Congratulations to Heike Rauer! 🎉

I had the pleasure of experiencing her work firsthand in a colloquium at my former institute while I was still a student, and I remember her as an outstanding #planetary scientist. A very well-deserved recognition!

I seem to be in a bit of a #space mood 🪐🔭 at the moment 😅, so I remembered that I once visited the #Smithsonian National Air and Space Museum in Washington, DC and wrote a short blog post about it. I thought I would share it again here:

✨🔭 If you're interested in learning more about #SpaceScience in the region, I have two older posts about a visit I made with my former institute to the #Effelsberg #RadioTelescope ( @MPIfR_Bonn) and the #Stockert radio telescope ( #Astropeiler).

Here's the link to the Effelsberg post:

✨🔭 Interesting news from outer space: #Cassini data plus global #MHD #simulations show that #Saturn’s cusp is not noon-centered like #Earth’s, but shifted toward the post-noon and even post-dusk sector. Xu, Yao, & Arridge et al. identify 67 cusp events and argue that rapid rotation plus internal #plasma sources fundamentally reshape Saturn’s global magnetic topology:

🛰️ New paper by Knowles et al.: Using the #JWST, the authors observed rapid variability in the auroral footprints of #Jupiter’s #moons in Jupiter’s #atmosphere.

IR observations show that the footprints of moons like #Io can change on short timescales, highlighting the dynamic interaction between Jupiter’s #magnetosphere and its satellites. The moon–magnetosphere coupling driving Jupiter’s #aurora is more variable than previously assumed.

🛰️ New paper by Němec et al.: After analyzing ~10 years of #MAVEN wave data, the authors report a #lightning-like electromagnetic #whistler signal in the #Martian #ionosphere. Its frequency dispersion matches theoretical propagation through #Mars’ ionosphere and crustal magnetic fields, suggesting that electrical discharges may occur in the Martian #atmosphere.

✨🔭 New observations of #Ganymede 🌖reveal a surprising similarity between the #auroras 🌌 on the #SolarSystem's largest #moon and those on #Earth 🌍. A team of space physicists has obtained new results suggesting that the fundamental physical processes that generate auroras are common to different celestial bodies.

Using joint observations from the #Tianwen-1 in the #solarwind and #MAVEN in the induced #magnetosphere, Lin et al. identified a magnetic barrier between #Mars’ #ionosphere and shocked solar wind under the radial #IMF for the first time.

Aurora borealis visible in northeast Kansas on 11.11.25

Four (or two) second exposure with ISO 3200 on my Galaxy S20.

Aurora borealis visible in northeast Kansas on 11.11.25

Four (or two) second exposure with ISO 3200 on my Galaxy S20.

It was hard to get non-blurry shots in spite of my usual stabilization tricks because our cat Lavender kept thump-flopping against my ankles. 🙃

(Should be an even better show tonight!)

With the recent solar maximum, the aurora has been a source of dazzling displays in the night sky around the world. This week, Dr. Emma Spanswick shares an exciting new discovery related to the aurora borealis, her path to becoming a successful space physicist, her experiences traveling the world for field work and conferences, advice, and more.

Although our plasma wave data really are waves in the audible frequency range, other non-wave data may be "sonified" where different aspects of the data are mapped to aspects of audio.
