New info about 3I/ATLAS, NASA tests a new high-power ion engine, did dark matter power early black hole formation, why is half the Milky Way hotter than the other? And in Space Bites+, different sources for two of Uranus moons.

It must be powerful if Magneto is involved. 🥳 > "A lithium-fed magnetoplasmadynamic (MPD) thruster solves the primary drawback of traditional ion engines (which use heavy gases like xenon): low thrust. It achieves this by using electromagnetic forces rather than high-voltage grids, making it fundamentally faster and more powerful."
If haven't spoken then I sugges speaking to ex0-moon ressearcher Dt Davig Kipping, I think he teaches at Columbia Uni, his YT has 1 million+ subs now. Good content.
Hey Frasier, been watching for years. Great resource, thank you so much for your work. I was wondering if we have any idea where 3/I Atlas same from? How far back can we run trajectory calculations before gravitic uncertainty overwhelms accuracy?
Great job as always! So often I discover things here that it wouldn't have occurred to me to ask about. PS I've been rethinking some of my online content support but not yours, except perhaps to increase it. 👍✌️
