Celebrating Genocide – The Real Story of Thanksgiving

Irwin Ozborne, ContributorThanksgiving: Celebrating all that we have, and the genocide it took to get it.Thanksgiving is one of the most paradoxical times of the year. We gather together with friends and family in celebration of all that we are thankful for and express our gratitude, at the same time we are encouraged to eat in excess. But the irony really starts the next day on Black Friday. On Thursday we appreciate all the simple things in life, such as having a meal, a roof over [...]

Explosive Culprit? Russian Fireball’s Origins Found


A photograph of the Annama meteorite fireball over Russia's Kola Peninsula.



Excerpt from space.com

A crackling fireball that exploded over Russia last year appears to share an orbit with a huge asteroid discovered in October 2014, a new study reports.

The Kola fireball was spotted on April 19, 2014, as it lit up the night sky above the Kola Peninsula near the Finnish-Russian border. Its orbit is "disturbingly similar" to the asteroid 2014 UR116, slated to pass by the moon in 2017, the study authors said.
Camera observations by the Finnish Fireball Network, which monitors the sky for meteors and fireballs, and video from eyewitnesses helped scientists recreate the meteoroid's trajectory and hunt down meteorite fragments on the ground. 


Josep Maria Trigo-Rodríguez, a researcher at the Institute of Space Sciences in Barcelona, Spain, led the international team of scientists who analyzed the meteorite's orbit. They calculated the fireball's size and path through Earth's atmosphere by examining its flight and the meteorite's final impact site. A computer model based on these figures was used to estimate the space rock's orbital path. 

The 1,100-pound (500 kilogram) meteorite is an ordinary H5 chondrite, a type of stony meteorite responsible for 31 percent of Earth's impacts. The fragments are called the "Annama meteorite" because the meteorite fell near the Annama River in Russia.

Annama meteorite

The precise detective works suggests the fireball escaped from the innermost region of the asteroid belt, the study researchers reported. The rock has an elliptical orbit that is typical of the Apollo family of near-Earth orbiting asteroids, and it likely came from the same broad source region as the Lost City, Peekskill and Buzzard Coulee meteorites, the researchers said.

The researchers compared the Annama meteorite's orbit with known near-Earth asteroids (there are more than 1,500). Of 12 potential matches, by far the closest match was with the asteroid 2014 UR116, they said.

The findings were published April 7 in the journal Monthly Notices of the Royal Astronomical Society.

The new report does not suggest that asteroid 2014 UR116 flung the Annama meteorite directly at Earth. However, the two bodies could be related. Scientists think that streams of asteroid fragments — such as the remnants of interstellar collisions — can sail on nearly identical orbits. Tidal forces may stretch out these rocky debris patches over time. Asteroids may also fragment from the stress of passing near the planets, the researchers noted.

"The tidal effect on an asteroid, which rapidly rotates under the gravitational field of a planet, can fragment these objects or release large rocks from its surface, which could then become dangerous projectiles at a local scale, such as the one that fell in Chelyabinsk, Russia," Trigo-Rodríguez said in a statement.

Asteroid 2014 UR116, discovered by Russian scientists on Oct. 27, 2014, measures 1,312 feet (400 meters) across, but does not pose an impact danger to Earth, according to NASA.

A Complete Guide to the March 20th Total Solar Eclipse

Excerpt from universetoday.com



The first of two eclipse seasons for the year is upon us this month, and kicks off with the only total solar eclipse for 2015 on Friday, March 20th.

And what a bizarre eclipse it is. Not only does this eclipse begin just 15 hours prior to the March equinox marking the beginning of astronomical spring in the northern hemisphere, but the shadow of totality also beats path through the high Arctic and ends over the North Pole.

Already, umbraphiles — those who chase eclipses — are converging on the two small tracts of terra firma where the umbra of the Moon makes landfall: the Faroe and Svalbard islands. All of Europe, the northern swath of the African continent, north-central Asia and the Middle East will see a partial solar eclipse, and the eclipse will be deeper percentage-wise the farther north you are .
2015 features four eclipses in all: two total lunars and two solars, with one total solar and one partial solar eclipse. Four is the minimum number of eclipses that can occur in a calendar year, and although North America misses out on the solar eclipse action this time ’round, most of the continent gets a front row seat to the two final total lunar eclipses of the ongoing tetrad on April 4th and September 28th.

