Efforts To Search For, Send Messages To Extraterrestrial Life Advance In Digital Age

• In 1977, NASA scientists installed a golden record on two space probes that were part of the Voyager Mission. On each copy were dozens of images, sounds from nature, and multiple greetings in 55 different languages. The record also contained music from around the world, and included classical as well as a recording of Chuck Berry’s “Johnny B Goode.” “This was a way of telling another civilization about us,” explained the legendary astronomer and astrophysicist Frank Drake.

• Drake and fellow astrophysicist, the late Carl Sagan, also wrote what’s known as the Arecibo Message in 1974, the first interstellar radio message sent from earth to a globular star cluster known as M13 in hopes that extraterrestrial intelligence could receive and decipher it.

• Drake and Sagan also designed what is known as the Pioneer plaques. These plaques were another kind of message from earth that scientists hoped would be intercepted by extraterrestrial beings from the 1972 Pioneer 10 and the 1973 Pioneer 11 spacecraft missions.

• In 2015, Russian billionaire Yuri Milner unveiled a project called the “Breakthrough Initiatives” to search for extraterrestrial intelligence over the span of at least 10 years. Part of the Initiatives program includes a $1M Breakthrough Message competition, where the task is to design a digital message to send to advanced civilizations. But no message has yet been sent. And some, such as Doug Vakoch who heads up: Messaging Extraterrestrial Intelligence (METI), want to send the messages now and hear back from other civilizations. He explained that the messages would be sent by radio or in the near future, by lasers using very brief laser pulses.

• Not everyone agrees we should be rapidly concocting and sending messages. Stargazer Alicia Adams says, “I’ve seen Mars Attacks and that ended horribly!” Retired Professor of Astronomy Andrew Fraknoi says it’s a question over which space scientists are now grappling. “If we’re going to be deciding to advertise our presence to the universe, we should have a discussion with the rest of the world,” said Fraknoi. “Are we ready to signal out there that we on earth exist? We are barely getting along with each other. Are we ready to get along with aliens?”

• Drake thinks intelligent beings already know we’re here due to television and radio signals traveling in space. “It’s too late, folks. We’ve made our presence known big-time,” said Drake.

• A recent survey by Glocalities involving 24 countries found nearly half of all humans believe in extraterrestrials.

 

An ambitious new effort is underway to make direct contact with intelligent life beyond earth, improving upon 70s-era space missions which included attempts to bring messages from Earth to extraterrestrials.

For centuries, we’ve gazed up at the stars, and wondered are we alone? Some say it is time to move more aggressively and find out.

In early April, NASA’s newest planet hunter called the Transiting Exoplanet Survey Satellite (TESS) discovered its first Earth-sized alien planet. A recent survey by Glocalities involving 24 countries found nearly half of all humans believe in extraterrestrials.

ETs are on our mind. At the California Academy of Sciences in Golden Gate Park, an entire evening’s event was all about extraterrestrials. A special dance troupe performed to an eclectic mix of sounds. The sounds were excerpts taken from a famous golden record, intended for intelligent life in the universe. The 12-inch copper gold plated disk is known as the Pioneer Golden Record.

Artist Katerina Wong choreographed the performance and was thrilled to know its history.

“They were hoping if there was an opportunity to meet an ET, that they would get a little bit of understanding about what life on earth was like.” remarked Wong.

In 1977, NASA scientists installed a golden record on two space probes that were part of the Voyager Mission.

On each copy were dozens of images, sounds from nature, and multiple greetings in 55 different languages. The record also contained music from around the world, and included classical as well as a recording of Chuck Berry’s “Johnny B Goode.”

According to NASA, the Voyager 1 and Voyager 2 are exploring where nothing from Earth has flown before. Their primary mission was the exploration of Jupiter and Saturn in our own solar system but now, both probes are billions of miles away from earth – carrying a message from earth on these golden records. The hope was that somewhere beyond our solar system, intelligent life or advanced civilizations will find them and be able to decipher their contents.
“This was a way of telling another civilization about us,” explained the legendary astronomer and astrophysicist Frank Drake.

