Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. The above message was broadcast from Earth towards the globular star cluster M13 in 1974. This attempt at extraterrestrial communication was mostly ceremonial - humanity regularly broadcasts radio and television signals out into space accidentally. Even were this message received, M13 is so far away we would have to wait almost 50,000 years to hear an answer. Several searches for extraterrestrial intelligence are currently underway, including Project Phoenix under the direction of Dr. Jill Tarter .
