A Space Hurricane over the Earth’s Polar Ionosphere

Hurricanes in the Earth's lower atmosphere are well-studied, but none have ever been detected in the upper atmosphere. Here, we show a long-lasting hurricane in the polar ionosphere and magnetosphere with surprisingly large energy and momentum deposition despite otherwise extremely quiet geomagnetic conditions.

Investigating the Moon’s Interaction with the Terrestrial Magnetotail Lobe Plasma

In this paper, we provide the first detection of a plasma wake behind the Moon when located in Earth’s magnetotail lobes and measure a hidden, low-energy ion population that may be associated with outflow from the terrestrial ionosphere. We identify characteristic features of the lunar plasma interaction in this environment, and draw comparisons to various moons in the outer solar system. Read more.
