The Perzog of Mayhem, Or Not


The gringa sees that the conspiracy theorists are at it again and now they are dragging our wonderful little Moon into their tales of mayhem and destruction. So, dear readers, mark your calendars for November 14. It will either be the greatest Moon-viewing experience of your life or the moment you decide to run for your lives and head for the hills.

Conspiracy theorist gong clanging should reach epic decibel levels the closer we get to what scientists commonly call a “supermoon” event. Conspiracy theorists are making sure their innertubes are patched and lifejackets are in order as they are expecting horrific tidal waves and earth-splitting earthquakes. The gringa says, “Are you guys out of your minds or is there some real science to back up your fears?” I mean, living near the Gulf of Mexico the gringa is well-stocked with innertubes and lifejackets but considering the season, they have been relegated to the bottom storage tub with boxes of Halloween, Thanksgiving and Christmas decorations stacked on top in the most convenient order of when I will need them. I would much rather not go to the trouble of rearranging my convenient storage closet system unless the prospect of danger and possible death is real.

Gringa question number one: What the heck is a supermoon? It is technically called a perigee-syzygy. Perigee means: the point in the moon’s orbit when it is nearest to the earth. Syzygy means: when two connected things line up in perfect opposition. The gringa is torn whether to refer to the super-cool term “supermoon” or to come up with my own version of the scientific moniker such as “perzog”. I’m sticking with perzog cuz that’s how I roll. The term supermoon was coined in 1979 by astronomer Richard Nolle. The gringa is the first, however, to use perzog.

So, back to the question of what a perzog is. Every now and then the time is right for a full moon to occur at the exact time it reaches its closest approach to Earth. Remember, orbits are not perfect circles but, rather, elliptical, or egg-shaped or oval. At some point a planetary object will be closer to its neighbor than at other times. The last time perzog happened on the scale expected in November was in 1948. It won’t happen again until 2034. Astronomers have our current perzog showing up next month.

Since worldwide destruction didn’t happen in 1948, the gringa feels pretty confident we should all be just fine. But, just to be on the safe side, I did a little checking on any reports of weather related catastrophes immediately following the perzog of January 26, 1948, paying particular attention to coastal cities and regions.

Seeing as how the 5th Winter Olympic games opened in Switzerland without a hiccup on January 30, 1948 and the 36th annual Men & Women’s Australian Championships in tennis went off without a hitch, the gringa’s convinced that the perzog of 1948 was no big deal, other than being able to view a spectacular Moon.

If there was any imminent disaster it was of political consequence and not weather related. Four days after the 1948 perzog, Mahatma Gandhi was assassinated. Now, the gringa is more likely to believe that mess and mayhem would come from human created disasters rather than massive tidal waves if the Moon is involved.

Is there any increased emergency room activity during full moon events or is this simply an urban legend? The human body is 75% water. If the Moon is powerful enough to push and pull the waters of the ocean, might a similar affect agitate the heck out of a human who is really nothing more than a bag of water? The most interesting medical tidbit to the gringa is that studies produced in 2004 conclude that there is no correlation to the full moon and seizures. The gringa has no excuse for bad behavior on a monthly basis. Despite anecdotal affirmations by ER doctors and nurses that full moons mean a busy night, the data simply doesn’t support their beliefs.

As the perzog shines 30% brighter than ever (at least since 1948), reaching its full glory around midnight between November 13 & 14, coastal dwelling conspiracy theorists will be strapping themselves into their rescue rafts and those living near fault lines will be donning their helmets and hunkering down in doorways awaiting catastrophic earthquakes. They expect tidal forces to reach a zenith that will put an extreme strain on low and high tides worldwide, possibly causing deadly tsunamis. As the Earth’s oceans are trapped in a massive tug of war between the gravitational pulls of the Earth and the Moon, conspiracy theorists propose that the Earth’s crust could very well snap at the strain. California could be lopped off at the San Andreas fault-line with its westernmost extremity falling into the Pacific. Right?

Conspiracy theorists point to the lesser supermoon event of March 19, 2011 as the cause for a Japanese earthquake, resulting tsunami and 5 ships that ran aground in the Solent strait between the U.K.’s mainland and the Isle of Wight. Interestingly enough, the gringa did find two British news reports attributing the groundings to lower than normal water conditions due to the lunar event’s affect on tidal conditions. Maybe there could be some truth to this after all. The British Coastguard, after all, expected extremely low tide conditions because of the lesser supermoon. They were courageous enough to admit that they fell down on the job of managing shipping lane traffic on a new temporary schedule that would account for a change in expected tidal conditions.

