I noticed my galvanized vent pipe is disconnected. How do I reattach?
My 2 inch galvanized vent pipe is disconnected from the fitting. I don't see any threads on either the pipe or the fitting. How would I go about connecting them back together?

That is not disconnected.... that is broken.
The threads have broken off the top pipe and are now stuck in the tee fitting.
Hard to tell what is going on below the tee but some thing is pushing on that pipe
creating extreme force on the tee.

I checked the pipe it is smooth and no signs of any breakage on the end the tee has what looks like a rubber gasket inside and there is no signs of broken threads. There is the same type pipe and tee by this one and the pipe is push into the tee with support that looks like a gasket. I don't know if this is something somebody put together when they put the piping in or this something that was normally done back in the days when this 1960's house was built. What do you think?

Looks to me like that T has dropped an inch or so. You can kind of see the witness marks on the upper pipe where the tee used to connect to. That with the angle it is at now looks like whatever was supporting it below failed allowing the drop. What does the bottom pipe connect to? If it wasn't galvanized I'd think something along the lines of the old lead/oakum stuff but....

Maybe if it did drop I can pull it back on the tee and give it some kind of support or I guess my best bet is to remove the old galvanized pipe and replace with pvc. The easy part for me is installing but I dread unscrewing the old piping. Right now I am ending day 1 on trying to remove old shower piping.

The bottom pipe is going to the bathroom a floor below.

Luckily it looks like here is enough room to unscrew the T without hitting the back drywall (you'll have to hold the lower vertical pipe from turning). On the 'T' what is the horizontal pipes function/connect to?
You can also use a Sawzall, the issue will be supporting the upper vertical pipe.

I've never seen a connection quite like that before. I was on board with the snapping threads, but it's not showing any signs of rust. So I'm not really sure.
But the solution IMO is the same either way. Cut out as much of the galvanized as you can. Replace with PVC and use shielded no-hub couplings to transition from the old galvanized to new PVC. No need to try to unscrew the fittings - a sawzall is your friend.

After examining a similar connection It seems this connection uses support to hold the pipe into the tee. It doesn't seem like a good ideal as you can see if the support gives in the pipe will slide off the tee. I can only imagine how many of those connections are in my home. I will take zorfdt advice "sawzall is your friend" and use couplings. This is my 2nd day trying to unscrew the fittings and cut my hand in the process.

It would not surprise me if the installer just slipped the vent into the tee with some sort of gasket. As a vent it should not be seeing pressure. It also looks like someone tried to support the tee by wrapping some wire around it. If that's the case you might be able to pull up the tee and properly support it.
