The corona is weirdly hot—Parker Solar Probe rules out one explanation
S-shaped bends in the sun’s magnetic field don’t form at the sun’s surface, like some scientists thought, and can’t directly heat the sun’s corona.

Explaining a supernova’s ‘string of pearls’
It looks like the same mechanism that breaks up airplane contrails might be at play in forming the clumps of hydrogen gas that ring the remnant of supernova 1987A.

Megastorms leave marks on Saturn’s atmosphere for hundreds of years
Massive storms have appeared as “Great White Spots” on Saturn every 20 to 30 years since 1876. The impacts of those older storms have lasted in Saturn’s atmosphere for centuries.

Plasma thrusters used on satellites could be much more powerful
It was believed that running more propellant through a Hall thruster would wreck its efficiency, but new experiments suggest they might power a crewed mission to Mars.
