Rare And Unusual Rectangular Galaxy Found By Astronomers

The star gazers - from Australia, Germany, Switzerland and Finland - discovered the quirky cosmic phenomenon within a group of 250 galaxies some 70 million light years away.A rare rectangular galaxy with a striking resemblance to an emerald cut diamond has been discovered by astronomers.

‘In the Universe around us, most galaxies exist in one of three forms - spheroidal, disc-like, or lumpy and irregular in appearance,’ said Associate Professor Alister Graham from Swinburne University of Technology in Australia.

Associate Professor Alister Graham said ‘It's one of those things that just makes you smile because it shouldn't exist, or rather you don't expect it to exist.It's a little like the precarious Leaning Tower of Pisa or the discovery of some exotic new species which at first glance appears to defy the laws of nature.’ and he added the rare rectangular-shaped galaxy was a very unusual object.

However, the astronomers suspect it is unlikely that this galaxy is actually rectangular in shape. Instead, they believe that it may resemble an inflated disc seen side on, like a short cylinder.
Support for this scenario comes from observations with the giant Keck Telescope in Hawaii, which revealed a rapidly spinning, thin disc with a side-on orientation lurking at the centre of the galaxy. The outermost measured edge of this galactic disc is rotating at a speed in excess of 100,000 kilometres per hour (62,000mph).

‘One possibility is that the galaxy may have formed out of the collision of two spiral galaxies,’ said Swinburne's Professor Duncan Forbes, co author of the research. The unusually shaped galaxy was detected in a wide field-of-view image taken with the Japanese Subaru Telescope for Swinburne astrophysicist Dr Lee Spitler, who was actually using it to look for something else.

A widely held theory is that galaxies grow via mergers, most often as bigger galaxies consume their smaller companions. In fact, our Milky Way galaxy shows signs of recent snacking on one of its dwarf companions. The rectangular galaxy is something of a hybrid, though, because it shows characteristics of two established types of galaxy mergers.

Elliptical galaxies tend to lack the ingredients for making new stars, so computer simulations show that when two ellipsoids merge, the galaxies form similar—if less extreme—boxy shapes and have little star-forming activity.

By contrast, the models show that galaxies with lots of star-forming gases don't become rectangular after they merge, but they do exhibit fresh rounds of star formation. The Subaru image, however, revealed that LEDA 074886 has both a geometric outline and an inner disk of star formation. The unusual dwarf galaxy may therefore help astronomers model more complex types of galaxy mergers.

Ben Moore, a theoretical physicist at the University of Zurich and a study co-author, already had plans to model the formation of LEDA 074886 on a supercomputer later this year. Those simulations will help determine, for example, how long the galaxy will keep its boxy shape, Graham said. In space, diamonds aren't forever: Unless LEDA 074886 merges with yet another perfectly aligned galaxy, it may lose its well-defined corners over the next billion years.

India To Experience 3D With Help Of BenQ

The Taiwanese screen technology company, is getting up its Indian existence by presenting new items in the pieces it is already present in as well as presenting modern pieces from its international selection.

""This season, in 2012, we are planning to release our green energy enterprise in Indian with PV web theme, and broadening our specialist equipment enterprise here,"" said Adrian Alter, chief executive, BenQ Asia Hawaiian Business, which protects the Center China as well. He included that for when, they do not strategy to generate specialist consumables into Indian.

""We are also looking at establishing up an e-commerce center for our English-speaking marketplaces, here in Indian,"" Alter included. Rajeev Singh, nation head and gm, BenQ Indian Pvt Ltd, the completely run additional, said this center would be in Gurgaon for attentive BenQ team needs.













Referring to its Indian enterprise, Singh said, ""In Indian, we provide projectors mainly for institutional use, such as for academic use. Now, we strategy to generate items for the individual customer.""

Among the new items planned for release in Indian this 30 days are the Fantastic Corrt or GP2, a stream-lined LED projector, focused at the individual section. This product, with an MRP of Rs. 38,000, will be available in Apple shops in The european union and Asia at the same time, Alter included. The W7000, focused at the amusement section, is a 3-D, full HD projector whose cost is predicted to be unveiled better its release later this 30 days.

