  • October 19th, 2017 was a day like any other-  

  • until it wasn't. High on a mountain topHawaii's Pan-STARRS1 telescope scanned the skies,  

  • searching the solar system fordeadly threat to life on earth.  

  • As part of NASA's Near-Earth Object Observations  program, the telescope was updating its catalogue  

  • of near-earth asteroids and comets which could  pose a threat should one impact us. However,  

  • Pan-STARRS1 discovered something much more than  a dangerous asteroid, and according to a growing  

  • community of academics, it may have discovered the  first verified proof of intelligent alien life.

  • Whizzing by at a breakneck speed of 196,000 miles  an hour (87.3 km per second), Oumuamua's highly  

  • elliptical orbit immediately told astronomers  that they weren't looking at an ordinary comet  

  • or asteroid- this was the first confirmed visitor  from outside our solar system. As telescopes of  

  • all kinds pointed at our interstellar visitor  though, the data only became... weirder.

  • Radar showed us that Oumuamua was a very  strange object indeed. Up to a quarter mile  

  • long (400 meters), Oumumua is ten times longer  than wide, resembling the classic UFO cigar shape  

  • often claimed by witnesses- only on a much more  massive scale. To date no similar natural object  

  • has ever been witnessed in space around  the earth, neither comet or asteroid.

  • As Oumuamua- which in Hawaiian means 'the  scout'- sped out of our solar system however,  

  • scientists spotted it doing something  no natural object should be doing:  

  • accelerating. Any object falling towards the sun  is expected to accelerate as the sun's gravity  

  • pulls on it, but as Oumuamua swung past the  sun and was on its way out of the solar system,  

  • scientists spotted it moving in a way that  wouldn't be expected from gravity alone.

  • Scientists were quick to hypothesize that if  Oumuamua was indeed the remnant of a comet,  

  • it could simply be outgassing as the sun's  rays heat up its body. Outgassing is the  

  • result of a cometary body warming up in  the sun, leading to the release of gas-  

  • the escaping gases and debris acts much  in the same way a rocket engine does,  

  • albeit on a smaller scale. It was a simple, and  very routine solution to the Oumuamua mystery-  

  • except it didn't fit, because try as they mightscientists could find no evidence of outgassing.

  • A new theory was quickly proposedOumuamua was simply venting solid hydrogen,  

  • invisible to us- but that  theory was quickly rebutted  

  • as being completely impractical in the  real world. Theory came and theory went,  

  • but none could offer a widely accepted answer  for Oumuamua's acceleration. Except for one.

  • Harvard astronomer Avi Loeb looked at the  data and proposed a stunning solution:  

  • Oumuamua was an alien ship  being propelled by solar sails.

  • The acceleration witnessed by Oumuamua was very  slight, but exactly the type of acceleration we'd  

  • expect from a very large ship using a massive  solar sail. This type of interstellar propulsion  

  • method uses extremely thin sheets of material set  either to the front or sides of a spacecraft. The  

  • 'sails' work in the exact same way that wind sails  do here on earth, only with solar radiation rather  

  • than wind. While miniscule, the impact of photons  on a solar sail imparts a tiny bit of momentum  

  • which over long spans of time can accelerate  a ship to a very respectable fraction of the  

  • speed of light. The best part is that unlike  regular rockets, you don't have to carry the  

  • weight of your fuel with you, and as long as you  can dip near a star you'll never run out of fuel.

  • Solar sails aren't the fastest means of  interstellar propulsion humanity has theorized,  

  • but they are extremely efficient. It'll  take Oumuamua about 11,000 years to travel  

  • one light year as it speeds away from us  and towards the Pegasus constellation,  

  • and while that sounds like a very long time, the  truth is that for an intergalactic civilization  

  • those sorts of time scales are irrelevant. While  not likely a research ship of any kind, as manned  

  • ships would want to move faster than Oumuamua, it  could have very well been an automated cargo craft  

  • dipping into our solar system for a speed  boost as it slingshotted past our sun.

