Let me guess. You are on Facebook. Or you may be on Google+. And of course, you might be on twitter as well. Why? Is there is an added sense of "existence" gained by being connected on social media platforms?
Now I have that nagging feeling that Life itself is social. If Life arises somewhere, it will attempt to interact and seek others, and it will try to interconnect.
Life is Social. This mantra goes all the way down to the very basic constituents of life itself. From cells, to DNA strands, and proteins that seem to want to snap together, curl, mingle, and interconnect. This "social" behavior seems present at all levels of emergence, it bubbles up from neurons connecting with other neurons, all the way up to an entire civilization’s yearning to detect life on other worlds.
So why haven't we made contact yet? Where are they? The answer has been staring us in the face on the first paragraph of this post. We have not found the Social Media of the Cosmos. There is no friendster, myspace, facebook or google plus for any communicating civilization to join into and interact with. We are isolated. We are on an island. We are alone. Or maybe we are just lonely.
Perhaps we should also do a Search for "Cosmic Social Media", or even better, to build one ourselves. Lately, humanity has been tweeting from space aboard the ISS, and sharing wonderful pictures of earth from above. And on a good note, NASA has been attempting to build an Interplanetary Internet, which has been known as the “Deep Space Internet”.
A galactic internet platform is hard to build unless you have a good communications medium to begin with. But what would be the best possible kind of signal for outer space? Sadly, in the vast distances involved in deep space communications, light is a limiting factor. The Electromagnetic Wave is just too slow.
How do you create an intergalactic social platform for civilizations in a universe where the speed of light limits the communication? How would advanced civilizations build their internet in space?
Sadly we haven't discovered anything from the realms of physics yet that would make a good medium for communications in the vast distances of outer space.
Perhaps our particular universe is not conducive for communicating with other advanced lifeforms because our physical laws renders the communications medium too slow. Other universes might have been luckier with their speed of light that may be faster. But not in our universe. Perhaps, each universe yields a different answer for the Fermi Paradox depending on the limits imposed upon the lifeforms asking the question.
Sure, we may find signs and biosignature of other lifeforms on other planets, but making contact with intelligent exolife would be rare.
Are we doomed to be trapped in island planets, island star systems, and ultimately "island universes"? The universe keeps expanding. Galaxies are spreading ever farther from each other. Perhaps in the far future, we would simply mingle amongst “ourselves” within our local star system--with humanoid species on Mars whose roots are from the earthkind. They'd be the migrant "humans" who eventually adapted to the properties of their homeworld. The 'aliens' will be us. And the question of other intelligent life on other star systems and exoplanets could remain with us for a very long time. Perhaps even forever.
On a positive note gleaned from the realms of fiction, imagine if we found the planet Ballybran, and extracted the ‘Black Crystal’ that makes instantaneous communication possible. Imagine if the Ansible did become a reality, and when we turned it on we heard the Cosmos alive with chatter. By then, we have joined the Social Media of the universe, and finally we are truly not alone.

Transit Light-Curve Signatures of Artificial Objects
Hot on the trail of Transit Light Curve (TLC*) Mechanics, I’d like to follow up my previous post dealing with transits by featuring this topic: Transit Light-Curve Signatures of Artificial Objects. It's a "Dysonian SETI" paper written by Luc Arnold from way back in 2005 that also mentions possible signals that might be encoded within transit light curves, and hints at the detection of ringed planets as well.
The main idea is that non-spherical objects have different light curve signatures and should be distinguishable from the usual patterns of a transiting planet.
Because hundreds or thousands of people are now looking at light curves via the Planet Hunters project, I thought it’s a good idea to post what the paper says about unusual light-curve patterns that might be caused by the transit of artificial planet-sized objects. Who knows? Perhaps the common folk hunting for planets might end up finding Civilizations as well!
So, dear planet-hunter slash civilization-hunter, start familiarizing yourself with the sample patterns I compiled below (as a quick reference) while you're classifiying light curves at PlanetHunters.org. Good luck with spotting that Kardashev Type II Civilization !!!

