Be a Voyager, exploring of the universe, while wearing this 1.25" version of the plaque on the Voyager spacecrafts.
What the symbols mean:
In the upper left-hand corner is a drawing of the phonograph record and the stylus carried with it. The stylus is in the correct position to play the record from the beginning. 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 drawing indicates that the record should be played from the outside in. 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 information in the upper right-hand portion of the cover is designed to show how pictures are to be constructed from the recorded signals. The top drawing shows the typical signal that occurs at the start of a picture. 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). 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 drawing immediately below shows how these lines are to be drawn vertically, with staggered "interlace" to give the correct picture rendition. Immediately below this is a drawing of an entire picture raster, showing that there are 512 (29) vertical lines in a complete picture. 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. A circle was used in this picture to ensure that the recipients use the correct ratio of horizontal to vertical height in picture reconstruction. Color images were represented by three images in sequence, one each for red, green, and blue components of the image. A color image of the spectrum of the sun was included for calibration purposes.
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. It shows the location of the Solar System with respect to 14 pulsars, whose precise periods are given. 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.

I just kinda found this shop and boy! am I glad I did! Love this shop immensely & immediately! The pins are well made with significant sciency facts illustrated, and trivia thrown in. The dinosaur pins are beautiful. Excellent enamel work and detail! Overall just a real fun store with great artistry everywhere! Thank you! Peace ☮️
would like to thank Stemcell Science Shop.
i ordered the Voyager pin Grade A. through a mishap i received Grade B in the mail and it's journey to me left it with a smashed over stem with the pointed tip broken off.
i contacted Stemcell and they immediately corrected the error and shipped the correct one in a stronger packaging.
the pin is more beautiful in person and exceeds what i expected, honestly.
thank you again,
Tim Emerich
