The Tidbinbilla Deep Space Communication Complex outside Canberra, Australia, has sent out more than 25,000 messages to Gliese 581d, the nearest Earth-like planet outside our solar system, which might host life.
According to a report carried out in www.news.com.au, the messages have come from 195 countries including some from places such as the Vatican city, Antarctica and Kosovo.
Each message, a maximum of 160 characters long, was collated on a website called “Friends from Earth” and all 25,880 messages were beamed together in a giant twitter-like message that took two hours to send.
Their target is the nearest Earth-like planet outside our solar system, called Gliese 581d, which is 20.3 light years away.
Travelling at the speed of light, or 300,000km per second, it will take 20.3 years for the messages to reach the planet and just as long for a response back to Earth.
The antenna used to transit was beaming to 302 gigawatts or the equivalent energy of 302 billion mobile phones or every person on earth sending 50 texts at one time.
Scientists believe that as Gliese 581d is four planets away from its own sun, also named Gliese 581, the conditions make it possible to contain life.
“People are really excited about Gliese 581d because they think it might have life,” Hello from Earth project manager Wilson da Silva told the gathering in Canberra moments before the transmission.
“We don’t actually know if there’s life on Gliese 581d, but what we do know is that it has the conditions for life, we don’t know that it has a technical civilization that could actually receive the signal we’re transmitting,” he said.
According to Da Silva, while some of the messages were considered inappropriate to send, others were heart-felt, like that from Aboriginal astronomer Yidumduma Bill Harney from the Wardaman people near Katherine, which read, “Our dream, we’re telling to them young kids. We’re talking all this dream for the future”.