How rare is a total solar eclipse on the vernal equinox? Well, the last total solar eclipse on the March equinox occurred back in 1662 on March 20th. There was also a hybrid eclipse — an eclipse which was annular along a portion of the track, and total along another — on March 20th, 1681. But you won’t have to wait that long for the next, as another eclipse falls on the northward equinox on March 20th, 2034.

Note that in the 21st century, the March equinox falls on March 20th, and will start occasionally falling on March 19th in 2044. We’re also in that wacky time of year where North America has shifted back to ye ‘ole Daylight Saving (or Summer) Time, while Europe makes the change after the eclipse on March 29th. It really can wreak havoc with those cross-time zone plans, we know…
The March 20th eclipse also occurs only a day after lunar perigee, which falls on March 19th at 19:39 UT. This is also one of the closer lunar perigees for 2015 at 357,583 kilometres distant, though the maximum duration of totality for this eclipse is only 2 minutes and 47 seconds just northeast of the Faroe Islands.

This eclipse is number 61 of 71 in solar saros series 120, which runs from 933 to 2754 AD. It’s also the second to last total in the series, with the final total solar eclipse for the saros cycle occurring one saros later on March 30th, 2033.



What would it look like to sit at the North Pole and watch a total solar eclipse on the first day of Spring? It would be a remarkable sight, as the disk of the Sun skims just above the horizon for the first time since the September 2014 equinox. Does this eclipse occur at sunrise or sunset as seen from the pole? It would be a rare spectacle indeed!

Safety is paramount when observing the Sun and a solar eclipse. Eye protection is mandatory during all partial phases across Europe, northern Asia, North Africa and the Middle East. A proper solar filter mask constructed of Baader safety film is easy to construct, and should fit snugly over the front aperture of a telescope. No. 14 welder’s goggles are also dense enough to look at the Sun, as are safety glasses specifically designed for eclipse viewing. Observing the Sun via projection or by using a pinhole projector is safe and easy to do.

Weather is always the big variable in the days leading up to any eclipse. Unfortunately, March in the North Atlantic typically hosts stormy skies, and the low elevation of the eclipse in the sky may hamper observations as well. From the Faroe Islands, the Sun sits 18 degrees above the horizon during totality, while from the Svalbard Islands it’s even lower at 12 degrees in elevation. Much of Svalbard is also mountainous, making for sunless pockets of terrain that will be masked in shadow on eclipse day. Mean cloud amounts for both locales run in the 70% range, and the Eclipser website hosts a great in-depth climatology discussion for this and every eclipse.

But don’t despair: you only need a clear view of the Sun to witness an eclipse!

Solar activity is also another big variable. Witnesses to the October 23rd, 2014 partial solar eclipse over the U.S. southwest will recall that we had a massive and very photogenic sunspot turned Earthward at the time. The Sun has been remarkably calm as of late, though active sunspot region 2297 is developing nicely. It will have rotated to the solar limb come eclipse day, and we should have a good grasp on what solar activity during the eclipse will look like come early next week.

And speaking of which: could an auroral display be in the cards for those brief few minutes of totality? It’s not out of the question, assuming the Sun cooperates.  Of course, the pearly white corona of the Sun still gives off a considerable amount of light during totality, equal to about half the brightness of a Full Moon. Still, witnessing two of nature’s grandest spectacles — a total solar eclipse and the aurora borealis — simultaneously would be an unforgettable sight, and to our knowledge, has never been documented!

We also put together some simulations of the eclipse as seen from Earth and space:




Note that an area of southern Spain may witness a transit of the International Space Station during the partial phase of the eclipse. This projection is tentative, as the orbit of the ISS evolves over time. Be sure to check CALSky for accurate predictions in the days leading up to the eclipse.

