On Jupiter, it's mushballs all the way down
Berkeley CA (SPX) Apr 16, 2025 Imagine a Slushee composed of ammonia and water encased in a hard shell of water ice. Now picture these ice-encrusted slushballs, dubbed "mushballs," raining down like hailstones during a thunderstorm, illuminated by intense flashes of lightning. Planetary scientists at the University of California, Berkeley, now say that hailstorms of mushballs accompanied by fierce lightning actually exist on Jupiter. In fact, mushball hailstorms may occur on all gaseous planets in the galaxy, including our sola ... read more |
