Why does Antarctica have its own domain extension (.aq)?

[alexalbon23]

I stumbled upon this random fact that Antarctica has its own internet domain: .aq. I mean, it’s not like anyone really lives there, right? Turns out, it's for scientific organizations operating in the area. I’m just curious – are there other places or regions that have domain extensions that no one really thinks about? Seems like such a random thing to have!
