segments focused on enduring astronomical phenomena, while the regular weekly episodes focused more on time-sensitive information about current sky events. Evergreen segments were generally longer than the one-minute length of the regular weekly episodes, although usually shorter than five minutes. Unlike the regular weekly episodes, the evergreen segments were not intended for broadcast during any particular calendar week and could therefore be broadcast at any time due to the fact that their subject matter lacked expiration dates. Generally, the format and appearance of the evergreen segments resembled that of the discontinued five-minute format of the regular weekly episodes. Content The show educates viewers about astronomical events for the coming week and about astronomy and astronomical history in general. Viewers learn about various constellations and how to find different stars. Horkheimer used catchy phrases to help viewers remember the procedures for locating astronomical bodies. "Arc to Arcturus, speed on to Spica", was a common phrase used to define the technique to find Arcturus and Spica using the handle of the Big Dipper.

The Pleiades, also known as the seven sisters, was a constellation he would tell stories about.

In 1997, specific shows were made when Mars Pathfinder landed on Mars and when the spacecraft Galileo orbited Jupiter, both of which were major headlines in the news. The show has many catchphrases that viewers associate with Horkheimer. Horkheimer's appearances on the show are always marked with his opening line, "Greetings, greetings, fellow star gazers!" and his signature closing line, "Keep looking up!" These are the most widely recognizable quotes from the show but there were also others in common usage throughout the series. Horkheimer used "So get thee outside..." to encourage viewers to watch the stars. When describing the heavens he would often say "Let me show you." When introducing a picture of the night sky, he would often say, "O.K., we've got our