Meanwhile, it will also release a variety of digital cameras in Indian. ""We presented our variety of digital cameras in Indian about six months ago and we provide them through online TV shopping and change programs. Since we had affordable sales of just five designs of our digital cameras last season, we strategy to generate more designs, all below the digital SLR, in a cost number of Rs. 4500-Rs. 15,000,"" Singh said.

North America Won't Erode Away

Like lines in a greatly endured deal with, the breaks and fissures in the Planet's brown crust area expose a extensive and tumultuous life-time. Large continent-bearing clothing have come together and damaged apart, setting off earthquakes and volcanic breakouts that have fragmented hidden mountain, changing the deal with of the planet over huge generations.

Despite a geologically fractious historical past, Planet's firm surface, or lithosphere, maintains historic segments known as cratons in which rubble have been left relatively secure since they established huge generations ago. These cratons typically occur at the center of ls landmasses, and contain some of Planet's most historic rubble. How these cratons have live through on Planet's exterior, staying away from devastation by both plate-tectonic procedures and loss over huge generations, has been of interest to geologists for many.
In a new paper released today in Scientific disciplines, experts at MIT have refurbished the historic historical past of the Wy State, one of the most historic pieces within the South National craton. The group discovered that at this site, the ls brown crust area knowledgeable a short, extreme interval of loss between 1.8 and 1.5 thousand generations ago before reducing into a more constant interval that has continued to the present day. They did this by creating a novel strategy to determine when areas move from higher to low charges of loss, which they say could also be used in other parts of the world to restore identical backgrounds.

“In our ls public, the most constant parts have been exactly this way for huge generations,” says head writer Terrence Blackburn, a scholar student in MIT’s Office of Soil, Atmospheric and Planetary Sciences (EAPS). “Today the South National craton is deteriorating very gradually, and our information tell us parts like that have been acting like that for bulk of Planet's historical past.”

Blackburn proved helpful with fellow workers at MIT and the School of Co to examine examples from the South National craton in a location of Mt where two ls pieces collided 1.8 thousand generations ago, growing a hill variety. Scientists have discovered that eventually the hill variety evaporated — first quickly, then much more gradually, over a thousand generations or more.

To determine exactly when this move in loss occurred, the group proved helpful to restore the warm historical past of lower crustal xenoliths — pieces of brown crust area that lived deep within the lithosphere for huge generations before relatively recent volcanic activity brought them to the exterior. Blackburn and his fellow workers reasoned that the quantity of loss on the exterior impacts the quantity of warm getting out of from further in Planet's crust: Like eliminating a person's hat, deteriorating a mountaintop lets more warm break free. The group then developed a new strategy to determine the quantity at which these xenoliths refrigerated over more than a thousand generations.
The experts refurbished the warm historical past of these once-deeply hidden examples, using a radiometric relationship strategy that quotes time at which rubble form. The strategy methods the radioactive corrosion of uranium into head to determine an absolute age of events in Soil historical past.

In a small perspective on the strategy, Blackburn and his fellow workers targeted on relationship nutrient deposits that lose radioactive head at higher conditions — the warmer a mountain, the more head diffuses out. Only when the mountain cools down will the nutrient begin to maintain head, successfully starting a radiometric “clock.” This temperature-sensitive relationship strategy is known as “thermochronology.” By creating the moment and quantity of air conditioning within the lithosphere, the group was able to restore the warm progress of the lithosphere, and infer the quantity of loss the location knowledgeable.
“This information set we have informs us for initially what is the maximum length at which fast loss of topographically higher mountain range can last,” Blackburn says. “It’s just a portion of the craton’s life-time, three hundred thousand generations at most, before the hill devices are compressed, and after that, loss is very slow.”

Blackburn says the new strategy may be used to restore the backgrounds of other ls public. “Cratonic parts comprise areas of extensive run balance,” says Troy Rasbury, affiliate lecturer of geosciences at the State School of New You are able to, Stony Stream, who was not include in the study. “The balance is not a surprise, but the extremely low charges of uplift is a unexpected result. This approach is very appropriate to other craton parts and it will be exciting to see if they all give identical results.”

