What do helium balloons do long after you let them go into the sky?

Depends on how full they are... as they rise, the outside pressure decreases, and - this expands the balloon, so... they can pop.
Or, they can float in the breeze, and eventually lose their internal gas, and drop back to Earth.

Either (a) they expand until the skin of the balloon ruptures or (b) the helium, being much smaller than most other gases (AND monatomic) would just leak out until the balloon would no longer be buoyant.

If the Helium does not leak through the envelope (rubber) then it expands as it rises and --POW! the balloon bursts, releasing the gas and falling to the ground.

What does this have to do with astronomy and space?

Helium balloons leak helium. The helium probably goes right through the rubber or escapes through the knot. Then the balloon will fall from the sky.

Eventually they deflate, then fall back to Earth. More pollution.

They will keep flying around until their balloons hit something that breaks them, the helium will escape Earth, because it's such a lite gas, and the damaged balloon falls somewhere on the ground, adding to the pollution. That's also a reason some people say we should not let up thousands of balloons just for entertainment. They cause a lot of environmental issues, trash, fish eating parts of it, all and all not a good idea.
