[An #ENA imager headed for #Uranus?] ENAs are energetic neutral atoms produced during #collisions in hot #plasmas. They are omnipresent in space environments.

The interplanetary probes #Cassini and #JUICE carry (or carried) an ENA imager. Various #simulations reveal that such a detector aboard the #Voyager2 probe would have provided a better understanding of Uranus’s magnetospheric environment: https://www.irap.omp.eu/en/2026/05/back-to-the-future-viewing-uranus-through-an-ena-camera/

In 1942, Hannes Alfvén described a kind of magnetohydrodynamic wave in plasmas that is now named after him. #Waves #Plasmas #Alfvén (https://sharpgiving.com/Sharp/thebookofscience/items/p1942d.html)

Notes on #UAP Discussions : How would you introduce a class on "theoretical advances in novel propulsion systems " ?
if you were going to start with early history your candidates are primarily #Antigravity and #Electrostatics but a basic functional approach might start with concepts of mass levitation and associated phenomenologies like #Superconductivity, #Magnetohydrodynamics, #plasmas and #Solitons. Emphasis should be on the fact that there is more than one path to unconventional propulsion

How bacteria defend themselves against plasmas

Plasmas are used in wound treatment against pathogens that are resistant to antibiotics. However, bacteria can defend themselves. They employ a heat shock protein that protects them.
