Breaker One-Nine, SOS, FRB’s & ETs


Dot dot dot-dash dash dash-dot dot dot. Dear readers, do you know what that is? It is SOS in Morse Code. All radio operators know this. It is an understood code that crosses all language barriers. The gringa, fascinated with all things space, then has to ask, does this include extra-terrestrials? Well, who knows?!

Now, the SETI Institute (Search for Extra-Terrestrial Intelligent Life) doesn’t really make it a practice to emit signals in their search for ETs, rather, they listen to outer space “noise”. NASA’s search for extra-terrestrial life isn’t so much for little green men to have a conversation with, but, rather, the origins of life such as amino acids, ribonucleotides (RNA) and certain gases such as oxygen, methane, ammonia, hydrogen, and, of course, water.

However, Earthlings have been inadvertently sending out all sorts of signals into space for over five decades. As technological devices fill the Earth, transmission signals fill the heavens: radio broadcasts, television signals, radar blips and bleeps, etc. So, why do we not purposely send a message designed to create a favorable first impression rather than let all this mish-mash represent humankind? Does NASA and SETI believe that no one exists, thus no one is listening or do they believe there may be inherent danger in seeking out contact? Evidently the reason is because there is no consensus, yet, within the scientific community. The professionals are ARGUING. Hmph.

Douglas Vakoch, a researcher with SETI, thinks that it may be time to have an international discussion on the subject and let the public’s opinion on the matter be heard. He is on the pro-sending signals side of the argument. He proposes transmitting radio signals to hundreds of stars within eighty-two light years of our home planet. This can be accomplished with the radio telescope at Arecibo Observatory in Puerto Rico.

Renowned physicist, Stephen Hawking, on the other hand, thinks this is a bad idea. By sending out so many signals to every Tom, Dick and Harry alien out there, we could communicate with the good, the bad and the ugly. He believes we should be much more cautious in our approach.

So, it seems that, although there is no consensus within the scientific community on whether or not we should initiate communication, there is a consensus that somewhere out there is intelligent life that would not only receive the signals, but would be capable of responding, perhaps in person. The gringa says, “Hmmm.”

Now, the telescope at Arecibo has already sent a space message back in 1974. Consisting of an intricate code, it was transmitted to a cluster of stars 25,000 light years away.

The Crimeans sent out four messages to the cosmos from 1999 until 2008. They were transmitted from the Yevpatoria RT-70 radio telescope at Crimea’s Center for Deep Space Communications. Their ET messages were entitled: “Cosmic Call”, “Teen Age Message”, “Cosmic Call 2”, and “A Message From Earth”. The messages were made up of binary code, repeating signals, musical compositions, photographs, whale songs, etc.

Scientists believed that it is important to purposely beam thoughtful messages into deep space rather than let ETs believe all Earthlings are like the Kardashians, or the Zodiac killer, or Archie Bunker. Although Earthlings have been flooding outer space with signals since the beginning of the television era, most of our daily technologies do not have signals that are sufficiently strong enough to be picked up by our nearest living ET neighbors’ light years away. Although, if they are advanced enough, they have probably detected something by now.

So, if SETI and the Crimeans have already sent out some transmissions, the gringa then wonders, “What’s the big deal about sending more?” And, if our own daily barrage of digital signals and radio waves have the possibility of already being detected, what’s the point of “laying low”? If an ET civilization is super advanced to the point they could easily dominate us, yet they haven’t shown up and taken over, why be so worried? It seems they could care less.

The gringa thinks the real reason why the scientists can’t stop arguing and just get to the business at hand is an age old reason. Power struggle. Tsk, tsk. How disappointing. The gringa believed that surely, of all human beings, scientists were above such nonsense. As scientists consider the possibility of the most ground-breaking and historical event EVER playing out, they eye one another suspiciously and wonder just who is going to get the credit. Yes. Exactly who gets to devise the message, approve it and send it as the representative of the entire Earth?!

So, although there are researchers who want to open up the subject to public debate, that also opens it up to the general host of problems that goes along with human nature. Venturing into the area of communicating with an alien race would mean the establishment of protocols. Who gets to decide who we Earthlings talk to and what we talk about?

