Ukraine's Space Agency Sends Message to Gliese 581c, Arrival Expected in 2029

In 2008, Earth sent a message to the exoplanet Gliese 581c, which is about 21 light-years away, and the message is expected to arrive in 2029. The message included images of celebrities and Earthlings, with the hope of making contact if extraterrestrial life exists. The earliest possible reply could be in 2050, but the likelihood remains uncertain, making it a fascinating but speculative endeavor.
