Although neither Voyager spacecraft is heading toward any particular star, Voyager 1 will pass within 1.6 light-years' distance of the star Gliese 445, currently in the constellation Camelopardalis, in about 40,000 years. 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 Voyager Golden Records are two phonograph records that were included aboard both Voyager spacecraft launched in 1977. Grade B: Contains minor imperfections i.e. The drawing containing two circles in the lower right-hand corner is a drawing of the hydrogen atom in its two lowest states, with a connecting line and digit 1 to indicate that the time interval associated with the transition from one state to the other is to be used as the fundamental time scale, both for the time given on the cover and in the decoded pictures. It shows the location of the Solar System with respect to 14 pulsars, whose precise periods are given. The drawing in the lower left-hand corner of the cover is the pulsar map previously sent as part of the plaques on Pioneers 10 and 11. A color image of the spectrum of the sun was included for calibration purposes. Color images were represented by three images in sequence, one each for red, green, and blue components of the image. A circle was used in this picture to ensure that the recipients use the correct ratio of horizontal to vertical height in picture reconstruction. Immediately below this is a replica of the first picture on the record to permit the recipients to verify that they are decoding the signals correctly. Immediately below this is a drawing of an entire picture raster, showing that there are 512 (2 9) vertical lines in a complete picture. The drawing immediately below shows how these lines are to be drawn vertically, with staggered "interlace" to give the correct picture rendition. Picture lines 1, 2 and 3 are noted in binary numbers, and the duration of one of the "picture lines," about 8 milliseconds, is noted.

The picture is made from this signal, which traces the picture as a series of vertical lines, similar to analog television (in which the picture is a series of horizontal lines). The top drawing shows the typical signal that occurs at the start of a picture. The information in the upper right-hand portion of the cover is designed to show how pictures are to be constructed from the recorded signals. Below this drawing is a side view of the record and stylus, with a binary number giving the time to play one side of the record-about an hour (more precisely, between 53 and 54 minutes). The drawing indicates that the record should be played from the outside in. Written around it in binary arithmetic is the correct time of one rotation of the record, 3.6 seconds, expressed in time units of 0.70 billionths of a second, the time period associated with a fundamental transition of the hydrogen atom. The stylus is in the correct position to play the record from the beginning. In the upper left-hand corner is a drawing of the phonograph record and the stylus carried with it.