UFO In Gagarin Said 2 eyewitness

Oh god now its in Russia too guys ya its true UFO sitting in Russia isnt it amazing there are lots and lots of UFO sitting in the present times so guys what do all you guys think of an UFO. certainly i dont have a clue do you guys have any then hit a mail to me guys. so okay now lets come to the main part.A total of six passenger planes have reported seeing a UFO near the town of Gagarin in western Russia.

A burning object, a smoke trail and six mysterious red dots were reportedly seen in the sky over two Russian towns.One, a pilot on a commercial flight from London to Moscow, claimed to see a 'burning object' followed by a trail of smoke going at high speed over the town, which was named after Yuri Gagarin, the first man in space.Hundreds of miles away in SIberia, six red dots were reportedly seen an hour after the Gagarin 'sightings'.
An hour later, six red dots were seen in the sky, hundreds of kilometres away in Siberia. "Leaving a supermarket with my daughter, I saw six moving red dots in the sky. First, it crossed the sky from west to east, then one flew separately, and the rest at some point stayed almost on the same spot," a witness, Andrey Filipov, said.

The Russian Defence Ministry denied any stray missiles or other military objects were in the vicinity of Gagarin at around 7.30pm local time last Thursday.

Mystery Closes Over A 2,000 Year Old Supernova

In 185 A.D., Chinese astronomers witnessed what they called a mysterious "guest star" that appeared in the sky and lingered for about eight months. It wasn't until the 1960s that scientists determined that this cosmic object was the first documented observation of a supernova that signaled the violent death of a distant star.Now, infrared views of the supernova from NASA's Spitzer Space Telescope and the Wide-field Infrared Survey Explorer (WISE) reveal that the star explosion detonated inside a region of space that was relatively free of gas and dust. This allowed the star's explosion to travel out much farther and faster than expected, researchers said.

"This supernova remnant got really big, really fast," said Brian Williams, an astronomer at North Carolina State University in Raleigh, in a statement. "It's two to three times bigger than we would expect for a supernova that was witnessed exploding nearly 2,000 years ago. Now, we've been able to finally pinpoint the cause."Space telescope observations now suggest that before exploding, a wind of material from the star blew a cavity around it, into which the supernova could expand much more quickly.

The findings, published in the Astrophysical Journal, combine existing data from the Chandra X-ray telescope and the XMM-Newton Observatory with recent images from the US space agency Nasa's Spitzer and Wide-field Infrared Survey (Wise) telescopes.Both of these telescopes are sensitive to infrared light, giving a picture of the conditions of material that is at fairly low temperatures in the supernova remnant. The supernova, about 8,000 light-years away, is huge - if the infrared light it emits could be seen by our eyes, it would appear to be as large in the sky as the full Moon.

Taken together, the data show that the supernova initially expanded into a comparatively empty "cavity", meaning its material could quickly expand unimpeded.However, the case is not closed for RCW 86; these cavities are associated only with what are called core-collapse supernovas, but the Chandra and XMM-Newton observations show evidence of a great deal of iron in the remnant - associated instead with Type 1A supernovas.

"Now, with multiple observatories extending our senses in space, we can fully appreciate the remarkable physics behind this star's death throes, yet still be as in awe of the cosmos as the ancient astronomers.""Modern astronomers unveiled one secret of a two-millennia-old cosmic mystery only to reveal another," said Bill Danchi, a programme scientist for the Spitzer and Wise missions.

Dark Matter Mystery Stays Unsolved

A new study deepened the mystery of dark matter, as finding the dark matter in galaxies is spread out smoothly, according to media reports.The study was published Monday in the American scientific journal Astrophysical.Having analyzed the observations of two dwarf galaxies, Fornax and Sculptor, researchers from the Harvard-Smithsonian Center for Astrophysics found that there was no higher concentration in the center of the galaxy than anywhere else.

