This pulsar is represented by the long line pointing down and to the right. Rounding this off at about 10 significant bits (100000110100000000000000000000) would have provided a hint of this uncertainty. The map lists the period of this pulsar in binary to much greater precision: 100000110110010110001001111000. When the plaque was designed, the frequency of pulsar "1240" (now known as J1243-6423) was known to only three significant decimal digits: 0.388 second. The data for one of the pulsars is misleading. Showing the location with as many as 14 pulsars provides redundancy so that the location of the origin can be triangulated even if only some of the pulsars are recognized. If the plaque is found, only some of the pulsars may be visible from the location of its discovery. A tick mark at the end of each line gives the Z coordinate perpendicular to the galactic plane. The lengths of the lines show the relative distances of the pulsars to the Sun. Since these periods will change over time, the epoch of the launch can be calculated from these values. Fourteen of the lines have corresponding long binary numbers, which stand for the periods of pulsars, using the hydrogen spin-flip transition frequency as the unit. The radial pattern on the left of the plaque shows 15 lines emanating from the same origin. Relative position of the Sun to the center of the Galaxy and 14 pulsars with their periods denoted Kraemer, however, the original design that was presented to NASA headquarters included a line which indicated the woman's vulva, and this line was erased as a condition for approval of the design by John Naugle, former head of NASA's Office of Space Science and the agency's former chief scientist. Second, Sagan believed that a design with such an explicit depiction of a woman's genitalia would be considered too obscene to be approved by NASA. First, Greek sculptures of women do not include that line. Sagan said that the decision to not include the vertical line on the woman's genitalia ( pudendal cleft) which would be caused by the intersection of the labia majora was due to two reasons. It has been claimed that Sagan, having little time to complete the plaque, suspected that NASA would have rejected a more intricate drawing and therefore made a compromise just to be safe. The woman's genitals are not depicted in detail only the Mons pubis is shown. The original drawings of the figures were based on drawings by Leonardo da Vinci and Greek sculptures. Originally Sagan intended the humans to be shown holding hands, but soon realized that an extraterrestrial might perceive them as a single creature rather than two organisms. Although this gesture may not be understood, it offers a way to show the opposable thumb and how the limbs can be moved. ![]() The right hand of the man is raised as a sign of good will. In the replicas from the 2017 Kickstarter campaign mentioned above the delineation is correct. It probably dates back to a printing error in the original article "A Message from Earth" which is the primary source for many of the copies of the engraving. The small defect in the first zero is only in reproductions of the plaque (like here) and not on the original. In units of the wavelength of the hyperfine transition of hydrogen this means 8 × 21 cm = 168 centimetres (66 in). Between the brackets that indicate the height of the woman, the binary representation of the number 8 can be seen (1000). On the right side of the plaque, a nude man and woman are shown in front of the spacecraft. Symbolism Hyperfine transition of neutral hydrogen
