On October 9, 2008, a message from earth (AMFE) was sent by Ukraine's State Space Agency towards Gliese 581c. The message, a digital time capsule, contains 501 messages which was sent using the RT-70 radar telescope of Ukraine's State Space Agency. The estimated time that the signal will reach the exoplanet will be in early 2029.
During the studies, they found out that the planet is tidally locked; it has the same side of the planet facing the object it is orbiting.If there is a chance for life to survive, the best hope for its survival is the planet's terminator or twilight zone.
