10 SURPRISING THINGS SPOTTED WITH SATELLITES

Satellites have become integral to our daily lives—such things as telephone, television, internet, weather forecasts, and GPS tracking just to name a few.  The Hubble telescope allows us to see billions of light years into the vastness of space.  And we can't disregard things long forgotten and/or overlooked.

Phytoplankton Blooms

It's kind of bizarre to think that some of the smallest living things on Earth can make a display that you can see from space. In August of 2012, NASA's Aqua satellite captured some remarkable images of a massive phytoplankton bloom surrounding Russia's Novaya Zemla island. These particular plankton contain plates of a calcium-containing mineral that give them a bright blue color, and when they gather in massive numbers they make an incredible visual image. Temperature and salinity conditions have to be absolutely right to trigger this phenomenon, so capturing it this clearly is pretty amazing.

Hundreds Of Sunken Ships

Much of the ocean is resistant to satellite photography because we don't have cameras powerful enough to penetrate those depths from space. However, there are still amazing things to be seen in the shallows, such as the ghost fleet of Mallows Bay. At the start of World War I, the United States needed to quickly build transport vessels. In April of 1917, 1000 ships were ordered to be built. By the end of the war, the boats had become obsolete and eventually they were sunk to the bottom of the Potomac River at Mallows Bay. From space, the ship graveyard is a striking and amazing sight.

A Marijuana Farm

If you're doing something illegal, it used to be sufficient to put up a fence and keep prying eyes out. But when the eyes are in the sky, things change. Spotting marijuana growths from small planes has been common practice for quite a while. But the owners of a massive marijuana growing operation in Switzerland found that out the hard way in 2010 when Google Earth satellite images revealed their pot fields. Police in Zurich discovered the two-acre field by chance while looking up the address of area farmers, and quickly moved in for the bust. Sixteen people were arrested and over a ton of marijuana was impounded.

Kazakh Geoglyphs

The people of the ancient world did some things that still confound us today. One of the most perplexing is the practice of creating geoglyphs—massive drawings in the earth that are too large to be comprehended from the ground, but show up clear as day from high above. The Nazca lines of southern Peru are the most famous. In 2014 archaeologists happened across a completely new set of geoglyphs in Kazakhstan. The drawings, which depict a number of different geometric shapes, have yet to be explained.

A Hidden Rainforest

It's well-known that the truly wild areas of the planet are dying at a rapid rate, but satellite imagery can often reveal hidden oases that mankind hasn't managed to ruin…yet. That happened in 2005, when scientists at the Royal Botanic Gardens were going over Google Earth images from Mozambique. At the top of Mount Mabu, isolated by steep slopes, was one of the largest untouched rainforests that scientists had ever seen. Villagers had used the site to hide from the civil war that rocked the nation, but aside from that it was on no map and not recognized by the government. Three years later, an expedition found previously undiscovered plants and animals there.

Lost Egyptian Pyramids

One of the most frustrating parts of the archaeologist's craft is having to guess about ancient civilizations buried beneath the surface. Egypt, with its constantly-shifting sands, is especially tough. Thankfully, satellites equipped with infrared cameras have changed the game completely. In a 2011 survey of the country, heat-sensing photography was used to reveal the shapes of seventeen lost pyramids, as well as thousands of other buildings buried beneath the desert.

A Methane Hotspot

Satellites don't just take photos of things we can see with the naked eye. Their advanced sensors allow them to record wavelengths we can't perceive. That's how we found an enormous packet of the greenhouse gas methane hovering over the American southwest. The Four Corners area, where Arizona, New Mexico, Colorado and Utah meet, is a hotbed of natural gas extraction. Scientists believe that the methane was released as a side effect of that industry, and claim that it's equivalent to the entire greenhouse gas output of Sweden.

A Meteor Crater

One of the coolest things about satellite surveillance is that it allows us to see things that would be virtually invisible from the ground. Case in point: the crater from one of Earth's most recent meteor impacts, a scant 5,000 years ago. Measuring just 150 feet wide, this tiny hole in Egypt was first noticed in 2008. But it wasn't until a team analyzed Google Earth images in 2010 that they realized what makes it unusual. The site is what's known as a "rayed crater," featuring lines of lighter-colored rock emanating from the impact area. These craters are common on the Moon but typically eradicated by erosion on Earth, so it's an advantage to science to find a new one.

A New Species Of Hominid

One of the most fascinating discoveries in the history of paleontology—a completely new hominid species that fills in information about the evolution of Homo sapiens. In 2007, South African professor Lee Berger was using Google Earth to examine caves around the so-called "Cradle of Humanity" area of South Africa when he started to notice a pattern. Following it out, he marked 500 other sites that he thought had the potential to produce fossils. The next year, he started to explore them on foot, and one gave up an incredible find: the first bones of Australopithecus sediba, a species that some believe might be the missing link between man and ape.

