Plasma Density Distribution in Mercury’s Magnetosphere
A new measurement of plasma density distribution in Mercury’s magnetosphere obtained from observations of field line resonance events provides necessary constraint for many planetary science issues.
Can Moderate Space Weather Have Major Impacts?
Pipeline corrosion is an example of why we need better awareness of how long-term exposure to moderate space weather may have significant economic impact by slowly degrading vulnerable systems.
New Plasma Wave Observations from Earth’s Magnetosphere
The first simultaneous observations of multiple electromagnetic wave types in Earth’s magnetosphere may inaugurate a new field of inquiry into cross-frequency wave interactions.
Magnetic Surveying Reveals Hidden Ancient Buildings and Streets
Buried buildings subtly distort natural magnetic fields, providing a magnetic surveying team with clues that helped archaeologists map an ancient city.
Jupiter’s Stressed Out Magnetosphere Causes Aurora and Heating
Force imbalance between Jupiter’s ionosphere and magnetosphere leads to wave generation to release this stress, but the waves also accelerate particles, causing aurora and heating.
Taking Magnetotelluric Data out of the Drawer
Magnetic and electric field measurements at Earth’s surface provide information on Earth’s interior and on space weather. An open-source central repository of these data has received a major update.
Forrest S. Mozer Receives 2018 John Adam Fleming Medal
Forrest S. Mozer was awarded the 2018 John Adam Fleming Medal at the AGU Fall Meeting Honors Ceremony, held on 12 December 2018 in Washington, D. C. The medal is for “original research and technical leadership in geomagnetism, atmospheric electricity, aeronomy, space physics, and/or related sciences.”
A Deeper Investment for Deep Time Science
Seven proposals recently funded by the National Science Foundation will ensure more access to laboratories that specialize in geochronology.
Measuring the Magnetic Reconnection Rate in the Magnetotail
Both simulations and observations are used to measure the magnetic reconnection rate in the Earth’s magnetotail, suggesting that the rate is correlated with the intensity of a magnetic substorm.
