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.

The Holy Grail in Exoplanet Science

A couple of weeks ago, I enjoyed a great evening of exoplanets, music, cocktail and science at the SciCafe Event which launched with a topic about Exoplanets and the Search for Life in the Universe.

Ben Oppenheimer's lecture and presentation was stylish and unique. A 3D map of the known exoplanets around our stellar neighborhood was shown in multiple widescreens scattered across the museum space. He gave some background on adaptive optics, coronal shields (coronagraphy) and spectography. He showed animation clips across the different wavelengths of light seen from a star: the resulting animation is a function not of time but of color. He also gave a hint that soon he will release some new findings they gained using their technique.

The whole aura during the event was simply hip and cool. Just imagine sipping red wine inside the American Museum of Natural History (Rose Center) with some ambient music while being immersed in planetary stuff. Of course, seeing some twitter friends, @leebillings and @bnroberts at the event was nice. And did I mention that I wore my nerdy Kepler shirt and a beautiful woman commented on it? "Nice shirt!" she said, nodding in approval.

After the lecture, during the Q & A portion I kept raising my hand for the last question but I wasn't picked. But I was glad that Ben picked someone else who asked an excellent question, "What is the Holy Grail in Exoplanet Science?"

And I appreciated the answer I heard: For Ben Oppenheimer, the Holy Grail in Exoplanet Science is simply being part of it. He says that the Holy Grail is not making the best exoplanet discovery and being in the news and in the papers. The Holy Grail is simply being part of the collective efforts of a myriad of people that revolves around the Science of Exoplanets. Ultimately, he says, Exoplanet Science will be done by society as a whole. Now that's the Holy Grail of Exoplanet Science. Amen!

Serendipity and Imagination

Karl KofoedA very cool bookstore called Imagine Atrium in my area is closing, and it's a very sad thing indeed. To show our support, my wife brought the whole family to take part in the last Poetry Reading session at the store. The kids loved it and we all had a blast.
I say that everyone must experience the magic of Poetry for it encompasses many of the great facets of humanity.
After the event, I looked around the store for discounted books to buy and I chanced upon a gem: Galactic Geographic Annual 3003 by Karl Kofoed. It's a highly graphic sci-fi book that set my mind careening in outer space and into the future. How it jives with the theme of Exoplanetology is unmistakeable. It touches upon Exobiology, Exoplanetary science and some bit of Archeo-Astronomy and Astrophysics intermixed with intriguing settings of futuristic fiction that might actually come true, someday.
My imagination was truly set ablaze with this find.
Karl Kofoed's art is truly masterful. I wonder how his paint strokes can evoke visions of the future. It is a work of art. And I am glad that Serendipity has given me a book to power my Imagination.

Forecast: A Deluge of Exoplanets To Be Discovered in 2008




This is the Golden Age of Exoplanetology and Planetary Science. For this year, we might see at least more than 60 new Exoplanets yet to be discovered before the end of 2008. The chart shows the number of exoplanets discovered each year.
With Planet-hunters getting better and better at their craft of planet-detection, armed with better telescopes at higher and higher resolutions, and more powerful data-crunching computers, there's no reason why the planet-hunters would score lower than last year's 60 exoplanet discoveries. As of writing, we currently have 3, but as more and more amateur astronomers are jumping in on the hunt, we will see an explosion of new extrasolar planets to be added in the Exoplanet Catalog, and more planet-hunters to be added in history!
The big fish is a small rocky earth-like exoplanet somewhere in the habitable zone. I am hopeful that at least one of them will be snagged this year.
So what are you waiting for?! Let's join the hunt!
