ISSI warmly congratulates Claire Nichols, ISSI Johannes Geiss Fellow 2026, on the publication of her new paper in Nature Geoscience: “An intermittent dynamo linked to high-titanium volcanism on the Moon.”
The study, led from the University of Oxford and based on analyses of samples returned by the Apollo program, resolves a decades-long debate about the strength of the Moon’s ancient magnetic field.
Earth’s magnetic environment is filled with a symphony of sound that we cannot hear. All around our planet, ultralow-frequency waves compose a cacophonous operetta portraying the dramatic relationship between Earth and the Sun. Now, a new citizen science project called HARP – or Heliophysics Audified: Resonances in Plasmas – has turned those once-unheard waves into audible whistles, crunches, and whooshes. Early tests have already made surprising finds, and citizen scientists can join the journey of sonic space exploration to decipher the cosmic vibrations that help sing the song of the Sun and Earth.
