It rains on the Sun! Although not in any way we’d recognise from Earth. In the Sun’s corona, the superheated atmosphere that extends millions of kilometres above its visible surface, cooler blobs of plasma occasionally form and fall back downward in what astronomers are calling coronal rain. Until now, the mechanism behind the rain has remained a mystery especially during solar flares where it seems to accelerate but researchers at the University of Hawaii Institute for Astronomy have finally cracked the puzzle.
