Life as we know it will end one day, but the key to finding alien life—and humanity’s last hope for survival beyond Earth—is already out there.

According to a new video from the educational channel Kurzgesagt, the last star left in the universe will probably be a red dwarf. It has a lifespan of approximately 10 trillion years and burns out more slowly than other stars—such as the sun itself, which only has about 1 billion years left.

Red dwarfs also exert enough energy to support a system of planets (but only if you’re within the right distance of it), giving humanity a possible viable option once Earth can no longer support us for trillions of years. But if a red dwarf makes it possible for us to inhabit another planet, what’s to say one isn’t already doing that for other lifeforms?