SETI and Kepler-4b
For some curious post to warm up a chilly monday, I just came across a surprising analysis of Kepler-4b signals not from planet-hunters, but from someone tinkering with SETI! There seems to be a "non-random" pattern that shows up in the graph. Could it be a clue to some alien message encoded within the signal?
Not too fast.
Apparently, someone who "likes analyzing signals" posted his baudline analysis of the Kepler-4 exoplanet data file from SETIquest. I'm just starting to dip my foot into Digital Signal Processing (DSP) here, but because I am interested in Data Visualization, I was drawn into it, which led me to write this quick post with lots of linktrails.
For the big question: Is there an alien message in the signal? No. There are still too many parameters to settle in order to say that it is an extraterrestrial code. But I wish to get back more into this as I am interested in finding patterns. The "spinal" pattern in the photo above seems like a good start for learning about Fast Fourier Transforms!
I downloaded the 2 Gig .dat file from SETIquest and tried to open it just to peek, but my computer almost crashed due to the humongous filesize. I wish they'd break it down into smaller bits. I'm sure SETIquest will improve in the coming days.
Many questions pop up as a result of this baudline analysis post, such as the directional source of the signal. According to the forum at SETIquest, its really from the Kepler-4 star system (but I still need a valid RA/Dec info, which was not provided in the .dat file description). Other issues need a little more work to confirm, such as whether it might have been our own artificial signals, which may include transmissions from our satellites and perhaps even signals from the Kepler telescope itself(!) Also, I think it would be great if the Allen Telescope Array will listen in on the list of star systems with known exoplanets.
There's some interesting bits of information regarding signal analysis, and bits about Kepler telescope, and some exoplanet related data files posted in the forum so check it out.
Kepler-4b is among the first batch of exoplanet discoveries announced by Kepler early this year. The host star Kepler-4 is also one of my adopted stars (ahem!) from the Pale Blue Dot project, so i took some time to look into this.
And as I mentioned in my past post about SETIquest with a quick review of His Master's Voice by Stanislaw Lem (that book was lent to me by @leebillings, by the way) the data is open for public consumption. So we can consider this post as a preview of things to come between the intersections of Planetary Science, Astronomy, SETI, Exoarchaeology(?), Citizen Science, and just plain ol' geekiness.

Brainwave 2010: Is Life Out There?
It was a beautiful day, and perhaps many were more interested in getting some sun as there were less people this time than the previous brainwave event I attended. This time it was rock musician Claire Evans of Yacht and Fred Adams author of The Five Ages of The Universe.
When the Director of the Event, Tim McHenry introduced the duo, i just learned that Claire Evans actually has a blog called Universe, and Tim started the event by showing the 60-sec animation created by Claire about the evolution of life. Then she began the conversation by introducing the Fermi Paradox.
The speculations that followed included the notion that Life is common, but intelligence is rare.
Claire is cognizant of the fact that we dont know enough just yet about the makeup of extra-terrestrial lifeforms, speculating--for example, about a "sentient cloud" and then wondering how to best detect them. However Fred says that we don't know anything better than using radio astronomy for SETI just yet, and so that is the method we currently use.
Claire likes the Hypothesis that some Advanced Technological Civilizations (ATC) know that we exist, but they dont want to touch us--in line with the "Prime Directive" in Star Trek, ATCs must not bother with developing civilizations.
As the duo continued to explore the solutions to the Fermi Paradox, they moved on to bleaker scenarios such as the inclination of Technological societies to destroy itself. Or various naturally occuring cosmic events such as Supernovae could explain why no civilization ever lives long enough to meet everyone else.
Fred mentions the idea that we're literally living in a supernova bubble--that supernovae have been a few parsecs away around our sun's neighborhood in the distant past.
Somehow this alerted Claire to mention speculations of how earth might die, such as getting yanked out of orbit by a passing celestial object. She says she might find the scene beautiful, how the atmosphere would snow down on earth, as the planet freezes the surface dwellers to death. She added that among the survivors would be the creatures around the deep underwater vents.
Fred adds how a watery planet would be in the cold outer part of a solar system. It will have a frozen outer shell, but internal heat would cause liquid water beneath.
And since Fred mentioned that the "Holy Grail" of SETI is the discovery of a technologically advanced civilization, Claire asks what would it mean if extra-terrestrial life were found.
Fred answers that its a gamechanger...but creationism wouldn't go away. Fred mentions though, a "lesser" Holy Grail, in the form of developing the ability to create synthetic life in the lab. Claire asks Fred "Do you believe in Technological Singularity?" since she herself finds it hard to believe. Fred answers by saying that ours is a young civilization and we might engineer our survival. Fred mentions the idea of moving the earth by a bit outwards (i think he meant gravity traction) via an asteroid. The gradual outward migration of Earth's orbit will hopefully match the swelling of the sun and move outwards to the expanding habitable zone to prolong life on this planet. Finally, among other feats of hypothetical Astroengineering, the Dyson sphere was mentioned, of course.
As the Q&A portion ensued, I happened to be picked to ask the third question. After a gentleman asked about Kepler and it's discoveries, Fred was optimistic that the Earth-like discovery will come very soon (if not this year). I followed up by asking what the impact of the discovery of an Earth-like planet will be to the human culture.
Fred answers that the impact of the discovery of an earth analog on human culture will be modest. Though, it will be on the front page of the New York Times, he adds. Claire says it takes much more than an earth-like planet to rouse the masses as people generally doesn't care much about these things. It will be the discovery of Life on these worlds that will have much impact on humanity.
Tim asks what scifi film exemplifies SETI best. Claire mentions "Contact". Fred, still in the technological frame of mind from answering a previous singularity question, says he likes "Bladerunner". Science fiction was briefly discussed among the audience, mentioning how scifi mirrors our hopes and anxieties in terms of a technological future.
Tim wraps up with a question on the future of our universe. Fred shows a few slides of new findings about our cosmic future, how the accelerating expansion of the cosmos will isolate galaxies, and result in "island universes", rendering all hopes of communicating with other galaxies impossible as light will never reach from one to the other.
The point of contact seems bleak in terms of gigayears ahead. And even now, the prospect of finding any extra-terrestrial signal may seem to be a hopeless endeavor if you take the negative stance.
The key I suppose, is to keep asking, and to keep searching. Perhaps there really is something incredible out there just waiting to be known.

