Astronomers Come up With a New Message to let the Aliens Know we're Here - Universe Today universetoday storybywill
Jiang was joined by researchers from the SETI Institute, the Virginia Polytechnic Institute and State University, the University of Cambridge, the Hanze University of Applied Sciences, the Chevron Energy Technology Company, the School of Physics and Technology at Wuhan University, Beijing Normal University, and the University of California at Los Angeles. The paper that describes their findings recentlyA team of astronomers from UCLA searched for “technosignatures” in the Kepler field data.
The message’s destination was M13, a globular star cluster located near the edge of the Milky Way Galaxy . This cluster was believed to be a good candidate for finding intelligent civilizations since it is estimated to be 11.66 billion years old and contains approximately three-hundred thousand stars. Drake and Sagan decided to use prime numbers since they believed it would make the message easier for an alien civilization to translate.
The broadcast consisted of a 1,679-binary digit pictogram , which is the product of two prime numbers, arranged rectangularly into 73 lines of 23 characters per line . The ones and zeroes were simulated by shifting the frequency at a rate of 10 bits per second, and the total broadcast lasted less than three minutes. They conveyed a series of scientific, geographical, biological, and astronomical information in different colors.
“Following the 1974 Arecibo Message there were two transmissions made from the Evpatoria 70-meter dish located in the Crimea, Ukraine, these occurring in 1999 and 2003. The Evpatoria transmissions were overseen by a pair of Canadian researchers, Dr. Yvan Dutil and Stéphane Dumas, and were beamed at a total of nine relatively nearby stars ranging in distance from Earth of 10.1 to 21.6 parsec. The 2003 transmission utilized a more robust version of the message sent in 1999.
