Capturing Heat-Driven Atmospheric Tides on Mars
Spacecraft observations and model simulations provide new insights into tidal patterns that transport momentum and energy into the planet’s upper atmosphere.
Terrestrial Radio Signals May Suppress High-Energy Electrons
Naval radio signals may cause the formation of a barrier observed during geomagnetic storms that is seemingly impenetrable by relativistic electrons.
Successfully Simulating Atmospheric Gravity Waves
These waves are key to moving energy from the troposphere to the thermosphere, but until now they haven’t been well described at high altitudes in computer models.
First Model of Meteoric Nickel in the Upper Atmosphere
A layer of nickel of cosmic origin, which exists between 80 and 110 km high in Earth’s atmosphere, has been modeled for the first time, including dynamics and complex neutral and ion chemistry.
Upstream Propagating Magnetic Dips in the Magnetosheath
The previous consensus that magnetic dips in the magnetosheath can be attributed to non-propagating mirror waves is now shown to be oversimplified.
New Energetic Neutral Atom Emissions from Jupiter, Io, and Europa
The first Jovian off-equator Energetic Neutral Atom viewings reveal distinct emissions from Jupiter and the orbits of Io and Europa: Energetic particle injections surprisingly occur inside Io’s orbit.
“Electron Wings” Can Interfere with Spacecraft Measurements
Spacecraft sometimes produce a form of electrical self-interference as they zip through plasmas in space—a previously unreported effect that may be lurking in old data sets.
Using a Machine to Help Us Learn About Jupiter’s Aurora
A first usage of principal component analysis on Hubble images of Jupiter’s auroral ovals reveals the most common patterns, and machine learning classification reveals their physical causes.
Charging Thunderclouds Affect Ionospheric Conductivity
As thunderstorm updrafts strengthen, electrification of clouds can heat the lower ionosphere, explaining prolonged disturbances to radio waves in the rarefied atmospheric layer.