Although SETI wants to actively transmit in hopes of communicating with extra-terrestrials, the official policy of the institute is that the final decision belongs to the people of Earth. Such a decision affects all humans. It could be the single-most life affecting decision for mankind. Therefore, it should be left in the hands of all the people and not just a few “experts”.

Many other leaders in the space exploration community are in agreement, such as former Senior Scientist for Astrobiology in NASA’s planetary protection office, John Rummel and SpaceX founder, Elon Musk. Pioneering American astronomer, Geoff Marcy, who has discovered many “extrasolar” planets, believes it is important that every culture, even deep jungle indigenous peoples, upon Earth have the opportunity to have their voices heard in such a decision that will affect every person worldwide.

The discussion on this issue will probably continue to heat up because, recently, some interesting radio signals have been detected by astronomers who have been left scratching their heads and wondering if they could, perhaps, be a signal from intelligent beings, seeing that, like one of our own repeated signal transmissions, this signal also repeated itself.

If a repeating signal has been detected in deep space, could it have other origins than intelligent beings purposely transmitting? Canadian scientist Paul Scholz finds the mystery rather exciting and believes this to be an important discovery and wants to know if the signals originated with living, breathing ETs or if a star just went “kaplooie” and it’s just a “coincidence” that it created a shockwave noise that mimics a man-made (or little green man-made) artificial, repeating signal.

Until the signals began repeating, scientists theorized the rapid bursts of radio signals resulted from a star that went supernova and exploded or, perhaps, a neutron star collapsing into a black hole. But, now that the signals are identical and repeating, the same scientists don’t quite know what to think.

In addition to a repeating pattern, there are other singular differences that set the signals apart from other space “noise”. When studied further, the signals are “brighter” and in a different “spot” on the “spectrum” of other fast radio burst signals (FRBs). These details are all well and good, but all the gringa wants to know is, “Are we alone or not?”

The closest I can get to a straight answer is what a Cornell University astronomy professor has to say. According to Professor James Cordes, whatever charge is powering the signal, it is powerful enough to repeat the signal cycle within minutes. The energy packed behind the transmission must be impressive because they are extraordinarily bright, thus enabling us to see them from very, very, very, very, far away. And, the power source must also be incredibly secure and amazingly strong and durable because it is not destroyed by the transmission of an exploding-star-scale blast and is capable of repeating the exploding-star-scale blast.

To put all of this in a nutshell, five fast radio burst signals were captured by the Parkes radio telescope in New South Wales, Australia. Rather than just be a single burst of energy, these are double bursts, two bursts separated by 2.4 milliseconds, consistently. They repeated five times. The origins of the signals could be as far away as several billion light years beyond the Milky Way Galaxy, our home turf in the cosmos.

The gringa has no answer and remains intrigued. And my vote is that we send our own signals.

The Case Of The Hitchhiking Microbe


What, exactly, does NASA hope to accomplish if astronauts really do set their boots on the surface of Mars? One thing they hope to discover are clues to the origins of life on Earth. The gringa asks, “What exactly does that mean?” It means that NASA is considering the theory of “panspermia” and is exploring outer space to see if stellar evidence proves this theory to be true.

Panspermia is nothing new.  As far back as 5BC scientists were considering panspermia as the explanation for how humans came into existence here on Earth. In 1871 it was officially proposed in the scientific community of that day. Panspermia posits that it is possible for life to planet hop, possibly even hop among star systems, and seed the planets it visits with life. In a nutshell, that would mean that the primitive biological material that evolved into the original ancestors of humans was not created here on Earth, but, rather, were alien hitchhikers who made their way here on cosmic fragments.

NASA’s exploration policy is to “follow the water” because it is necessary to produce life as we know it. Water is found throughout the universe, just not in the form we need, liquid. It’s usually frozen. However, wherever there is frozen water, perhaps, in that planet’s history, it was once liquid. And, if so, perhaps that is where human origins can be found if the panspermia theory is true, that life exists in the universe and can travel via meteors to other planets and eventually develop on other worlds where the environment is sufficient to support its development.