A Mars Lander

Let's look away from Earth and cast our attention to our nearest planetary neighbor for a look at a mission gone wrong. In 2003, the European Space Agency launched a mission to Mars that involved landing an unmanned craft called the Beagle 2 to take samples and return data. Unfortunately, after launch the ESA lost contact with the Beagle and it vanished into space. A dozen years later, NASA staff operating the Mars Reconnaissance Orbiter's cameras spotted an anomaly on the planet's surface. Upon investigation, they realized they had found the long-missing Beagle 2. The craft's solar panels had failed to open, resulting in mission failure, but it's been sitting on Mars this whole time.

10 Of History's Overlooked Mysteries

History is filled with mysteries, some small scale like the origins of a book and others on a very large scale such as the disappearance of an entire civilization.

I recently came across a list of 10 historical mysteries that don't seem to get too much attention.

The Tarim Mummies

An archaeological excavation beneath the Tarim Basin in western China unearthed more than 100 mummified corpses dating back more than 2000 years.  Even though dug up in China, when a college professor viewed the mummies in a museum, he was shocked to discover they had blonde hair and long noses.  In 1993 he returned to the museum to collect DNA samples from the mummies.  Tests validated his belief, showing that the bodies were of European genetic stock.  Ancient Chinese texts from as early as the first millennium BC mention groups of Caucasian people living in the far east, but there is no mention on any living in the Tarim Basin.

The Voynich Manuscript

This is quite possibly the most unreadable book in the world.  The 500-year-old, 240 page manuscript was discovered in 1912 at a library in Rome.  It contains illustrations and writing in an unknown language.  The best cryptographers have been unable to decipher the text, but statistical analysis of the writing shows that it does seem to follow the basic structure and laws of a working language.

Who Was Robin Hood?

The possible real-life existence of a bandit living in the forest who stole from the rich and gave to the poor is more plausible than the legendary King Arthur and a magical sword named Excalibur.  The historical hunt for the real Robin Hood has discovered several candidates including Robert Hod, a fugitive in Yorkshire who went by Hobbehod as well as Robert Hood of Wakefield.  The name Robin Hood eventually became synonymous with being an outlaw.  His identity would later become even murkier as various authors wove more characters into the tale such as Prince John and Richard the Lionhearted.

The Carnac Stones

As with the construction of Stonehenge, it was a backbreaking task for the people responsible for the Carnac Stones.  On the coast of Brittany, in northwestern France, there are over 3000 megalithic standing stones arranged in exacting lines and spread out over 12 kilometers (7.2 miles).  The local myth explains them as a Roman legion on the march when the wizard Merlin turned them to stone.  The identity of the Neolithic people who build them is unknown.

The Bog Bodies

Hundreds of these ancient bodies have been discovered buried around the northern wetlands of Europe.  Researchers who inspected them have found tell-tale signs of torture and medieval foul play.  These clues have led some to suspect that the dead were victims of ritual sacrifice.  [I recall reading about an incident in England, I think in the 1800s, where a body was found in a bog and it was so well preserved that the locals believed it to be a recent murder which resulted in a police investigation.]

Disappearance Of The Indus Valley Civilization

The ancient Indus Valley people were India's oldest known civilization.  Their bronze-age culture stretched from western India to Afghanistan with a population of over 5 million.  Their abrupt decline rivaled that of the Mayans.  Excavations in 1922 uncovered a culture that maintained a sophisticated sewage drainage system and immaculate bathrooms, but found no evidence of armies, slaves, social conflicts, or other vices prevalent in ancient societies.

The Lost Roman Legion

After an underachieving Roman army led by General Crassus was defeated by Persia, legend says that a small band of POWs wandered through the desert and were captured by the Han military.  An Oxford historian who compared ancient records claimed that the lost Roman legion founded a small town near the Gobi Desert named Liqian, which is Chinese for Rome.  DNA tests are being conducted to hopefully explain some of the residents' green eyes and blond hair. [Which leads one to wonder if there is a connection with the Tarim Mummies.]

Fall Of The Minoans

The fall of the Minoan Empire has proven just as puzzling as the collapse of the Roman Empire.  Approximately 3,500 years ago, life on Crete was disrupted by a huge volcanic eruption on the neighbor island of Thera.  Ancient clay tablets show that the Minoan Empire continued for another 50 years.  Theories about their demise include a blanket of ash devastating their crops and another one says their weakened society was left vulnerable to an eventual Greek takeover.

Lost City Of Helike

The Greek writer Pausanias wrote about a great earthquake that destroyed the city of Helike followed by a tsunami that swept away what remained.  The once flourishing city had been a worship center devoted to Poseidon.  No trace of this legendary society existed outside of ancient Greek texts until 1861 when a bronze coin was found showing the head of Poseidon.  In 2001, the ruins of Helike were located beneath coastal mud and gravel.  Work is currently under way to unearth what some consider the real Atlantis.