Rare doomed planet with extreme seasons discovered

Excerpt from foxnews.com/science


A rare planet has been discovered, and it doesn’t seem like a stop anyone would want to make on an intergalactic cruise. Found by two research teams independently of each other, Kepler-432b is extreme in its mass, density, and weather. Roughly the same size of Jupiter, the planet is also doomed- in 200 million years it will be consumed by its sun. “Kepler-432b is definitively a rarity among exoplanets around giant stars: it is a close-in gas-giant planet orbiting a star whose radius is 'quickly' increasing,” Davide Gandolfi, from the Landessternwarte Koenigstuhl (part of the Centre for Astronomy of the University of Heidelberg), told FoxNews.com. “The orbit of the planet has a radius of about 45 million kilometers [28 million miles] (as a reference point, the Earth-Sun distance is about 150 million kilometers [93.2 Million miles]), while most of the planets known to orbit giant stars have wider orbits. The stellar radius is already 3 million kilometers [almost 2 million miles] (i.e., about 4 times the Sun radius) and in less than 200 million years it will be large enough for the star to swallow up its planet.”

Gandolfi, a member of one of the research groups who discovered the rare planet, explains that much like Jupiter, Kepler-432b is a gas-giant celestial body composed mostly of hydrogen and helium, and is most likely to have a dense core that accounts for 6 percent or less of the planet’s mass. “The planet has a mass six times that of Jupiter, but is about the same size!” he says. “This means that it is not one of the largest planets yet discovered: it is one of the most massive!” The planet’s orbit brings it extremely close to its host star on some occasions, and very far away at others, which creates extreme seasonal changes. In its year - which lasts 52 Earth days - winters can get a little chilly and summers a bit balmy, to say the least. According to Gandolfi, “The highly eccentric orbit brings Kepler-432b at ‘only’ 24 million kilometers [15 million miles] from its host star, before taking it to about three times as far away. This creates large temperature excursions over the course of the planet year, which is of only 52 Earth days. During the winter season, the temperature on Kepler-432b drops down to 500 degrees Celsius [932 degrees Fahrenheit], whereas in summer it can goes up to nearly 1000 degrees Celsius [1832 degrees Fahrenheit].”

Then again, if you are crazy enough to visit Kepler-432b, you’d better do it fast. As stated before, its host star is set to swallow the planet whole in 200 million years, making the celestial body a rare find. “The paucity of close-in planets around giant stars is likely to be due to the fact that these planets have been already swallowed up by their host stars,” Gandolfi says. “Kepler-432b has been discovered ‘just in time before dinner!” The host star, which is red and possesses 1.35 times the mass of our sun, has partly exhausted the nuclear fuel in its core, and is slowly expanding, eventually growing large enough to swallow Kepler-432b. According to Gandolfi, this is a natural progression for all stars. “Stars first generate nuclear energy in their core via the fusion of Hydrogen into Helium,” he explained. “At this stage, their radii basically do not change much. This is because the outward thermal pressure produced by the nuclear fusion in the core is balanced by the inward pressure of gravitational collapse from the overlying layers. In other words, the nuclear power is the star pillar! Our Sun is currently ‘burning’ hydrogen in its core (please note that I used quotes: ‘burning’ does not mean a chemical reaction- we are talking about nuclear fusion reaction). However, this equilibrium between the two pressures does not last forever. Helium is heavier than hydrogen and tends to sink. The stellar core of the Kepler-432b's host star is currently depleted of hydrogen and it is mainly made of inert helium. The star generates thermal energy in a shell around the core through the nuclear fusion of hydrogen into helium. As a result of this, the star expands and cools down. This is why we call it ‘red giant’- the reddish color comes from the fact that the external layers of the atmosphere of the star are cooling down because they expand.”

Both research teams (the other was from the Max Planck Institute for Astronomy in Heidelberg) used Calar Alto Observatory’s 7.2- foot telescope in Andalucia, Spain. The planet was also studied by Landessternwarte Koenigstuhl researchers using the 8.5-foot Nordic Optical Telescope on La Palma, which is located in Spain’s Canary Islands.

Mysterious plumes in Mars’ atmosphere baffle astronomers




Excerpt from thespacereporter.com

Astronomers are baffled by images of plumes rising from Mars’ atmosphere in images taken by amateur astronomers in March and April 2012.

The plumes were present for about 10 days though their shapes and sizes changed rapidly during that time, from finger-like tendrils to spherical blobs.

Researchers have proposed several possible explanations for the plumes, which are discussed in an article just published in the journal Nature.

