  1. Listen and Communicate with Intelligent Life Richard B, Chad H, Stephen G

  2. How do we want to be remembered?

  3. Early Broadcast Attempts • 1820: Carl Friedrich Gauss - reflecting sunlight towards the planets, giant triangle in the Siberian forest • 1840: Joseph von Littrow - light a 30 km wide canal ablaze with kerosene • 1869: Charles Cros - use a parabolic mirror to flash messages • 1974: Frank Drake - First radio message "Arecibo Message" • Gold plates on Pioneer 10 and 11 • Golden record on Voyagers 1 and 2 • Social Network Bebo broadcasts 501 user submitted messages • Cosmic Calls 1 and 2

  4. Arecibo Message Broadcast on November 16th 1974 from the Arecibo radio telescope. Aimed toward globular star cluster M13. M13 is 25,000 light years away.

  5. Our base number system Numbers in binary Start marker 1 2 3 4 5 6 7 8 9 10

  6. DNA Elements H C N O P Atomic Number 1 6 7 8 15

  7. Nucleotides H C N O P Deoxyribose Adenine Thymine Deoxyribose Phosphate Phosphate Deoxyribose Cytosine Guanine Deoxyribose Phosphate Phosphate

  8. Double Helix DNA Pictorial representation of double helix. 2 middle rows represent approx. 4.3 billion in binary to represent number of nucleotides.

  9. Humanity Middle: Representation of a human Right: Human population Left: Average human height

  10. Solar System Give location of earth and general not to scale size representation.

  11. Telescope Top section is a pictograph of the telescope emphasizing the parabolic shape Bottom 2 rows communicate the telescopes diameter

  12. SETI (Search for Extraterrestrial Intelligence) •1960 – Frank Drake •1960’s – Soviets •1970’s – American Astronomers •1992 – NASA’s Ames Research Center –Jet Propulsion Laboratory •1995 – SETI Institute •Project Phoenix •Allen Telescope Array •1999 – UC Berkeley SETI@home

  13. H.E.Y. Message 43 X 135 3 Radio Frequencies Visual, Informational, and Musical Compartments

  14. Why Radio Waves? Radio Waves have a long wavelength Dust in space or atmospheric conditions can decay short wavelengths more easily. Insignificant radio background. Cosmic microwave radiation is 7.35 cm.
