Scientists have developed a new message that could be beamed to intelligent aliens that might exist in the Milky Way, reports Scientific American.

The new spacebound note, named the Beacon in the Galaxy (BITG), is the latest in a series of attempts to contact other lifeforms in the universe that date back to a message sent in 1974 from Puerto Rico’s Arecibo telescope to a star cluster.
