NASA and COSMOS magazine will give us a chance to send a 160-character text message to our alien brothers and sisters on Gliese 851d on August 24 2009 in celebration of the International Year of Astronomy 2009.
Gliese 581d, just over twenty light years from us, is eight-times the size of Earth and is classified as a “super Earth” and is one the first water world candidates according to one of its discoverers Stephane Udry from the Geneva Observatory in Switzerland. Gleise 851d resides in the habitable zone of its star. Planets in this zone are just the right distance for liquid water to potentially exist.
The signal will reach the solar system of Gliese 581 (the parent star) around December 2029 give or take a few months. The radio signal will cross 20.3 light-years 192 trillion km of interstellar space before reaching the planet. If there is a response, it will probably need to travel the same way back “unless Gliesans have improved communication technologies, the soonest we could hope to receive an answer would be in 42 years around 2051,” says COSMOS.
