" But of all that he saw, what gripped him the most were the light flashes in the darkened atmosphere that he had seen before—but always high, high above him. Meteors blazing through the atmosphere, shooting stars beneath him, the fireflies of space dashing blindly through cremation. Then came the moment. Deke would never forget it. He became part of a wonder that opened all space to him. Meteors flashed in greater number than he had yet seen, the spattered debris of ancient planetary formation and collisions of rock consumed by the atmosphere of Earth. Something he could not measure in size, but unquestionably large, perhaps even huge, rushed at earth with tremendous velocity. The meteor hurtled in toward his home planet, but at an angle that would send it skimming along the upper reaches of the atmosphere, almost parallel with earth’s surface below. Deke first saw the intruder when it punched deep enough into earth’s air ocean, grazing the edges of the atmosphere with a speed he could not judge, except that it was a rogue body, gravity-whipped to tremendous velocity. It tore into thin air; instantly its outer surface began to burn, its front edges blazing like a giant welding torch gone mad. It skipped along the atmosphere and gained an upward thrusting lift, like a flat rock hurled across smooth water. Deke gazed in wonder at the sight and watched the burning invader continue its journey along the atmosphere and then flash beyond. Away now from the clutches of air, still burning, it left behind an ionized trail of particles and superheated gases. Now away from Earth, it lofted high and far until it raced beyond Earth’s shadow. Sunlight flashed through the ionized trail, and the departing mass created its own record of passage, enduring long enough for Deke to watch until the last flicker, the final gleam, was gone. He felt he should not lower his gaze. His vision moved along the arrowing path of the now invisible wanderer of the solar system, and Deke stared, unblinking, as the mass of stars in his own galaxy shone down on him, an uncountable array of suns, stars he knew were smaller than his own sun, many vastly greater in size and energy, but all members of the great pin-wheeled Milky Way of which Deke and his world were one tiny member.
