Are aliens listening? Scientists Make Message to Send Earth's Location to Aliens.
Scientists have designed a radio message to be beamed into deep space that reveals Earth's location, which they hope will be received and understood by an intelligent alien civilization.
The message is essentially an updated version of the famous Arecibo message, transmitted in 1974, which had the same purpose. Broadcast from the Arecibo Radio Telescope in Puerto Rico, the message consisted of 1,679 bits arranged into 73 lines of 23 characters.
The team of scientists wants to broadcast simple principles for communication, basic mathematical concepts, physics formulas, constituents of DNA along with information about humans, the Earth, and a return address if someone wants to revert.
While the 1974 broadcast was designed by Cornell astronomy professor Frank Drake along with physicist Carl Sagan, the latest endeavour is being led by Dr. Jonathan Jiang from the Jet Propulsion Laboratory.
Astronomers have long worked to identify intelligent life in the Milky Way galaxy. However, results have not been promising. Nasa has detected over 5000 worlds in our own galaxy with the possibility of conditions that could support life.
Researchers say the message should be beamed out on either March 30 or October 4, when the Earth is at an optimal angle and should be sent from the SETI Institute’s Allen Telescope Array in California or the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China.