SETI's Quest and His Master's Voice
A few weeks ago, by coincidence, some news came while I've been reading "His Master's Voice" by Stanislaw Lem. It turned out that the SETI Institute will open up its data to "Citizen Scientists" via SETIQuest. The data collected by the SETI Institute will be opened to the public for anyone to analyze.
It all made me curious about our reactions if a message from the stars were discovered hidden within the SETI archives. I cant help but think that some of the things that occured in Lem's novel might actually happen. The government might assemble a team of scientists to specifically study this message from the stars. Various experts such as Mathematicians, Astronomers, Astrophysicists, Astrobiologists might be gathered and isolated in a remote location to decipher the message. And of course, the military and other covert agencies will secretly be studying the data with a different purpose in mind. Now Stanislaw Lem writes in a way that makes it all seem like His Master's Voice (HMV) was a real story. It was so much fun to read, that it often made me chuckle.
During Stanislaw Lem's time, he saw a kind of Science that is marked by covert operations, and secret projects perpetrated by a government more concerned with warfare. But now we live in a wonderful time in history where the common folk can get involved in pure Scientific pursuit. The technological advances, and the opening up of massive data now allow anyone to donate their time, skills, and resources for noble purposes. This is the era of Citizen Science and it comes at a perfect time to support the aim of the SETI project as well.
Check out SETIQuest for ongoing developments in the Search for Extra-Terrestrial Intelligence and make sure you join the effort. We might find another "voice" from way out there! And if it doesn't happen in our time, just remember that it is worth the effort to keep searching, exploring and learning. It's all part of the journey and adventure to find our place in this Cosmos.

