JWST Discovers the Vertical Structure of #Uranus' Ionosphere: https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2025GL119304 -> Webb maps the mysterious upper atmosphere of Uranus: https://esawebb.org/news/weic2602/ - Webb provides the first vertical view of the planet’s ionosphere, revealing auroras shaped by its tilted magnetic field.

Icy or rocky? Convective or stable? New interior models of #Uranus and Neptune: https://www.aanda.org/articles/aa/full_html/2025/12/aa56911-25/aa56911-25.html -> Uranus and Neptune Might Be Rock Giants: https://www.news.uzh.ch/en/articles/media/2025/Uranus-Neptune.html - the composition of Uranus and Neptune, the two outer most planets, might be more rocky and less icy than previously thought.

The planet #Uranus ending its journey along the 14 - 13 Tauri star pair on #Xmas day (Thursday): the view from #Bochum, Germany, in the morning and in the evening - the exact moment when the three formed a rectangular triangle again, with 13 Tau the star at the right angle, was in daytime.

On January 25, 1986, Tom Bolton of the University of Toronto and Ian McGregor of the McLaughlin #Planetarium joined host Randy Attwood for a LIVE 2 hour program about #Voyager2 at #Uranus: https://www.youtube.com/watch?v=yTEim9mSiWY and https://www.youtube.com/watch?v=4OOh8e-KTOU

One week on #Uranus has now moved well along the 14 / 13 Tauri star pair, forming a wide triangle with them this evening.

The slow motion of #Uranus in just one day (24 hours ago and tonight), easily visible thanks to the current proximity to the stars 14 and 13 Tauri of similar brightness: https://www.facebook.com/planetarium.bochum/posts/pfbid0pGCePvJoCDXcnfjcPXBtmJHUNFjXYRVheG5tmuwi74w7CxdyUs48wVaaQthkfSidl - one could also see the changing shape of the triangle in binoculars!