Since Mars was a warm world with water long ago, the necessary ingredients for life as we know it, it makes it a logical planet to explore for evidence of panspermia. The exploration and data collected so far from the rovers and satellites studying Mars have been limited to studying the surface of the Red Planet. No evidence has been found on the surface. It is possible, however, that important evidence could be buried beyond the reach of the rovers’ digging capabilities or a satellite’s imaging. That is why it is important to get some human explorers out there.

What would the implications be if Earth-like microbes were discovered on Mars? Every human would first want to go have a very long look in the mirror and then a very long look up into the heavens and ponder the concept. NASA, however, would not be surprised. NASA has already conducted studies on over 130 meteorites from Mars and determined that none contained any microbial evidence despite the fact that some claims to the contrary were made. NASA understands the serious repercussions that would occur around the world if such a discovery is made and we can trust them to report the truth without any hype. NASA takes scientific truth seriously.

They even have a program established that studies the effects such discoveries might have throughout the world. They understand that an announcement that extraterrestrial life exists will have serious philosophical, religious, legal, ethical and cultural implications that will impact people all over the world.

Despite NASA’s interest in this theory and their willingness to explore space with the idea in mind to search for supportive evidence, they are also realistic about its probability. They believe that it is probably unlikely that life as we know it on Earth was seeded from Mars origins. However, because science is not about “probably”, they must continue the studies until the theory can be proven or disproven.

There are some scientists who do believe that Mars was an ideal place for life to have existed at some time. They believe that since such life would have existed long before life on Earth ever existed, it is then not unreasonable to consider the possibility that microbes traveled to Earth on a meteorite and introduced life here on the Blue Planet.

One reason some scientists support the idea of panspermia via Mars is because Martian meteorites contain the precursors to RNA, boron and molybdenum. In fact, they contain more of these two elements than what is found in early Earth. And why does that matter? RNA is a molecule that plays a critical role in regulating genes and its presence is necessary for all life forms as we Earthlings know them. So, if an old rock from Mars contains such a molecule, it only stands to reason, at least from an Earthling perspective, that it existed on Mars for the purpose of regulating the genetic codes of some Martian life form.

Another Martian discovery that further supports the belief that life once existed on Mars has to do with phosphates. It has already been established that Mars has provided evidence of the presence of RNA. In order for RNA to form, phosphates must be present. Well, not only does Mars have phosphates, but Martian phosphates dissolve in water much better than Earth’s phosphates. The logic then goes that since life as we know it here on Earth originated in water, Martian conditions were even more friendly to the aspect of life forming than conditions on Earth. So, if it could happen here, it most certainly should have happened on Mars.

So, basically, the theory goes that about 4 billions years ago a comet or meteorite of Martian origins blasted through our galaxy and slammed into Earth. Now this could have been an accident or, according to “directed panspermia” theory, a deliberate action by an intelligent civilization.

Historically panspermia has been considered “fringe” science. However, it is now gaining new consideration in light of the Mars mission. In fact, in 2013 Professor Chandra Wickramasinghe of the University of Buckingham claims to have discovered fossilized remains of organisms in meteorites found within Earth’s atmosphere. This proves that it is possible for primitive life forms to survive the intense heat of entry into Earth’s atmosphere and make its way to Earth’s surface. He believes it is possible that the entire Milky Way Galaxy could have been teeming with life at one time long, long ago. He also believes that organic, possibly even living, stellar material is constantly being exchanged throughout the cosmos through meteoric impact.

So, the gringa awaits the exciting mission of boots on the ground on Mars. I eagerly await the drill, baby, drill action that will delve deep below the dusty surface of the Red Planet. I can’t wait to find out what may lie beneath the frozen crust of the vast Martian ocean. Scientists believe the Martian seas are not frozen solid. Could a Martian “Nessie” be swimming about waiting for visitors to come feed her a few breadcrumbs? It very well could be. And, she could be our distant cousin.
