Cthulhu...In...SPAAAAACE: Science Fiction

She was staring at the radar readings, more than a little confused to pick up something the shape of an octopus with horns...if that octopus was the size of Texas and rapidly heading towards earth. "Um, boss?" she said, watching the display warily, as if it might change the instant she took her eyes away. "I don't know if somebody's playing a joke on me here, but I think you should see this. Now." Her boss strode over, took one look at the screen, and spun around and ran to the wall, where he pushed a large blue button under a large "Do Not Touch" sign. Then he picked up the telephone from the desk nearby and, without dialing a number, said, "Case Cthulhu is active. Repeat, Case Cthulhu."

Inspiration: A woot.com t-shirt marked with an octopus with horns.