But what about the Japanese earthquake and tsunami? Astronomy experts said that it was just silly to blame those terrible events on the Moon. Seeing as how those tragedies happened a week earlier than the lunar event, the perzog of 2011 had nothing to do with the preceding disasters in Japan. The tsunami was caused not by lunar activity but by the largest fault slip ever recorded in modern history.

Clay was to blame, not the moon. The Japanese tectonic plates are lined with clay. The plates are always moving. As they move small portions of clay smear along the area of movement. Natural ground water seepage will moisten the clay. The event of Japan’s massive earthquake was a recipe of water and clay and timing. The plates slipped an historic 5 feet, a massive distance for a tectonic plate. This was the trigger for the tsunami.

So, after a close look at real science and statistics, the gringa is going to enjoy the pleasure of an amazing Moon. While conspiracy theorists miss out on all the fun, cowering in fear, the gringa will be moon-gazing without a backache from rearranging the storage closet or tell-tale distractions wondering if an axe murderer may attack me on my front stoop at midnight, inspired by the super-full-supermoon. I hope my dear readers will enjoy the coming perzog as well. If you do, just imagine, we will all be doing the same thing at the same time if we happen to be in the same time zone! Cool.

Stars Are Cool. No, Really, They Are


When the gringa’s dear readers think of a star, what do you think of? The Sun? Polaris? Alpha Centauri?  And what do you think would happen if you reached out to touch the Sun? You’d probably get vaporized, right? Well, depending on the star, not necessarily. In fact, if you touched the right star it might be a sensation more like when you roll over in bed and find the cool spot.

Brown dwarfs are cold stars. There are 14 that NASA believes are cool enough to touch. Cool! They are also the oldest stars in the Universe. I guess stars are kind of like people. Old folks with poor circulation are generally cold all the time. Stars get old and cold, too. Out of all the old, cold, brown dwarf stars in the Universe, it’s the Y-dwarfs that are even cooler than the average human’s body temperature. Y, you may ask. Well, the gringa will tell you why the Y is the way that it is.

Not only are they old but they are failures. Poor Y-dwarfs. They must have very low self-esteem. Perhaps that is why they don’t shine as brightly as other stars. They have grown old and are failures as stars. The gringa feels very sorry for the poor, little things.

Because their cores are not very dense they can’t fuse loads of atoms within. That means they don’t burn as hot and brightly as other stars. The gringa finds it very amusing that the denser a star is the brighter it is. It doesn’t seem to work that way in humans.

If Y-dwarfs are such failures at being stars, the gringa wonders if they should be considered stars at all. Do we have a Pluto prospect in the future? Just as Pluto got demoted from planet to dwarf planet, Y-dwarf stars may very well face the possibility of being re-classified. In the future scientists may decide they don’t meet all the guidelines of being a star. The gringa thinks this is a wonderful possibility for Y-dwarfs. Whereas poor Pluto suffered a demotion, the Y-dwarf could get better news. They could go from being failures as stars to being over-achievers for whatever it is they may become!

However, it may take astronomers quite some time to collect enough data in their studies. Their failure to shine bright like a diamond in the sky means it is difficult to view and study them. It’s practically impossible to study them at all with a telescope dependent on visible light. To take productive peeks at Y-dwarfs NASA had to construct an infrared telescope and mount it to an orbiting satellite. And that is why the Universe is wiser thanks to these cold, little star failures, because of Wide-field Infrared Survey Explore (WISE) that studies them in the heavens.

Sun Worship


Earlier this month celestial lovers throughout south and central Africa got to enjoy a spectacular solar eclipse that produced a ring of fire as the Moon transversed across the pathway of the Sun. The peculiar occasions when the Earth, Moon and Sun all line up together doesn’t happen too often. Such a rare event has historically been linked with all sorts of predictions and paranormal expectations.

The funniest recording of a solar eclipse is, perhaps, also the earliest record. Occuring in October of the 2137 B.C., two royal astronomers, Ho and Hi, offended the fourth Emperor of China’s Hsia Dynasty,  Chung-K’ang. The eclipse was an unexpected event. The poor astronomers were unprepared to perform the customary rituals that should have taken place. The pair of official stargazers were drunk and failed to launch the traditional arrows and beat out the right rhythm on the gongs and drums so that the Sun could be delivered from the mythical beast that was attempting to devour it.

