New Explanation for "Meandering" Electrons Orbiting Earth

Mark Zastrow, Freelance Writer

From Research Spotlights— A new study proposes a simpler theory to explain a class of electrons zipping around the Earth, propelled by magnetic explosions. In 2015, NASA launched a fleet of four spacecraft that seek out the strange physics that happen at the fringes of Earth's magnetic field..... more

Spacecraft Returns Its First Data on Martian Solar Irradiance

Sarah Stanley, Freelance Writer

From Research Spotlights— Scientists demonstrate the capabilities and limitations of the mathematical model used to calculate solar irradiance using measurements from NASA’s Mars Atmosphere and Volatile Evolution (MAVEN).  Ancient riverbeds, mineral deposits, and abundant additional evidence.... more

Untangling Uranus’s topsy-turvy magnetosphere

BLOG— New observations of Uranus being buffeted by shock waves from the sun have revealed auroral activity and fresh clues to the workings of the seventh planet’s unusual magnetosphere, the region of space dominated by its magnetic field. Mapping out the magnetospheres of planets like Earth, Jupiter.... more

Birkeland Current Boundary Flows

Editors’ Highlight— This study summarizes a statistical finding of significant velocity jets, known as Birkeland Current Boundary Flows, seen in SWARM satellite data in the northern hemisphere. The orbit configuration of SWARM allowed unique separation of spatial and temporal effects. The authors found.... more

Explaining Unexpected Twists in the Sun’s Magnetic Field

Mark Zastrow, Freelance Writer

From Research Spotlights— New research shows how the Sun’s magnetic field can shift when it approaches Earth, which can throw off space weather forecasts. Space weather forecasting requires understanding what happens when the Earth’s magnetic field meets the Sun’s. When their field lines touch,.... more

Survey of Voyager Plasma Science Ions at Jupiter: I Analysis Method

Editors’ Highlight— In our field, so much emphasis is put on the spectacular and ground-breaking, and not the fundamental work of producing high quality measurements with documentation and access to the wider community. The authors of this paper found an old data set from the Planetary Data System (NASA's.... more
