"Space inspires awe and wonder but it also can be scary… and lethal," reads the show's official description. "Supermassive black holes, deadly gamma-ray bursts, rogue asteroids, dark energy, supernovas… Our world is under attack from above. It's like a ticking time bomb." Gillen steps in as the detective tasked with solving a different case every episode, but first, he needs evidence.

The Wire alum is aided by a "mysterious informant," investigating each disaster-in-the-making with the help of a "wide range of experts" who have spent their lives studying some of science's most unbelievable wonders. Six cases face our hero in Killer of the Cosmos: dark stars, death rays, little green men, killer rocks, cosmic scrap and the big sleep. Each of these cases features a different deadly danger lurking deep in space, leading the investigation to one conclusion: "Earth is in the firing line. It's not a matter of if these things will strike, but when!"