Convinced that chaos would soon consume the empire, the astronomers were summarily executed as an appeasement sacrifice for their drunken dereliction of duty.  A public record of their death was translated in 1839 by scholars to reveal an amusing verse indicating that, although brutal in enforcing their expectations, the ancient Chinese did have a sense of humor:

“Here lie the bodies of Ho and Hi,

Whose fate though sad was visible –

Being hanged because they could not spy

Th’ eclipse which was invisible.”

In November of the year 569 an eclipse was recorded before the birth of the Prophet Mohammad in 570. There are many religious historians who link this eclipse as the moment of Mohammad’s conception. Interestingly enough Mohammed’s son Ibrahim died at the age of two-years-old during the occurrence of a solar eclipse. Mohammed wrote of this event as a sign sent from his God, Allah, of personal condolences. Muslims today still consider eclipses significant religious events. When the recent eclipse occurred mosques throughout Africa had special calls to prayer for safety and deliverance from harm.

Perhaps the most significant solar eclipse in modern history is the one of May, 1919. Commonly called “Einstein’s Eclipse”, it is considered to be the solar eclipse that changed the universe. For more than 200 years scientists had accepted Isaac Newton’s principle that the space of the Universe was as inflexible as mathematical principles.  Einstein set out to challenge this longheld belief. Einstein believed gravity was curved and flexible, affected by the mass of planetary bodies. He proposed that warping of space allowed planets to remain in their orbital paths, gravity distorted by the mass of a celestial body, the greater the mass, the stronger the force, which would result in more bending of light. This was to become known as Einstein’s Theory of Relativity.

When the 1919 eclipse occurred, British astrophysicist Sir Arthur Stanley Eddington led the charge for an experiment to take advantage of the expected eclipse. Eddington traveled to Principe which is in the Gulf of Guinea off of Africa’s western coastline. A horrible thunderstorm threatened to ruin Eddington’s chances but, fortunately, by afternoon the skies had cleared. Eddington’s celestial photographs and measurements were compared with photos and measurements recorded by Andrew  Crommelin at the Royal Observatory at Greenwich. The findings were announced by Britain’s Royal Society’s Astronomer Royal Sir Frank Watson Dyson. It was announced in London on November 6, 1919 that Newton’s theory had been disproven by Einstein’s new Theory of Relativity.

To make sure that you are ready for the next opportunity to view a solar eclipse, log on to www.timeanddate.com and keep a watch on the countdown clock for eclipses listed under their Sun & Moon tab. It seems we are only about 5 months away from the next big event.  There is a handy search window everyone can use to see if their city or country is going to be in the most fortunate position of being able to see the eclipse.

To view a solar eclipse it is important to wear protective eyewear. A homemade viewbox can also be created called a pinhole camera. All you need is a box with a small hole on one side for light to pass through and project an inverted image of the eclipse on the opposite side.  Below is a video with an example of how to make and use a homemade pinhole camera. One tip: The bigger the box the better the view.

Cannibals & Their Lightning God


Two things the gringa loves most are science and history. When the two collide I believe I am in Paradise.  Add the spice of controversy and there is simply no going back for the gringa. Archaeologists in Greece have made this dream combination come true for the gringa.

Let us travel back 3,000 years to the bleak mountaintop of Mount Lykaion in southern Greece, which some ancient Greeks believed to be the birthplace of Zeus, rather than Crete. This is the revered resting place of an altar featuring a grisly design of sheep bone construction. This is where the religious leaders of Greece hoped to pacify their god of gods, Zeus himself. Offered up are the bloody sacrifices of what one would expect to be sheep or goats, considering what the altar is made of. Think again dear readers.

For those schooled in literature and philosophy, when Greece is mentioned, you hearken back to the days of Plato and Socrates. You believe these sophisticated thinkers of Greece gave birth to civilized society as we know it. As you cruise about town, passing homes with columned porches, you remind yourself that this bit of architecture was passed down from an exceptionally cultured society. Or not. Not when the skeletal remains of a teenage boy near Zeus’ altar indicates that young, human sacrifices were being bled out on top of a table made from sheep bones in efforts to gain favor with a god that might rain down lightning if he got pissed.

