“What have they done to the earth? What have they done to our fair sister? Ravaged and plundered and ripped her and bit her Stuck her with knives in the side of the dawn And tied her with fences and dragged her down” by The Doors from When the Music’s Over
Earth is the third planet from the sun and in reality it is the only place in our solar system that we can easily call home. Presently, this planet supports a human population of just about 7 billion people….That’s a lot of people……..Still, it remains to be seen if our quality of life can be sustained with this many people on board.
Only after putting to good use one of the great technological developments of the 16th and 17th centuries, was this stargazer able to achieve a greater understanding of the cosmos of which our planet is just a very small part.
The moon displays Synchronous rotation, meaning it undergoes one rotation for each orbit around the earth. The result is that from planet earth, we always see the same side of the moon. This scientific explanation may explain how over time viewers from this planet have attributed human facial characteristics to the “face” of the moon.
The day after Thanksgiving, the internet was all a buzz with news of the comet’s survival, as it passed around the sun on Thanksgiving Day. This is good news for comet watchers and stargazers everywhere and as a result I could not let the day pass without throwing in my two cents worth. Even though ISON’s resurrection may only be a temporary reprieve from death in outer space, the situation has definitely given us comet watchers something to talk about.
Comets and Cats
On Turkey Day, the official skywatchers were calling Comet ISON D.O.A. Then one day later, they were using the cat analogy to salvage their scientific opinion. Most likely this descrepency was not so much due to incompetence, but rather, it may be related to the much improved view that spacecraft such as the Hubble and SOHO can now provide. Never before has modern man received such a superb picture of a comet as it sped across the other side the sun. Nonetheless, it is a very humorous situation to hear the experts backpeddle and use the cat analogy as a defense, even though the premise that comets like cats are unpredictable….has been circulating around the blogosphere for several weeks…..ever since ISON underwent a sudden brightening in mid-November. Also, a corollary has developed; comets like cats, can have nine lies.
The Pros Get It Wrong, Then Right
Now than a new week and a new month has started, it looks like ISON was a doomed comet….that like Icarus….it flew too close to the sun and died. Still, there is a trail of dust (that used to be ISON) moving away from the sun, but it is way too small to be observed by the human eye or even small telescopic devices. Chances that this mass will revive itself into a visible comet are close to zero. Nonetheless, it’s been a fun ride with the general public now being more aware of those faraway visitors from the outer reaches of our solar system. And scientists have gained a little better understanding as to what happens when a comet swings around the sun.
More often than not successful writers, tend to make mostly practical suggestions to newbie writers. Commonly these witticisms contain such mundane advice as don’t use too many adverbs or leave out such over-used words as very, far out or nowadays. Fortunately, every now and then, a lucky writer sneaks in a tidbit of literary comment that transcends these basic grammatical axioms. For example, Stephen King’s classic line, “kill your darlings” has been most likely encountered by just about every practitioner of the English language on at least several occasions.
Following are some of my favorite comments by writers. You have probably heard of most of these guys and gals , but you may not be aware of their cherished little snippets of words. Hopefully, at least a few of these timely lines of wisdom will sink into your brain and create a microburst of energy within your gray matter.
Start as close to the end as possible. by Kurt Vonnegut
Employ an unreliable narrator, preferably one who doesn’t know he is insane and has no recollection of such events as digging into a grave to rip out the teeth of his recently departed lover. by Edgar Allan Poe (note: this comment has been falsely attributed to Edgar Allan Poe, but still ranks as good advice)
Let the audience add up two plus two. They’ll love you forever. by Ernst Lubitsch, screenwriter
Grab ‘em by the throat and never let ‘em go. by Billy Wilder, screenwriter
It is always prudent to remember that one is not Tolstoy or Dickens. by Tracy Kidder and Richard Todd
Never use a metaphor, simile, or other figure of speech which you are used to seeing in print. by George Orwell
Try never get drunk outside yr own house by Jack Kerouac
Remember there is no such thing as nonsense. By Andrew Motion
Every one’s probably heard of this Elmore Leornard quote, but I’ll include it anyway….Try to leave out the part that readers tend to skip.
And last but not least! Ignore all proferred rules and create your own, suitable for what you want to say. by Michael Moorcock
I hope you like the above infrared image of the Andromeda Galaxy. The picture was made from the Herschel, the European Space Agency’s equivalent of our own Hubble satellite. The Herschel was put into orbit in 2009 and features very sophisticated infrared technology.
The Rediscovery of an Extraordinary Century Old Astronomical Event
Recently, a great astronomical event that occurred almost a hundred years ago to the day that the Russian meteors struck, has been making the rounds of the scientific press. Spurred on by a painting made by an amateur astronomer and art teacher in Toronto, named Gustav Hahn, the Royal Astronomical Society of Canada has recently published an article about the spectacular meteor shower that lit up the skies from western Canada to Bermuda and even Brazil.
This spectacular display of fireballs took place over a 24 hour period with the most numerous sightings occurring in eastern Canada. On February 9th 2013, NASA prophetically described the 100-year old event in this way: “Although nothing quite like the Great Meteor Procession of 1913 has been reported since, numerous bright fireballs — themselves pretty spectacular — have since been recorded, some even on video”.
