In the not-so-distant future Ken Kee, the dynamic developer of the Astro Streak system, devises a technique to use laser cannon and cosmic ray bombardment to make artificial aurorae around the Earth and to use them for communication, display, and entertainment. A visionary president encourages him to develop the technique and to expand it to the other planets. When all the planets have their aurorae, the display attracts the attention of the galactic aliens. Earth is finally in communication with outside intelligent life and has the chance to join the intergalactic community.