But Mount Lykaion is historically linked to Greek athletic festivals, isn’t it? Isn’t it one of the ancient sites with a stadium and hippodrome, all indicators of a culture that appreciated athletic competitions? The gringa wonders, was death the price for losing or, could it have been the price for winning, or, could it have been the “opening ceremony” after which a priest turns around and commands, “Let the games begin!” Who really knows at this time because this is a recent discovery.

And some scholars are not too happy about revelations of human sacrifice as part of ancient Greek religious ceremonies. I mean, after all, Greece way back then liked to call rival foreign nations nasty names like barbarians and cannibals. But, really, who do they think they are fooling? Remember, Socrates asked Adeimantos if he had heard the latest gossip about religious zealouts feasting on the remains of their human sacrifice. Socrates includes a gruesome description of a terrible recipe of mixing the entrails of different victims which, if ingested by some hapless cannibal, transforms them into a wolf. Considering that Adeimantos had already heard the story, it seems that the nasty religious practices going on atop Mount Lykaion were no big secret among the ancient Greeks. It’s just big news to us.

So what kind of science goes into the decision that the remains of this young man belong to a specific era and culture? Scientists have to analyze the composition of the altar itself. Considered an “ash altar”, the gringa’s depiction of it being constructed in the fashion of, say, a dining room table and made completely out of sheep bones is not an altogether clear picture of what scientists are dealing with. Imagine, if you will, that ancient priests led sheep and goats to a sacred place, slit their throat, then burned the remains. Each sacrifice slaughtered and burned atop the ones that went before. Eventually a mound of ash accumulates and becomes a ritual platform. At Mount Lykaion the mound was almost five feet high.

So, the scientists use their handy-dandy equipment to measure remains of bones to see which animal (or human) they belong to. If human, they measure the pelvis to see if it is male or female. Then they need to determine the age of the remains. The first thing that comes to mind is ye aulde carbon dating technique. But there are other methods that can be used on other objects and archaeological sites to determine age:

  • Stratigraphical: The science of geology comes into play with a method that relies on the accumulation of soil to calculate the passage of time. The premise is that the area where people live results in layers of earth becoming deposited. Gives a whole new meaning to the saying that a particular area sure has “built up”.
  • Astronomical Chronology: Astronomers have used their knowledge to study the fluctuations of solar radiation to calculate when ice ages have occurred. The common argument is that 5 have occurred.
  • Dendrochronology: This science was pioneered in 1904 by A.E. Douglass who created the technique of analyzing tree rings to determine not only the age of a tree but to find indicators of drought, disease and hearty growing seasons.

So, if history, science and drama are appealing to someone you know, remind them that there are still exciting discoveries to be made, particularly in Greece. For young people who long for the curiosities that are found in archaeological digs, remind them that not every ancient puzzle has been solved. Along with history, they should also have a strong foundation in STEM studies.  And lucky for me this archaeological site has its own website keeping fascinated individuals like myself up-to-date on their latest discoveries. Because the gringa really wants to know just went on up there.

August Astronomy


Space fans should get their binoculars and telescopes dusted off for August. There will be lots to see with the aid of machine or the trusty naked eye. The gringa will share a cosmic calendar for the month ahead so everyone schedule their dinners and bedtimes accordingly if you want to enjoy some breathtaking galactic events rather than hunker down for digital entertainment indoors.

August 2 – New Moon:  Without the interference of moonlight this is the perfect night to explore other galaxies and nearby star clusters who will be shining in all their glory with no competition from our little satellite.

August 11,12 – Perseids Meteor Shower: At its peak, this little baby (pictured above) has the potential to create up to 60 meteors per hour (gives a whole new meaning to MPH). We can all thank comet Swift-Tuttle for this fantastic light show. Discovered in 1862. it has consistently provided entertainment for Earthlings through July and August. The event will peak on these two days in August. The best time to watch is right after the moon sets around midnight. Or, for those early to bed and early to rise, a pre-dawn show is also prime time for Perseids observation.

August 16 – Mercury:  This is the best time to view Mercury as it reaches it greatest eastern elongation from the Sun. Look for it in the evening sky at the highest point of the horizon or at a low point in the western sky just after sunset.

August 18 – Full Moon:  This is the best time to get a great look at our pockmarked neighbor. Full illumination will occur between 9-10pm  UTC. A bit of full Moon trivia: some Native American tribes call the full Moon a Full Sturgeon Moon because these nights are the best times to catch this type of fish that populates the Great Lakes. Other tribes also called the full Moon the Green Corn Moon or the Grain Moon.

