Space weather isn’t referring to rain clouds that float through the galaxy. Instead, it’s caused by massive explosions of particles that shoot out from the Sun.

It rains on the Sun, the gigantic thermonuclear orb that burns with the multi-million-degree 'fires' of fusion. This rain is made of superheated plasma, and researchers might have discovered its secret: quickly shifting flows of elements such as iron,

Scientists at the University of Hawaiʻi have discovered why it rains on the Sun. Solar rain, made of cooling plasma, forms rapidly during solar flares, a mystery now solved by modeling time-varying elements like iron.