44 Years After Its First Message to Aliens, Arecibo Observatory Calls For Follow-Up

by Alan Boyle                     November 16, 2018                         (geekwire.com)

• In 1974, the first Arecibo Message transmitted from the Arecibo Observatory in Puerto Rico was designed by SETI astronomers including Frank Drake and Carl Sagen and was beamed by radio transmission from the Arecibo telescope in the direction of the M13 star cluster in the constellation Hercules. It was meant as an intergalactic greeting from planet Earth.  (see image of message below)

• The shapes shown on the Arecibo Message grid represent a variety of concepts ranging from the numbers 1 through 10 to the chemical constituents of DNA, our solar system’s planets and the telescope itself, plus a stick figure that stands for humanity. Other types of messages have been sent out periodically since then as well.

• Since the first transmission was sent in 1974, the three minutes’ worth of radio waves have rippled out to a distance of 44 light-years, or less than 0.2 percent of the way to M13 star cluster. Experts acknowledge that it’s extremely unlikely the message will ever be detected and decoded by an alien civilization.

• Now the Planetary Habitability Laboratory at the University of Puerto Rico at Arecibo Observatory wants to transmit a second Arecibo Message from Arecibo’s 1,000-foot-wide radio telescope. They’ve announced a student-focused competition to design a new message to beam to extraterrestrials. In order to qualify and ultimately register, student competitors will first need to solve a series of brain-teasing puzzles posted on Arecibo’s website. The contest is open to teams from around the world, in classes ranging from kindergarten to college. Each team should consist of five students plus an adult mentor – for example, a teacher, professor or professional scientist. The first challenge will be posted on December 16th. Clues and follow-up activities will be rolled out periodically over the next year, and the winning team is due to be revealed next fall during a celebration of the Arecibo Message’s 45th anniversary.  (see 1:08 minute video below)

• Experts continue to debate the wisdom of broadcasting our existence to the rest of the universe. Most famously, the late physicist Stephen Hawking said letting extraterrestrials know where we are could turn out as badly for us as Christopher Columbus’ arrival in the New World turned out for Native Americans.

 

The Arecibo Observatory today kicked off a student-focused competition to design a new message to beam to extraterrestrials, 44 years to the day since the first deliberate message was sent out from Arecibo’s 1,000-foot-wide radio telescope.

“Our society and our technology have changed a lot since 1974,” Francisco Cordova, the observatory’s director, said in a news release. “So if we were assembling our message today, what would it say? What would it look like? What one would need to learn to be able to design the right updated message from the earthlings? Those are the questions we are posing to young people around the world through the New Arecibo Message – the global challenge.”

It’s not just about the message, however: Competitors will have to solve brain-teasing puzzles posted on Arecibo’s website in order to qualify, get instructions, register and submit their designs. Along the way, they’ll learn about space science, the scientific method and Arecibo’s story.

“We have quite a few surprises in store for participants, and we will be sharing more details as the competition progresses,” Cordova said.

The contest is open to teams from around the world, in classes ranging from kindergarten to college. Each team should consist of five students plus an adult mentor – for example, a teacher, professor or professional scientist. The first challenge will be posted on Dec. 16.

The 1st Arecibo Message

“Teams should wait until the release of the first challenge on December 16, since they will need to solve that challenge to be able to register,” Abel Méndez, director of the Planetary Habitability Laboratory at the University of Puerto Rico at Arecibo, told me in an email. “Meanwhile, team leaders should subscribe to the Arecibo newsletter for updates and start forming their own teams.”

Clues and follow-up activities will be rolled out periodically over the next year, and the winning team is due to be revealed next fall during a celebration of the Arecibo Message’s 45th anniversary.