The finding goes completely against the current cosmological models, which suggest that dark matter should be clustered at the centers of galaxies."After completing this study, we know less about dark matter than we did before. Our measurements contradict a basic prediction about the structure of cold dark matter in dwarf galaxies," said Matt Walker, the study's lead author.Astronomers have one more reason to scratch their heads over the unseen material known as dark matter. Observations of two dwarf galaxies, Fornax and Sculptor, show the dark matter within them is spread out smoothly rather than heaped into a central bulge, contradicting cosmological models.

Researchers know dark matter comprises a far greater percentage of the universe than the ordinary matter making up things like people and stars. Because of this, the distribution of dark matter determines the structure of the cosmos. Galaxies form when they are attracted to and anchored by large clumps of dark matter.The dwarf galaxies Fornax and Sculptor are themselves made of 99 percent dark matter and only 1 percent normal matter. It is impossible to directly see the dark matter but, by observing the rotation of stars around each galactic center, researchers can detect its influence and map out its distribution.According to the current cosmological models, dark matter almost certainly exists, otherwise, galaxy clusters would have no sufficient gravity to hold themselves together.

While simulations suggest that the dark-matter density should increase sharply near the galactic centers, the recent observations found the dark matter spread relatively uniform throughout. Yet if these dwarf galaxies have no “clump” in their center, then what is pinning them in place?Scientists hoped the study on dwarf galaxies could make some breakthrough in dark matter hunting, because calculations suggest dwarf galaxies consisted of 99 percent dark matter.However, the new study has disappointed the researchers, as it has "drawn a big, frustrating blank", Dr. Alastair Wilkins from University of Bristol in Britain remarked in his blog.

Observations of other small galaxies have similarly failed to find a dense central dark matter core, a difficulty that has prompted astronomers to begin expanding their ideas on the mysterious substance.It is possible that dark matter might interact more with ordinary matter than currently thought, allowing the regular matter to stir up the dark matter and spread it out. Alternatively, dark matter might move faster than expected and therefore be less prone to clumping in galactic centers. Either case creates many further mysteries and problems for astronomers to keep mulling over.

Elenin Doomsday Comet Closes Earth

Comet Elenin broke up on August after a huge solar storm blasted it. On September 10 it passed close to the sun which finished it off, so what re-entered the Earth were debris rather than a completely intact comet, astronomers say, adding that what was left of Elenin will not return for 12,000 years.Astronomer Don Yeomans of the Near-Earth Object Program Office at NASA's Jet Propulsion Laboratory said that the comet cannot be found so he believes "it's already dead and gone."

When discovered by astronomer Leonid Elenin in December 2010, the passing of the 3-5 km wide chunk of space ice was predicted to be the astronomical event of the year, which in turn inspired an overkill of apocalyptic theories.Amateur astronomers and conspiracy theorists put forth the idea that Comet Elenin was responsible for a variety of anomalous events seen throughout 2011; from the scattered outbursts of political uprisings to the earthquake in Japan.

While it brought fear to some who believed that Comet Elenin would bring the Earth to extinction, astronomers now say that only a stream of debris of the supposedly "doomsday comet" have reached the atmosphere.Various predictions came about when news about the "doomsday comet" was reported.Some rumors that started circulating that Elenin would wreck havoc to the Earth, causing massive earthquakes and tsunamis, after it aligns with other heavenly bodies. Another said that Elenin was not a comet but in fact a planet called Nibiru, and that it would bring the end of the world. Despite being purported to potentially affect Earth phenomena, natural disasters or tides, Comet Elenin passed by at about 90 times the distance of the moon. Elenin is about one-hundredth the size of the moon.

“People like to play on the fact that there are a lot of ‘maybes’ with these ‘unknown’ phenomena,” he continued. “But the truth is there are few maybes; there is a lot of accuracy with understanding space science, more than there is an understanding of what’s at the bottom of the oceans. If there was any issue of concern, NASA or any professional astronomer would be the first to raise the issue.”Comet Elenin will now continue outward, back into space where it came from, with no further events predicted in the foreseeable future. As Nawar put it, “People should move on to their next doomsday theory, this one’s over.”
