Microbes Likely Form Magnetite in the South China Sea
Researchers sampled sediment cores and found that where magnetite was abundant, methane-producing bacteria were as well.
Open-Source MAGPRIME Supports Space Magnetism in the Heliosphere
MAGPRIME is a library of magnetic interference removal algorithms, including benchmarks, that can aid in the design of spacecraft by providing simulations to determine optimal magnetometer placement.
Studying the Mystery of Uranus’s Curiously Weak Radiation Belts
The belts may not be weak at all—instead, they may be simply changing speed thanks to the planet’s asymmetric magnetic field.
A Magnetic Low May Have Paved the Way for Complex Life
Multicellular life blossomed when Earth’s magnetic field was at an all-time low.
The Not-So-Quiet Cretaceous Quiet Zone
A new study finds that Earth’s magnetic field intensity varied significantly during the Cretaceous Normal Superchron, providing insights into the operation of the geodynamo during superchrons.
Magnetic Barriers Might Explain Mysterious Hot Jupiters
Hot Jupiters might end up very close to stars because a magnetic field halts their progress—and future observations could confirm the idea.
GAD is Enough!
An exhaustive study in China finds no need to invoke extreme true polar wander nor anomalous geomagnetic fields in the early Neoproterozoic.
Introducing the New Editor-in-Chief of JGR: Planets
Learn about the person taking the helm of JGR: Planets and their vision for the coming years.
Greenland Could Have Records of 3.7-billion-year-old Geomagnetic Fields
Scientists argue that paleomagnetic field tests preserve a geomagnetic field record acquired as chemical remnant magnetization in banded iron formations in southwest Greenland.