Each of the theories being considered poses problems. One theory, for instaqnce, proposes the plumes are caused by the same magnetic influence that causes the aurora borealis, or Northern Lights, on Earth. The movement of electrically charged particles from the Sun, driven by the solar wind towards Earth’s poles, results in these particles colliding with molecules of gas. These collisions produce the strange lights known as aurorae.

In the study, the researchers admit, “Mars aurorae have been observed near where the plume occurs, a region with a large anomaly in the crustal magnetic field that can drive the precipitation of solar wind particles into the atmosphere.”
The problem with this theory is this would only happen if the Sun released an exceptional amount of energetic particles during the time the plumes were seen. Yet the level of solar output in 2012 was nowhere near sufficient to release such a powerful stream of particles, the authors of the paper acknowledge.

They move on to consider another option, namely that the plumes might be clouds high in the Martian atmosphere.

A highly reflective cloud of either water ice, carbon dioxide ice, or dust particles could explain the plumes. But according to computer models, the presence of these clouds “would require exceptional deviations from standard atmospheric circulation models to explain cloud formations at such high altitudes,” explained the paper’s lead author, Agustin Sanchez-Lavega of the Universidad del Pais Vasco in Spain.

The plumes were seen approximately 120 miles (200 km) from Mars’ surface, which is problematic because the highest Martian clouds are seen is 60 miles (100 km) above the planet’s surface. The only way water can condense so far up is if the temperature in that part of Mars’ atmosphere drops 370 degrees Fahrenheit, or 50 degrees Kelvin, below its norm.

Condensation of carbon dioxide would require twice this temperature drop.

A third theory posits the flumes are caused by atmospheric dust. A wind powerful enough to transport dust 111 miles (180 km) above Mars’ surface could occur only around noon, when the Sun’s heat would be strong enough to create such wind currents.

However, the plumes were seen not at noon but in the mornings along the terminator that separates the planet’s day and night sides.
Recently, data from the Hubble Space Telescope was found showing the plumes back in 1997.

Ground-based telescope spots alien ‘Super-Earth’

An artist's conception shows the size of super-Earth 55 Cancri e compared to Earth. A ground-based telescope in Spain was able to identify 55 Cancri e, which suggests that telescopes on the ground help in the search for habitable planets around other stars.


Excerpt from csmonitor.com

A telescope on the Canary Islands has spotted a planet twice the size of Earth as it passed in front of a star, the first time a planet in this category has been detected by a ground-based telescope.

Finding Earthlike planets beyond our solar system has largely been the work of space-based telescopes, but new observations from a remote island suggest that could change.

The Nordic Optical Telescope on La Palma — one of the Canary Islands off the west coast of Africa — observed 55 Cancri e, a planet twice the size of Earth, as it passed in front of its parent star and caused a dip in the star's brightness, according to a new study. This is the first time a planet in this "super-Earth" size category orbiting a sunlike star has been observed by a ground-based telescope using this detection method, the researchers say.

First identified in 2004 by a space-based telescope, 55 Cancri e has a diameter of about 16,000 miles (26,000 kilometers) — about twice that of Earth. The alien world is eight times as massive as Earth, making it a so-called super-Earth, a planet more massive than Earth but significantly smaller than gas giants like Neptune and Uranus. While not habitable, the planet's size and position around a sunlike star make it similar to planets that might support life, researchers say. 

The planet's detection with the Nordic telescope shows that observatories on the ground could use what's called the transit method — watching for dips in the brightness of a star to indicate a planet passing in front of it — to assist space-based telescopes in follow-up studies of super-Earths or Earthlike exoplanets, scientists say.

Nearly 2,000 exoplanets have now been confirmed, and upcoming exoplanet searches promise to expand that catalog. 

"We expect these surveys to find so many nearby terrestrial worlds that space telescopes simply won't be able to follow up on all of them. Future ground-based instrumentation will be key, and this study shows it can be done," Mercedes Lopez-Morales, co-author of the new research and a researcher at the Harvard-Smithsonian Center for Astrophysics (CfA), said in a statement.