August 27 – Venus & Jupiter:  These two planets are going to join together in close proximity for a spectacular opportunity to see them both. Look for them in the western sky soon after sunset.  They will be shining very brightly and close together.

Ceres, Dawn, Pyramids & Craters


NASA’s spacecraft Dawn has been on a mission to the planet Ceres which is located between the orbits of Mars and Jupiter. Compared to Earth’s diameter of almost 8,000 miles, Ceres seems tiny with a diameter of less than 600 miles. It is so small that despite its official designation as a minor-planet, there are still those who will call it an asteroid or a dwarf planet. To put it in perspective, the entire surface of Ceres is about the same size as India or Argentina. Whatever the moniker, the dear reader gets the point. Still, UFO and ET enthusiasts like to believe that Ceres was once home to an intelligent otherworldly species that liked to build pyramids. The gringa can only say, “Um, not.”

Why is the gringa so sure of herself in raining on their parade? Let’s take a look at some of the geographical and geological characteristics of this teensy-weensy little world:

Craters

First of all, just take an up close and personal look at the pitiful pitted little thing. It has more impact craters than an eight-year-old ginger gringa had freckles. It seems pretty obvious to me that with global environmental disasters happening on a regular basis, it is very unlikely that life would flourish in such a place. Not to mention any surviving life having the opportunity to pursue advancements.

Elements

Ceres, in many ways, is pretty much a clone of our desolate moon, an enormous rock with a lot of ice. With no evidence or traces of ever having vegetation, any ETs most assuredly would have starved to death. Unless, of course, it was a civilization that could survive on the nourishment of clay seasoned with ammonia and a splash of salt and iron.

Environment

It’s highly unlikely that water as we Earthlings know it ever existed on Ceres. Although there is alot of ice, enough even to indicate the possibility of an ocean at one time, it wouldn’t have been a salty brine like we are accustomed to, inhabited with sharks and whales and penguins and such. It most likely would have been a caustic sea of ammonia and sulfuric acid. So, unless those ETs had skin of steel and enjoyed a dip in antifreeze, any recreational activities of a Ceres civilization would have been strictly limited to land-lubbing.

Details, Details, Details

If the gringa has sufficiently convinced you that no one was building pyramids on Ceres way back when, let us move on to the details that are still interesting despite lacking any ET spin.

In the late 1700s Johann Elert Bode suspected a planet existed between Mars and Jupiter. However, the official discovery of Ceres is credited to Giuseppe Piazzi in 1801 who first claimed it was a comet. It was later classified as a planet but then redesignated as an asteroid in the 1850s. It seems scientists still haven’t made up their minds because it can be called any number of names when referred to by different people. The gringa doesn’t so much care. It makes no difference to me. Ceres is just Ceres, a planet named after the Roman goddess of agriculture despite the fact that not a single ear of corn or blade of grass has ever been grown on its surface.

Over thousands of years meteors and comets have slammed into Ceres, creating hundreds of craters. A few of them are distinctly bright, containing either minerals with reflective properties or light reflecting off of ice. It is theorized that underneath the crusty and dusty surface of Ceres is a layer of water and ice that, by volume, is more than the fresh water found on Earth. This has led to scientists entertaining the notion that if living organisms once lived in the sea of Ceres, it is possible that through the many cosmic impacts throughout history some biological material may have been ejected into space and made its way to Earth. So, ETs on Ceres? The gringa thinks not. ETs from Ceres on Earth? It’s possible.

Viewing

Ceres is too dim to be seen with the naked eye except on extremely dark sky conditions. The best way to peek at Ceres is through a pair of binoculars or a telescope. The best time to see Ceres is fast approaching, from August through April. Observers in mid northern latitudes should look toward the low southern sky after nightfall. It is best to view on a night when the Moon is in waning stages. Look toward the Sagittarius constellation and Ceres will arc slowly westward and approach the border of the Capricorn constellation.

If you have a fancy telescope you can enter coordinates and the telescope will do the hard work of locating and tracking for you. But if you only have binoculars, it is still easy enough to locate and track Ceres so don’t be discouraged.   For some help in finding Ceres, online astronomy clubs are a great resource.  The gringa wishes you the greatest success in taking a peek at Ceres!

