Coming Soon! The Arecibo Message

Coming Soon! The Arecibo Message

Check out the trailer for my upcoming episode! In keeping with the theme of major moments in SETI and METI, we’ll be looking at the Arecibo Message. Beyond being a major milestone in the Search for Extraterrestrial Intelligence (SETI), it was also humanity’s first true effort at Messaging Extraterrestrial Intelligence (METI). The coded radio message was broadcast from the Arecibo Observatory in Puerto Rico on Nov. 16th, 1974.

It consisted of a simple pictorial message of 1679 bits, arranged into 73 lines of 23 characters (both prime numbers). The message contained a graphic showing the Arecibo telescope, our Solar System, DNA, a stick figure of a human, and some of the biochemicals that make up life on Earth. The entire message lasted less than three minutes and was aimed at the globular star cluster M13, located 21,000 light-years away.

Almost fifty years later, the Message remains a focal point in the Search for Extraterrestrial Intelligence (SETI), the ethics of messaging, and why we haven’t heard from any extraterrestrial civilization (the Fermi Paradox). What’s more, a growing movement today wants to see more METI efforts in the future.

The Latest Episode of Stories from Space – The Wow! Signal – has Aired!

The Latest Episode of Stories from Space – The Wow! Signal – has Aired!

After weeks of teasers, waiting, and procrastinating, I’ve finally finished the third episode of the sixth season (S1E3). As I said before, this episode is dedicated to what remains (even after 50 years) the strongest candidate for an extraterrestrial communication. This episode was special for me because, in addition to the signal’s historical significance, I got to recount a personal story.

In 2016, when I was a relative newbie at Universe Today, I had the honor of covering some stories related to the Wow! Signal. For a few years, a professor had been claiming that the famous signal was caused by comets that were puffing out clouds of energized hydrogen. This happens when comets approach the Sun: their ice begins to sublimate, releasing clouds of water that are broken down into hydrogen and oxygen gas.

Shortly after he wrote his follow-up paper in 2017, a radio astronomer contacted us and said the whole claim was bunk. We published their thoughts on the matter, and you know what? She was proven totally right! With that one exchange, we went from being just another publication unwittingly promoting hype to writers who were in on the ground floor of a snowballing debate.
