This is the exciting part: #KHI can mix magnetized and non-magnetized #plasma, drive #turbulence, transport mass/energy/momentum/ #MagneticFlux, and may contribute to small-scale #magnetic braiding, thus one route by which free #MagneticEnergy is built up in the solar #atmosphere.

That makes them relevant to the long-standing puzzle of why the #corona is heated to millions of kelvin while the visible surface is only ~5,800 K. 😎🔥

For the first time, #KelvinHelmholtzInstabilities 🌀 have been directly observed in the #Sun’s #photosphere ☀️🔭

#DKIST images reveal tiny #vortex-like structures at the edges of #MagneticFlux concentrations. #MHD simulations reproduce them and show that shear flows along these #magnetic boundaries trigger the instability.

Excellent news I: "ESA science missions get green light for new discoveries"

The Science Programme Committee discussed & endorsed the extension of the 13 missions that are due to end their current science phase before the end of 2026.

These missions are: BepiColombo, Cheops, Einstein Probe, Hinode, Hubble, IRIS, Mars Express, Proba-3, SOHO, Solar Orbiter, Webb, XMM-Newton and XRISM.

A look into the “GREGOR Observations Center” GOC at MPS Göttingen during this month’s remote campaign at the GREGOR Solar Telescope, located on Tenerife. Many great active regions and sunspots, but unfortunately clouds obstructed our view. Hoping for better conditions for our August campaign together with Solar Orbiter 🛰️ 🔭🤞

Solar prominences are massive, densely packed structures of relatively cool plasma that extend for thousands of kilometers into the Sun's exceptionally hot outer atmosphere, the corona.

"Deflector Shields Up!"

Actual things you know, not like in the movies but impressive if made to work...

Posting in the Fediverse since last week: @uksolarphysics! 🇬🇧 ☀️

The UK Solar Physics community (UKSP) is a Specialist Scientific Group affiliated to the Royal Astronomical Society. They regularly provide relevant news and nuggets both to their members as well as the international solar physics community at large via https://uksolphys.org/

If you're interested in the research of the Sun, our closest star, at all, consider following them for their announcements either at https://uksolphys.org/news/recent-news-summary/, or via their UKSP newsletter (mailing list), or now directly here via their Mastodon account @uksolarphysics

Maybe don't expect them to interact a lot, but if you *are* here for their very useful announcements, it is now really easy to follow and also boost those. So, a warm welcome to @uksolarphysics 🌞

It's Gänseliesel day in Göttingen! Freshly minted PhD graduate Johannes Hölken attended the official ceremony at the Aula, has been picked up by us and ferried to the Gänseliesel fountain in the city center, and is about to bring the goose girl on the top of the fountain some flowers. Meanwhile, other carts around us are also interesting to look at!

Congratulations! 🥳
For re-examining and improving a 33-year-old reconstruction of #solarirradiance, #mpsgoettingen scientist Theodosios Chatzistergos received the #KeesdeJagerPrize for best publication in the journal #SolarPhysics. The award was now presented. https://www.mps.mpg.de/kees-de-jager-prize-for-theodosios-chatzistergos ☀️🔭

‪Here are some great shots from our #GREGORSolarTelescope observation campaign in July. Peering into the #photosphere and #chromosphere, we caught several emerging active regions – and a #flare! This will help us study the plasma dynamics in active regions and how energy builds up to create a flare.

#ParkerSolarProbe was in the right place at the right time in September 2022: It passed through a magnetic reconnection region in the Sun's corona. #SolarOrbiter observed the event from a distance. Study led by #SwRI in @NatureAstronomy