The Reconstructed Image
The above image is a digital scan of the original picture, which was a halftone, hand-painted image that is now part of the University of Toronto archives.
Strangely enough, the NASA story appeared on its Astronomy Picture of the Day site just six days before the meteor exploded above the Ural Mountains of Russia, causing a spectacular view that was widely recorded on video and rapidly disseminated around the world. All of this just goes to prove that sometimes truth can be stranger than fiction.
Copernicus was a Polish astronomer, who revolutionized the study of astronomy, when he theorized that the sun, and not the earth, was the center of our solar system. If Nicolaus were alive today he would be 540 years old. Copernicus’ observations were quite astounding for his day and age, even though they were not published until just a few months before he died in 1543.
The Copernicus Revolution
Copernicus first devised his revolutionary ideas in the 30 to 40 years before he died. Today, it is widely believed that the Polish scientist delayed publishing his heliocentric theory for so long to avoid undergoing the harsh criticism and ridicule that his ideas might precipitate. Strangely enough, his belief in a sun-centered solar system met with little opposition in the first few years following his death.
Galileo Defends Copernicus
This situation soon changed and so for at least a hundred years, Copernicus was made the scapegoat of scientific theory, especially by the church in Rome. However, it was Galileo that took the brunt of the criticism some 90 years later, when he supported Copernicus’ theory. For this, Galileo had to face charges of heresy and eventually recanted on the idea that the earth orbited around the sun.
Finally, in 1835, some 300 years after Copernicus first considered the possibility that the earth revolved around the sun, did the Roman church finally drop their censoring of Copernicus and his revolutionary ideas.
Thanks to the popularity of dashboard cams the internet is abuzz with images and video footage of the meteor(s) that exploded high in the atmosphere near the city of Chelyabinsk, which is located in the Ural Mountains of Russia. According to news reports about a 1,000 people were treated for injuries, mostly from flying glass. Fortunately, no one was killed and none of the injuries were life-threatening. The meteor strike occurred just hours before asteroid da14 passed close to the earth’s surface.
Not everybody believed that the meteor (or meteors) that exploded in Russia were unrelated to the asteroid flyby. For there appeared to be a small cadre of scientists that believed the meteors exploding above Russia were in some way related to the large asteroid that passed by the earth much later in the same day. On CBS, Michio Kaku, a physics professor at the City University of New York, stated that asteroids often occur in swarms or “showers” and so the meteors that passed over Russia may have some connection to the larger asteroid.
Other scientists who share similar views include Tatiana Bordovitsina, an astronomy professor at Tomsk State University in western Siberia, Curtin University asteroid expert Phil Bland of Australia and Professor Ian Crawford of Birkbeck University, who said; “if meteorites were traveling with the asteroid, they would be several hours ahead of it.”
I think that this difference in viewpoints among scientists is fascinating and that ultimately the minority view that the two events are related will prevail. History is just full of too many instances where the majority scientific opinion has been proven more, for me to think otherwise. No matter how this story turns stay in touch for the debate could be very interesting and entertaining.
This asteroid will pass about 17,000 miles from the surface of the earth. At it nearest point it will be closer than the moon and will travel inside the orbit of some satellites. When it does so the space rock will be nearest the South Pacific nation of Sumatra. This asteroid is estimated to be about 150 feet in diameter, which is approximately the same size as the one that hit the Siberian region of Russia in 1908. No ill effects are expected from tomorrow’s flyby.
Asteroid 2012 da14 Returns In 2020
This very same asteroid has an elliptical orbit around the sun and so it will pass by the earth again in another seven years, but it is not expected to hit the earth at this time, either. If an asteroid of this size were to strike the earth, it is estimated that the damage would be similar to the Tunguska Event of 1908 that has already been mentioned above.
Thanks to the internet and modern astronomical observing technology this close passby can be viewed via several different webcasts. These include our very own NASA, along with the Slooh Space Camera, Virtual Telescope Project (Italy) and Bareket Observatory (Israel). The NASA link gives amateur astronomers a chance to track the fast-moving object with a good pair of binoculars or a small telescope. The asteroid will first appear in the southern hemisphere near the Southern Cross and this point it will shine at its brightest.
Eventually, the space object will be visible in the Northern Hemisphere between the Big and Little Dippers, but by this time the high speed traveler will be much dimmer.
On Friday February 15, 2013 an asteroid, half the size of a football field is due to pass about 17, 000 miles from the surface of earth. In astronomical terms that is a “near miss”, but including to all sources, including NASA, no unusual side effects are expected from the extra-terrestrial object, which has been officially named asteroid 2012 DA14.
Something Strange Going On Here
The strange thing going on here is not the so much the close passage of the asteroid, but rather NASA’s PR effort in explaining the science behind what will happen on February 15. One of those unique events is a teleconference tomorrow on Feb. 7th explaining what can be learned from the approach of this asteroid. Also of note is a second animated video that was put together by the NASA Jet Propulsion laboratory, just yesterday. Again NASA is using visual images to downplay the presence of DA14, but in reality, these graphic depictions may be actually having the opposite effect. Stay tuned this may get interesting.
