Where are the Voyager spacecraft headed and what might they encounter next?

In this video on the UK-based V101 Science YouTube channel they ask the musical question: "What will Voyager 1 and 2 encounter next?"

Next stop for Voyager 1? An obscure red dwarf known as Gliese 445 in the constellation Camelopardalis. It will take the then long-dead spacecraft over 38,000 years to get there. Voyager 2 is hellbound in the direction of Sagittarius and will arrive in the neighborhood in some 40,000 years. Its first encounter will be with Ross 248 in the constellation of Andromeda.

Of course, we all know what's really going to happen to at least one of these probes. It's going to be picked up by a highly-evolved machine race and turned into the heart of a vast killer plasma cloud that will return to our solar system and try to destroy Earth.
