnetic Fields
A principal component analysis of speculative models can more confidently predict the presence of a planetary object’s subsurface ocean than previous techniques.
Exploration and Evaluation of Deep-Sea Mining Sites
Two studies chart new territory for the fledgling deep-sea mining industry through advances in the identification and analysis of seafloor hydrothermal mounds.