Rongorongo

Rongorongo is an indecipherable hieroglyphic writing used by the early inhabitants of Easter Island, often referred to as the other Easter Island mystery.  Rongorongo appeared mysteriously in the 1700s, at a time when no other neighboring oceanic people had any type of written language.  The language was lost along with the best hopes of deciphering it when early European colonizers banned it because of its pagan roots.

Here is a list of 20 common errors. Some are spelling/using wrong spelling of word with same pronunciation, some are different pronunciations of words spelled the same way, and others relate to literally using the wrong words in popular phrases.

1)  It didn't phase me, should be: It didn't faze me.

2)  For all intensive purposes, should be: For all intents and purposes.

3)  He has another thing coming, should be: He has another think coming.

4)  Escape goat, should be: Scape goat.

5)  One in the same, should be: One and the same.

6)  Given free reign, should be: Given free rein.

7)  Low and behold, should be: Lo and behold.

8)  Case and point, should be: Case in point.

9)  Peak your interest, should be: Pique your interest.

10)  Hunger pains, should be: Hunger pangs.

11)  Suppose to, should be: Supposed to.

12)  Should of, should be: Should have.

13)  Nipped that problem in the butt, should be:  Nipped that problem in the bud.

14)  Mute point, should be: Moot point.

The English Language—part 1 of 2

The English language (or at least the American branch of the language) is often confusing even to those who were born here.  I can't imagine trying to learn it as a second language.  Where other languages seem to have set rules, English has rules that are filled with exceptions and sometimes even those exceptions have exceptions.

A good example is the spelling rule for the order of i and e within a word. i before e is the rule. Except after c (exception to rule), or when sounded as a, as in weigh (exception to the exception).

We'll begin with a box and the plural is boxes, but the plural of ox is oxen, not oxes.

One fowl is a goose, but two are called geese, yet the plural of moose should never be meese.

You may find a lone mouse or a nest full of mice, yet the plural of house is houses, not hice.

If the plural of man is always called men, why shouldn't the plural of pan be called pen?

If I spoke of my foot and show you my feet, and I give you a boot, should a pair be called beet?

If one is a tooth and a whole set are teeth, why shouldn't the plural of booth be called beeth?

One may be that and three would be those, yet hat in the plural would never be hose. And the plural of cat is cats, not cose.

We speak of a brother and also of brethren, but though we say mother, we never say methren.

The masculine pronouns are he, his and him, but imagine the feminine as she, shis and shim.

Some reasons to be grateful if you grew up speaking English rather than learning it as a second (or even third) language. Imagine needing to figure out the differences in pronunciation and meaning of these identically spelled words:

1)         The bandage was wound around the wound.

2)         The farm was used to produce produce.

3)         The dump was so full that it had to refuse more refuse.

4)         We must polish the Polish furniture.

5)         He could lead if he would get the lead out.

6)         The soldier decided to desert his dessert in the desert.

7)         Since there is no time like the present, he thought it was time to present the present.

8)         At the army base, a bass was painted on the head of the bass drum.

9)         When shot at, the dove dove into the bushes.

10)       I did not object to the object.

11)       The insurance was invalid for the invalid.

12)       There was a row among the oarsmen about how to row.

13)       They were too close to the door to close it.

14)       The buck does funny things when the does are present.

15)       The seamstress and the sewer fell down into a sewer line.

16)       To help with planting, the farmer taught his sow to sow.

17)       The wind was too strong to wind the sail.

18)       After a number of Novocain injections, my jaw got number.

19)       Upon seeing the tear in the painting I shed a tear.

20)       I had to subject the subject to a series of tests.

21)       How can I intimate this to my most intimate friend?

22)       I spent last evening evening out a pile of dirt.

How many of you had to go back and read any of those 22 examples a second time to get it right? I know I had to look at it a second time.  :)

Let's face it—English is a crazy language.  There is no egg in eggplant nor ham in hamburger; neither apple nor pine in pineapple.  English muffins weren't invented in England.

We take English for granted. But if we explore its paradoxes, we find that quicksand can work slowly, boxing rings are square and a guinea pig is neither from Guinea nor is it a pig.  And why is it that writers write but fingers don't fing, grocers don't groce and hammers don't ham?

Doesn't it seem crazy that you can make amends but not just one amend?

If you have a bunch of odds and ends and get rid of all but one of them, what do you call it, an odd or an end?

If teachers taught, why didn't preachers praught?

If a vegetarian eats vegetables, what does a humanitarian eat?

In what language do people recite at a play and play at a recital?  Ship by truck and send cargo by ship?  Have noses that run and feet that smell?  How can a slim chance and a fat chance be the same, while a wise man and a wise guy are opposites?

You have to marvel at the unique lunacy of a language in which your house can burn up as it burns down, in which you fill in a form by filling it out, and in which an alarm goes off by going on.

If dad is pop, how come mom isn't mop?

Are you totally confused yet?  Check back next week when I continue with the eccentricities of the English language in part 2.
