Tricorder Tech: Using Solid State Quantum Magnetometers To Seek Out Water Worlds
“Follow the water!” The solar system is full of water in different states, from the Sun’s water vapor to the ice of Pluto and beyond. Water is not only linked […]

MHD Simulations of the Space Weather in Proxima b: Habitability Conditions and Radio Emission
The habitability of exoplanets hosted by M-dwarf stars dramatically depends on their space weather. We present 3D magneto-hydrodynamic simulations to characterise the magneto-plasma environment and thus the habitability of the […]

Removal Of Magnetic Spacecraft Contamination Within Extraterrestrial Samples Is Easy To Do
For decades, scientists have pondered the mystery of the moon’s ancient magnetism. Based on analyses of lunar samples, its now-deceased magnetic field may have been active for more than 1.5 […]

Properties of Electrons Accelerated by the Ganymede-magnetosphere Interaction: Survey of Juno High-latitude Observations
The encounter between the Jovian co-rotating plasma and Ganymede gives rise to electromagnetic waves that propagate along the magnetic field lines and accelerate particles by resonant or non-resonant wave-particle interaction. […]

A Weak Magnetic Field May Have Supported The Diversification Of Life On Earth
An unusual reduction in the strength of the Earth’s magnetic field between 591 and 565 million years ago coincided with a significant increase in the oxygen levels in the atmosphere […]

Exoplanet Magnetic Fields
Planetary magnetic fields are important indicators of planetary processes and evolution, from a planet’s outer core to its surface (if it possesses one) to its atmosphere and near-space environment.

The Oldest Undisputed Evidence Of Earth’s Magnetic Field
Without its magnetic field, life on Earth would not be possible since this shields us from harmful cosmic radiation and charged particles emitted by the Sun (the ‘solar wind’). But […]

To Find Life In The Universe, Look To Deadly Venus
Despite surface temperatures hot enough to melt lead, lava-spewing volcanoes, and puffy clouds of sulfuric acid, uninhabitable Venus offers vital lessons about the potential for life on other planets, a […]

Cosmic Rays Streamed Through Earth’s Atmosphere 41,000 Years Ago
Earth’s magnetic field cocoons our planet from the onslaught of cosmic radiation streaming through space while also shielding us from charged particles hurled outward by the sun. But the geomagnetic […]