Life is a Pattern
"Life is a pattern." He whispered in an epiphany of realization as he gazed at the patchwork of visualizations displayed on the walls of his control room. Inside the room was an amazing view of a menagerie of extrasolar planets, exomoons and hypothetical microbes and extremophiles that may thrive on the planetary environments. This was a facility doing research on Planetary Science and Astrobiology.
The control room tapped a powerful cloud computing grid with a database that tracked thousands of extrasolar systems. Parameters for the simulations are updated by planet-hunting teams from around the world. Information such as planetary mass, type of planet, distance from the host star, orbital period, chemical make-up, atmospheric density and so on, were fed into a powerful AI software running in the cloud. It's aim was to virtually "find" exolife even before it was discovered in the real world. It was the largest open collaboration of Astronomers, Astrobiologists and Astrophysicists ever set up, and backed up by the leading Computer Scientists.
Throughout the years of manning the control room, Dalro Villaramas has garnered some insight to come up with a solution that might revolutionize the way to search other forms of life. The secret, he thought was to view life in a new way. He was certain that his idea would expand the methods to detect life into other platforms beyond the water-based or carbon-based forms that we know of. He rubbed his hands together excitedly as he decided that he was going to start writing an ArXiv paper. He was going to tell the whole world about it.
Suddenly, he was startled by his manager who barged into the room as he spoke hurriedly, "Dalro, there's a new planet that was detected. Its nothing that's ever been found in history..."
"Hey that's great! But...why do you look so...grim? Are you ok?"
It was odd, very different than the usual when he informs him of new exoplanet discoveries. Instead of the bright sparkle in his eyes, it was glazed. He proceeded, "...please run a simulation of how it would affect the planets in our solar system...earth..."
"What?! Did we just find a new planet in our solar system?"
"Yes...and, no. The planet is now within our solar system but it came from somewhere else. As we speak, a rogue planet--a Planemo is barreling its way toward our Sun. Amateur Astronomers just detected it after it entered our heliosphere and showed signs of its presence. The parameters are being fed into the grid in real-time. Start the process now and feed the results back to the global network. Please hurry, we don't have much time..."
Dalro hammered on the keyboards and directed all computing resources to this job. In a few minutes, the walls were filled with a view as if from a spaceship's cockpit looking down at the solar system. The 'hypervelocity' Planemo was travelling so fast, way too fast.
For the next few minutes, the simulation showed what would happen--most of the planets would be disturbed from their orbits. The massive planemo would miss Pluto but disturb the Kuiper belt scattering thousands of rocks. It would graze close to Neptune, and hemmorhage Uranus, and distort the rings of Saturn. As it wobbles Jupiter, several moons would be yanked out. Then he gasped as he saw the spheriod rock dig deeper in the solar system. Earth and it's moon would be flung from orbit in a slingshot effect--out into interstellar space.
The alarm sounded in the background. The commotion was now starting to stir other countries around the world. The earth was shaking.
Dalro was now alone in the room. He stood watching the simulated view of the Earth as it made its way out into the cold, dark empty space. The simulation stopped.
He closed his eyes. Images of all his loved ones flashing in his mind, fading with images of Earth--frozen in mid-chaos.
"Life is a pattern..." he whispered as he started to shiver. The temperature was dropping too fast. Darkness fell. Then silence.

Space Alone
A great story! 'Space Alone' is a great tale for future explorers of exoplanets (exoplorers), and for those who search for life in space.

The Extremophile Zone (EZ)
Judging from the fact that the Habitable Zone (HZ) is such a narrow region around a star or a galaxy, the difficulty in searching for planets and life around such areas calls for an alternative route:
I simply propose that we "consider" life in a region that we can call, The Extremophile Zone (EZ).
Any area that lie outside the Habitable Zone can potentially be an Extremophile Zone. Introducing this concept will expand the venue of our efforts in the search for life.
You see, we are at a kind of stand-still right now in where we aim to find life: Liquid water at the Goldilocks Zone. It is a major guide in the search for life but it is out-of-reach for those who do not have the specific instruments, or the right kind of telescopes.
Perhaps a different approach may prove to be fun and imaginative at the same time. Instead of snobbing exoplanets that are not within the habitable zone, we could instead appreciate them more and then postulate the "extreme" forms of life that may thrive on each new-found world (small "bubbles" of Habitable Zones may even exist within extremophile zones).
A web-based system can be built that stores updated exoplanetary data and then also accept ideas from enthusiasts, amateurs and professionals about what type of extreme life could survive on each world if it did manage to start up. This "proactive" system would then be a mix of crowdsourcing, web2.0/social media, gaming, and an expert system, or AI. (See how the Fold.It, and GalaxyZoo is facilitated).
It's somewhat of a different flow than the usual search for life. This method will bank on sheer numbers of factual data, plus a massive input of theory and imagination, a creative dose of fun, and an ingenious system to crunch it all into 'diamonds'. In time, with some fuzzy logic and Science, perhaps it may produce useful insights regarding life on future exoplanet discoveries.
Imagine a database of a thousand exoplanets each with a hundred ideas--honed via web2.0, social media, or even peer review--on how life may thrive on it. And then imagine a system that will mix-and-match ideas with the properties of the newest exoplanet discovery. I think it will produce a valid insight and might give Astrobiologists some new biomarkers to look for. It may even form another loop in scientific research.
A thousand exoplanet count is not too far off (we have a total of 349 as of this writing). Perhaps next year we'll reach that milestone.
Now imagine ten thousand worlds and the brain of a HiveMind+AI thinking about life on those worlds. The possibilities are enormous. And if such a system ever materializes in the future, then it will make every exoplanet discovery as precious and important as the ones that lie in the Habitable Zone.

