Realized Projects
These projects have targeted stars between 20 and 69 light-years from the Earth. The exception is the Arecibo message, which targeted globular cluster M13, approximately 24,000 light-years away.
The first message to reach its destination will be A Message From Earth, which should reach Gliese 581 in Libra in 2029.

Famous quotes containing the words realized and/or projects:
“I realized early on that the academy and the literary world alike—and I don’t think there really is a distinction between the two—are always dominated by fools, knaves, charlatans and bureaucrats. And that being the case, any human being, male or female, of whatever status, who has a voice of her or his own, is not going to be liked.”
—Harold Bloom (b. 1930)
“One of the things that is most striking about the young generation is that they never talk about their own futures, there are no futures for this generation, not any of them and so naturally they never think of them. It is very striking, they do not live in the present they just live, as well as they can, and they do not plan. It is extraordinary that whole populations have no projects for a future, none at all.”
—Gertrude Stein (1874–1946)
