DELTA PER (Delta Persei). Dominated as it is by its two brightest stars, Mirfak and Algol (Alpha and Beta Persei), the next four stars of glorious Perseus, the mythical rescuer of Andromeda, are often ignored. This quartet, which consists of Gamma, Delta, Epsilon, and Zeta, are all nearly the same mid-third magnitude brightness, and add great sparkle to the northern constellation.

The Voyager Golden Records are two identical phonograph records one of each which were included aboard the two Voyager spacecraft launched in 1977. The records contain sounds and images selected to portray the diversity of life and culture on Earth, and are intended for any intelligent extraterrestrial life form who may find them. The records are a time capsule.