Instead of snobbing exoplanets that are not within the habitable zone, we could instead appreciate them more and then postulate the "extreme" forms of life that may thrive on each new-found world (small "bubbles" of Habitable Zones may even exist within extremophile zones).
A web-based system can be built that stores updated exoplanetary data and then also accept ideas from enthusiasts, amateurs and professionals about what type of extreme life could survive on each world if it did manage to start up. This "proactive" system would then be a mix of crowdsourcing, web2.0/social media, gaming, and an expert system, or AI. (See how the Fold.It, and GalaxyZoo is facilitated).
It's somewhat of a different flow than the usual search for life. This method will bank on sheer numbers of factual data, plus a massive input of theory and imagination, a creative dose of fun, and an ingenious system to crunch it all into 'diamonds'. In time, with some fuzzy logic and Science, perhaps it may produce useful insights regarding life on future exoplanet discoveries.
Imagine a database of a thousand exoplanets each with a hundred ideas--honed via web2.0, social media, or even peer review--on how life may thrive on it. And then imagine a system that will mix-and-match ideas with the properties of the newest exoplanet discovery. I think it will produce a valid insight and might give Astrobiologists some new biomarkers to look for. It may even form another loop in scientific research.
A thousand exoplanet count is not too far off (we have a total of 349 as of this writing). Perhaps next year we'll reach that milestone.
Now imagine ten thousand worlds and the brain of a HiveMind+AI thinking about life on those worlds. The possibilities are enormous. And if such a system ever materializes in the future, then it will make every exoplanet discovery as precious and important as the ones that lie in the Habitable Zone.

Planetary Art Installations
Springtime is almost here, and as the weather continues to warm I will have a chance to tag along with a friend named Petty who often roams the art galleries of New York. His marathon to visit as many "gallery openings" as possible within two hours is quite fun, moreso that the primary method of hydration is free wine and beer. Sometimes I would come across some art installations that would just often trap me glassy-eyed staring at them as I hold my fifth glass of red wine.From a cosmic perspective, there is plenty of free booze (energy) in the universe. And I assume that 'life' would arise from booze, such as "us" to consume it. Then I would like to hypothesize that there would be cosmic art installations as well from these restless beings.
For example, Advanced Technological Civilizations could "sprinkle" specific crystals to fashion artificially-created or modded rings around planets to create planetary works of art, or perhaps use nanobot dust to create animated rings.
Natural planetary rings are a true beauty, but there's no telling how the creatives would use nature's idea as an inspiration to make something new. Creativity can never be contained, thus planetary-hacking might just be a matter of time.
Aside from the aesthetics behind such a planetary exhibit, I can only deduce that it must be cleverly designed to provide an obvious mark that it was created artificially and that it was done having art or self-expression in mind. I am assuming that the sense of artistry and creativity is inherent in sentient beings, with the capacity for interstellar travel for the advanced ones.
It would be a stretch to try to imagine how beauty would be expressed by advanced civilizations, but one thing I can speculate is that their art installations probably have a mathematical aspect woven into it, perhaps some code embedded in the ring patterns.
Or perhaps it would be so striking as to be banksy.
Or perhaps it would just be so plain nonsensical that we would immediately recognize it as artificially made, in which case we might consider it as cosmic vandalism.
Exoplanets are so numerous that they lend themselves unwitting targets for planetary artistry and vandalism. Dressing up planets would almost be mundane for anyone who have mastered space travel.
In Manhattan, never have I seen so many art galleries in one area. They are packed in such a way that you may be able to graze more than 10 of them on foot in a span of one hour.
Perhaps there is a stellar "city" somewhere in the Milky Way, hustling and bustling with the myriad of "life". Our star is located in the outskirts of the galaxy and our nearest neighbor is about 4 light years away, Alpha Centauri. Maybe we are in the galactic countryside, and there are no art galleries or art installations nearby, yet.
But our neighborhood is still a galactic city in the making. Some few hundreds of years from now our own solar system will be bustling with interplanetary activity. And perhaps then we will see a glimpse of planetary art installations in our neighborhood. Jupiter? Saturn? Neptune? Perhaps Venus with artificial rings! We can only imagine.
As for those advanced beings out there that got an earlier evolutionary headstart, they have yet to exhibit their presence. And if so, Fermi asks the classic question, "Where are they? Where could they be?"
Why, they're in the "city", of course--mingling and drinking booze!

SETI's Way of Celebrating Science & Imagination
The SETI Institute is located at 515 N. Whisman Road, Mountain View CA 94043.
Did I happen to mention that some people from Spore will be there?
