ELI5: Why did the 2009 meteor impact leave a "hole" in Jupiter's gas surface? Shouldn't it just close up again?

I know it has a solid core, but what about the gaseous top layer? Also, with the density of the interior of Jupiter, is the meteor still "stuck" inside Jupiter?

Jupiter is big.  Really, really, really big.  Its diameter is more than ten times that of Earth.  The Red Spot alone is bigger than Earth.

The hole in Jupiter's atmosphere did close up.  But it was so big (the hole was as big as the Pacific Ocean) that it took a significant amount of time for the gases to fill it up again.
