See the Solar Wind

After a solar prominence erupts, strong solar winds flow outward from the sun, carrying energetic particles that can disrupt satellites and trigger auroras if they make their way toward us. In this video, an instrument onboard the ESA/NASA’s Solar Orbiter captures the solar wind in the aftermath of such an eruption. The features seen here extended 3 solar radii and lasted for hours. The measurements give astrophysicists their best view yet of this post-eruption relaxation period, and the authors report that their measurements are remarkably similar to results of recent magnetohydrodynamics simulations, suggesting that those simulations are accurately capturing solar physics.

#Sun might be spitting out particles that create water on moon
"With only #lunar soil and a basic ingredient from the sun — which is always spitting out #hydrogen — there's a possibility of creating water."
In 2016 scientists found comet debris vaporize on impact, creating shock waves in lunar soil which can sometimes breach the dry upper layer, releasing water molecules from the hydrated layer below.
