In 1974, humanity transmitted the Arecibo Message—a 1,679-bit radio signal containing human DNA, a map of our solar system, and a human figure—using the Arecibo radio telescope toward the globular cluster M13 in Hercules, which will arrive in approximately 25,000 years.

We sent a message to the stars in 1974 #shortsAdded:
1974, humanity did something audacious.
We pointed the most powerful radio telescope on Earth at a cluster of 300,000 stars called M13. And we sent a message encoded in 1,679 bits, our numbers, our DNA, a map of our solar system, even a picture of a human being.
It's traveling at the speed of light right now. It arrives in about 25,000 years. By the time it gets there, humans may not even exist. You can find M13 yourself this June in the constellation Hercules.
