tl;dr: Microorganisms used to live without oxygen. Some organisms started sprewing oxygen. Oxygen killed off most of these oxygen-free microorganisms. Life evolved and adapted. There's this lake in which the bottom layer is oxygen-less and oxygen-free microorganisms exist there. Scientists are doing a bunch of studies of this ecosystem.

I wouldn't call those organisms "alien." They were first in this planet!

And lethal...

I mean, sure. We'd deserve it for striking first.

Edit: I misunderstood your comment. I see it now :)

My bad. I meant the "lethal" in the title. Title makes it sound as if a deadly pandemic happens if that lake thaws.