Five exoplanets orbit the star 55 Cancri, which is located 40 light-years from Earth and is visible to the naked eye. The closest-orbiting of those five is 55 Cancri e, which completes one lap around the star every 18 hours. When the planet passes between Earth and the parent star, 55 Cancri appears to dim by 1/2000th (or 0.05 percent) for almost 2 hours, researchers said.


Daytime temperatures on 55 Cancri e likely reach higher than 3,100 degrees Fahrenheit (1,700 degrees Celsius) — hot enough to melt metal and much too hot to support life. But scientists involved with the study say this approach could help characterize the atmosphere of more hospitable Earthlike or super-Earth planets.


After its initial detection, 55 Cancri e also became the first super-Earth seen by NASA's Spitzer Space Telescope, using light directly from the planet. Thus, it has now served twice as a litmus test for super-Earth detection methods. 

In addition to the wealth of planets identified by NASA's Kepler Space Telescope, the space agency's Transiting Exoplanet Survey Satellite (TESS) mission, scheduled for launch in 2017, is expected to "discover thousands of exoplanets in orbit around the brightest stars in the sky," according to the TESS website. The European Space Agency's Planetary Transits and Oscillations of stars (PLATO) mission, planned for launch in 2024, will also search for a large number of exoplanets.

Atlantis ~ True Story or Cautionary Tale?

An illustration by Sir Gerald Hargreaves shows a utopian scene on a cove of the mythical land of Atlantis. Many scholars think Plato invented the story of Atlantis as a way to present his philosophical theories.

If the writing of the ancient Greek philosopher Plato had not contained so much truth about the human condition, his name would have been forgotten centuries ago.

But one of his most famous stories—the cataclysmic destruction of the ancient civilization of Atlantis—is almost certainly false. So why is this story still repeated more than 2,300 years after Plato's death?

"It's a story that captures the imagination," says James Romm, a professor of classics at Bard College in Annandale, New York. "It's a great myth. It has a lot of elements that people love to fantasize about."

Plato told the story of Atlantis around 360 B.C. The founders of Atlantis, he said, were half god and half human. They created a utopian civilization and became a great naval power. Their home was made up of concentric islands separated by wide moats and linked by a canal that penetrated to the center. The lush islands contained gold, silver, and other precious metals and supported an abundance of rare, exotic wildlife. There was a great capital city on the central island.

There are many theories about where Atlantis was—in the Mediterranean, off the coast of Spain, even under what is now Antarctica. "Pick a spot on the map, and someone has said that Atlantis was there," says Charles Orser, curator of history at the New York State Museum in Albany. "Every place you can imagine."

Plato said Atlantis existed about 9,000 years before his own time, and that its story had been passed down by poets, priests, and others. But Plato's writings about Atlantis are the only known records of its existence.

Possibly Based on Real Events?

Few, if any, scientists think Atlantis actually existed. Ocean explorer Robert Ballard, the National Geographic explorer-in-residence who discovered the wreck of the Titanic in 1985, notes that "no Nobel laureates" have said that what Plato wrote about Atlantis is true.

Still, Ballard says, the legend of Atlantis is a "logical" one since cataclysmic floods and volcanic explosions have happened throughout history, including one event that had some similarities to the story of the destruction of Atlantis. About 3,600 years ago, a massive volcanic eruption devastated the island of Santorini in the Aegean Sea near Greece. At the time, a highly advanced society of Minoans lived on Santorini. The Minoan civilization disappeared suddenly at about the same time as the volcanic eruption.

But Ballard doesn't think Santorini was Atlantis, because the time of the eruption on that island doesn't coincide with when Plato said Atlantis was destroyed.

Romm believes Plato created the story of Atlantis to convey some of his philosophical theories. "He was dealing with a number of issues, themes that run throughout his work," he says. "His ideas about divine versus human nature, ideal societies, the gradual corruption of human society—these ideas are all found in many of his works. Atlantis was a different vehicle to get at some of his favorite themes."

The legend of Atlantis is a story about a moral, spiritual people who lived in a highly advanced, utopian civilization. But they became greedy, petty, and "morally bankrupt," and the gods "became angry because the people had lost their way and turned to immoral pursuits," Orser says.

As punishment, he says, the gods sent "one terrible night of fire and earthquakes" that caused Atlantis to sink into the sea.
