Which Country Artist Threw Javelin While Attending Oklahoma State University?

Did You Know!

Puerto Rico has the world’s largest radio telescope ever built before China’s FAST—the Arecibo Observatory—which, until its collapse in 2020, played a crucial role in space exploration, tracking asteroids, and even searching for alien life. But here's the twist most people don’t know:

👉 In 1974, scientists used Arecibo to send the first ever interstellar radio message—called the Arecibo Message—to potential extraterrestrial civilizations.

It was aimed at a star cluster 25,000 light-years away. The message included info about human DNA, our solar system, and even a stick-figure of a human!

So, not only did Puerto Rico house a scientific marvel, but it also holds the legacy of humanity’s first intentional "Hello!" to the stars. 🌌👽
