Last month, scientists and artists sent a message to GJ 273, a red dwarf star. The signal will be there in about a dozen of years.
The red dwarf is also known as Luyten’s star that lies 12.36 light-years from us. There are two planets in the GJ 273 system, one of which, GJ 273b, may be capable of supporting life as we know it.
Scientists at the organization Messaging Extra Terrestrial Intelligence (METI) International in the United States have sent this message, in hope of making contact with extraterrestrial civilizations. And of course, everyone expects to hopefully get a reply back.
The Luyten’s star project, known as “Sónar Calling GJ 273b,” is a collaboration involving METI International; the Institute of Space Studies of Catalonia in Spain; and Sónar, a music, creativity, and technology festival in Barcelona, Spain.
However, there are some people out there that strongly disagree with METI. One of them is the famous astrophysicist, Stephen Hawking. He is worried that beaming messages to alien civilizations could be fatal for us. Thus, he warns humanity to be wary of seeking out contact with alien civilizations.
“It’s really hard to imagine a scenario in which a civilization around Luyten’s star could have the capacity to come to Earth and threaten us, and yet they’re not able to pick up our leakage radiation,” Douglas Vakoch, the president of METI told space.com.
About the message
Team members designed the message to illustrate basic mathematical sums and they also included music by 33 artists.
Scientists sent the encoded message via ‘sonar calling,’ using pulses from a radio telescope.
The team transmitted the message out in binary code at two different radio frequencies on Oct. 16, Oct. 17 and Oct. 18. They used the 105-foot-wide (32 meters) European Incoherent Scatter Scientific Association (EISCAT) radio antenna in Tromsø, Norway.
“We focus on what we know the extraterrestrials and us have in common, if they can build a radio-telescope on any planet they need to know something as fundamental as one plus one equals two,” Dr. Vakoch told Sputnik.
