Sounding Rockets Probe the Northern Lights Above Norway

Emily Underwood, Freelance Writer

Research Spotlight— Scientists measure how the aurora affects winds in the upper atmosphere. When a dazzling aurora lights up the polar skies, it’s a sign of a disturbance in Earth’s magnetosphere, the magnetic shield that protects our planet from solar radiation. The aurora borealis and aurora australis—also.... more

A Close-in Look at Saturn’s Periodic Space Bubble

Mike Liemohn, Editor-in-Chief, JGR: Space Physics

Editors' Highlight— When it comes to Saturn’s space environment, summer wins over winter in controlling the periodic flows of electrically charged particles and magnetic fields. In 2017, the Cassini spacecraft ended its orbital tour of Saturn, its moons, and its space environment. At the end, as it.... more

Where the Solar Wind Meets Mars

Mike Liemohn, Editor-in-Chief, JGR: Space Physics

Editors' Highlight— A comprehensive look at how the solar wind is diverted around Mars, including the relative strength of the three biggest forces at work in this region. Mars, without a strong internal dipole magnetic field, is a place where the supersonic solar wind directly contacts the planet’s.... more

Jets of Ionospheric Cold Plasma Discovered at the Magnetopause

David Shultz, Freelance Writer

Research Spotlight— The lower-energy particles may play a larger role in magnetic reconnection than previously believed, influencing space weather near Earth. The Sun and Earth both produce powerful magnetic fields, and their intersection creates a complex system of physics that determines the space.... more

The “Magnetic-less” Magnetotail Boundary

Mike Liemohn, Editor-in-Chief, JGR: Space Physics

Editors' Highlight— Most boundaries in space are governed by magnetic fields, but not far behind the Earth, where the field change across the magnetopause plays very little role in the pressure balance relationship. Space physicists like to focus on regional boundaries that are magnetized. Artemyev.... more

Tracing Electric Currents That Flow Along Earth’s Magnetic Field

Sarah Witman, Freelance Writer

Research Spotlight— A new study uses satellite data to examine a worldwide system of electric currents in greater detail than ever before. The fact that planet Earth is essentially a giant magnet is not a great secret: A compass works because either end of its magnetized needle is constantly being drawn.... more

Probing the Cusps of Saturn’s Magnetic Field

Mark Zastrow, Freelance Writer

From Eos.org: Research Spotlights— Data from the Cassini spacecraft show that the cusp regions of Saturn’s magnetic field—where it connects to the Sun’s magnetic field—have similarities to Earth’s and also intriguing differences. Some of the most hotly debated regions of Earth’s magnetic field are its.... more

New Findings from Old Data

Editors' Vox— We are approaching the 40-year anniversary of the two Voyager spacecraft making their 1979 flybys of the planet Jupiter. Jupiter’s magnetosphere is big. The satellites were moving fast, and each one only spent a few days passing through the magnetic bubble around this planet so two flybys.... more