  • There is one problem with this though, and that's  the fact that Oumuamua was believed to be tumbling  

  • on more than one axis- which wouldn't make much  sense for a functional alien ship. However,  

  • a derelict or destroyed ship, or perhaps  simply a piece of massive alien debris,  

  • could easily be spinning on multiple axis the  way Oumuamua was. We may possibly have just  

  • witnessed the alien equivalent of the  Titanic zipping past our solar system,  

  • with its deployed solar sail still propelling  it on a never ending journey through the galaxy.

  • The alien theory seems out there, but the shape  of Oumuamua itself does lend it some credibility.  

  • It just so happens that Oumuamua is not only  an extremely unusual shape for a natural comet  

  • or asteroid- in fact, none like it have  ever been observed- but that its skinny,  

  • elongated body is perfect for traveling through  the cosmos at high speeds. When you're moving at  

  • a fraction the speed of light, as even our own  technology today would allow us to accomplish  

  • on long interstellar voyages, running into a speck  of dust would release energy equivalent to a small  

  • nuclear explosion. The best way to avoid strikes  is thus to create the main body of your ship,  

  • where your inhabitants or equipment  is stored, skinny and very long,  

  • reducing the forward-facing profile of the  ship. You would then protect the ship with  

  • an extremely hard nose cone which would  ablate away as you traveled through space.

  • Other observations however reveal that Oumuamua  may instead have been shaped like a very large,  

  • very flat pancake- which makes the  case for a light sail even stronger.  

  • This shape is certainly well outside the  bounds of nature, though sadly Oumuamua's  

  • tumbling and extreme distance from earth  made it difficult to get accurate data.

  • What's even more curious is that Oumuamua seemed  to pass through the goldilocks zone of the sun-  

  • or the area where liquid water, and thus life, is  possible. At its closest, Oumuamua came within 15  

  • million miles of earth (24million km), or about  63 times the distance from earth to the moon.  

  • In astronomical terms, this is basically  invading the earth's personal space- Mars,  

  • our closest neighbor, is over twice that distance,  33.9 million miles, at its closest to us.

  • As if Oumuamua wasn't strange enough already,  

  • observations show that Oumuamua was likely  'at rest' compared to other stars around us-  

  • its speed kept it in the same relative position to  stars around it. Rather than Oumuamua visiting us,  

  • the solar system itself crashed into it as we  orbit the massive black hole at the center of  

  • our galaxy. This type of celestial  motion is extremely rare in nature,  

  • but once more the alien object theory fills  in some holes that traditional theories don't.

  • The solar system orbits around the galaxy in  roughly 230 million years. An alien civilization  

  • using the very same spectroscopy techniques we  use to analyze faraway planets would have been  

  • able to detect unnatural levels of oxygen in our  atmosphere as much as 2.23 billion years ago-  

  • concentrations so high that they could only have  come from life continuously replenishing oxygen in  

  • the atmosphere. Rather than send a probe to us  directly, aliens could have simply left one in  

  • our path for us to run into eventually- especially  if they wanted to gather information about us in a  

  • stealthy manner without giving away obvious signs  of this probe having working technology aboard.  

  • Or, Oumuamua may simply be one of millions of  similar probes scattered across the galaxy,  

  • collecting data automatically as solar systems  run into them and sending it back home.

  • All of this would be an  incredibly lengthy process,  

  • requiring timescales on the millions of yearsyet again, for an advanced enough civilization,  

  • these time scales mean nothing. When your  technology has progressed far enough that  

  • you've survived your first million yearsthe rest are completely inconsequential.

  • Most scientists still believe Oumuamua was  natural, and very publicly oppose any claim  

  • that Oumuamua was alien in origin. However, the  data does indicate that whatever Oumuamua was,  

  • it was without a doubt the most  unusual object humanity has ever seen,  

  • and could have been the first proof of  intelligent life from beyond the earth-  

  • or maybe that's just what the  government is paying us to tell you.

  • Just kidding... though that is what we would  say if we were secretly run by the government,  

  • isn't it?