The Truth About Tabby


UFO and alien conspiracy theory buffs are going to enjoy this post by the gringa, or not. I guess it depends on if you enjoy a healthy dose of conspiracy debunking or truth. You see, dear readers, there has been a bit of hubbub about an interesting space object that is orbiting a nearby star and was detected by the Kepler telescope late last year.

The SETI Institute (Search For Extraterrestrial Intelligence) calls KIC 8462852 “mysterious”. NASA believes the mystery is resolved with the theory that the strange signals are the result of cosmic dust, probably from multiple impacts of a comet swarm, and causes the star’s light to flicker erratically. Vanderbilt University researchers, who affectionately call the star Tabby, debunk theories by those who believe it to be home of aliens who are very, very busy. The astrophysicist contributors to the respectable Astrophysical Journal agree with Vanderbilt’s point of view while at the same time agreeing with theories from other scientists who propose an extraterrestrial origin theory. So, who’s got it right? Who’s got it wrong? Just what the heck is the truth about Tabby?

Who Is Tabby

Tabby is officially designated star KIC 8462852 and shines brighter than our own Sun about 1400 light years from Earth in the Cygnus constellation. It is a subject of study by NASA’s Kepler space telescope which reveals that from time to time it dims about twenty percent in brightness.

SETI’s Conclusion

The cause of the dimming light could possibly be because of material or objects orbiting the star. SETI researchers believe they have evidence to determine that these objects are not planets. SETI considers the possibility that Tabby could be home to a technologically sophisticated society that has constructed a swarm of solar panels that orbit the star which would account for the light fluctuations.

SETI uses its own Allen Telescope Array to study radio signals that originate from that part of outer space. They attest that these radio signals are of artificial origin, calling them “non-natural”. They search for narrow-band signals and broadband that might possibly be produced by a large and powerful spacecraft. They also search for evidence of laser pulses. SETI’s Panamanian partner, Boquete Optical SETI Observatory, performs the laser pulse research.

Research such as this takes a long time so the gringa will have to practice patience for SETI to conclude their studies and publish their final results. They admit that, historically, cases like this usually result in finding a natural cause for the anomalies but they still must investigate the possibility of it originating from extraterrestrial intelligence. That is, after all, their mission.

NASA’s Conclusion

During four years of observation, the Kepler mission recorded strange happenings in 2011 and 2013 when interesting and dramatic light fluctuations occurred. To help determine what happened, NASA also trained the eye of the Spitzer Space Telescope in Tabby’s direction. Kepler observed the visible light. Spitzer could delve deeper into the invisible infrared light signals and patterns. In November of last year Spitzer paid off with a recording of another light fluctuation.

Although NASA’s theory is that clouds of space dust were formed from a swarm of comets that orbit the star in erratic patterns, Spitzer did not discover evidence to support this theory. This caused NASA to switch to a cold comet theory. One lead comet would be followed by a swarm of smaller comets. If this is true, even if the comets were already out of the telescope’s view as they traveled around Tabby, they should still leave behind a detectable infrared signature. However, this was not the case.

Researchers admit that more observations need to be recorded to determine just exactly what is going on. NASA admits that Tabby is strange, indeed. However, they believe that a natural cause is more likely than “little green men”.

Vanderbilt University’s Conclusion

Vanderbilt studies focused on the 100 day period when the most significant light fluctuations occurred. The manner in which they occurred suggested that a large number of “irregularly shaped objects” passed in front of the star causing its light to be blocked temporarily. Working off a report from an astronomer at Louisiana State University who concluded that the star had diminished in brightness by 20 percent over the past century, Vanderbilt finds a natural cause unlikely as an explanation for this. This has become fodder for the theory that a megastructure has been constructed that is absorbing the star’s energy, the solar panel array theory. This is a theory that was reviewed, accepted and published by the Astrophysical Journal.

Vanderbilt, however, did not stop there. They soldiered on. Partnering with amateur German astronomer, Michael Hippke and NASA scientist Daniel Angerhausen, the team began comparing the 20 percent drop in intensity to other stars. They discovered that this is not an unusual phenomenon. In fact, it’s not a star phenomenon at all. It is simply the result of technological changes and advances of human manufactured instrumentation for observance.

The Gringa’s Conclusion

These are all interesting theories but not yet solid answers. So, the gringa will wait and see if, ten or twenty years down the road, we all find out what the actual, final answer is:

  • Comet Swarms

or

  • Extraterrestrial Solar Array

Until then, Tabby will be the most interesting and mysterious star in our night sky.
