10 Weird Science facts you didn't know

Animals can rain from the sky

Raining animals is a meteorological phenomenon, with occurrences reported from many countries throughout history. Sometimes the animals survive the fall, especially fish, suggesting a small time gap between the extraction and the actual drop. Several witnesses of raining frogs describe the animals as startled, though healthy, and exhibiting relatively normal behavior shortly after the event. In some incidents, however, the animals are frozen to death or even completely enclosed in blocks of ice. These occurrences may be evidence for the transport of the victims to high altitudes, where the temperature is below zero, and they show how powerful meteorological forces can be. Most recent occurrences include the rain of frogs and toads in Serbia (2005) and London (1998), and rains of fish in India (2006) and Wales (2004).

In Honduras, the Lluvia de Peces (Rain of Fishes) is a unique phenomenon that has been occurring for more than a century on a yearly basis in the country of Honduras. It occurs in the Departamento de Yoro, between the months of May and July. Witnesses of this phenomenon state that it begins with is a dark cloud in the sky followed by lightning, thunder, strong winds and heavy rain for 2 to 3 hours. Once the rain has stopped, hundreds of living fish are found on the ground. People take the fish home to cook and eat them. Although some experts have tried to explain the Rain of Fishes as a natural meteorological phenomenon, the fish are not sea water fish, but fresh water fish; they are not dead, but alive; they are not blind, they have eyes; they are not big fish, but small; and the type of fish is not found elsewhere in the area. There is no valid scientific explanation for this phenomenon. Many people believe this phenomenon occurs because of Father José Manuel Subirana, a Spanish catholic missionary and considered by many to be a Saint. He visited Honduras from 1856-1864, and upon encountering so many poor people, prayed for 3 days and 3 nights asking God for a miracle to help the poor people by providing food. The Rain of Fishes has occurred ever since.

The universe is beige

Cosmic Latte is the color of the universe, according to a team of astronomers from Johns Hopkins University. In 2001, Karl Glazebrook and Ivan Baldry determined that the color of the universe was a greenish white, but they soon corrected their analysis in "The 2dF Galaxy Redshift Survey: constraints on cosmic star-formation history from the cosmic spectrum", published in 2002. In this paper, they reported that their survey of the color of all light in the universe added up to a slightly beige white. The survey included more than 200,000 galaxies, and measured the spectral range of the light from a large volume of the universe. The hexadecimal RGB value for Cosmic Latte is #FFF8E7.
In a Washington Post article, the color was displayed. Glazebrook jokingly said that he was looking for suggestions for a name for the new color. Several people who read the article sent in suggestions. "Cosmic Latte" was selected.

Poisoning can make masses to dance hysterically

Dancing mania is the name given to a phenomenon that occurred mainly in mainland Europe from the 14th century through to the 17th century, in which groups of people would dance through the streets of towns or cities, sometimes foaming at the mouth or speaking in tongues, until they collapsed from exhaustion. The first major outbreak of the mania was in Aachen, Germany, in July 1374. The dancers went through the streets screaming of wild visions, and even continued to writhe and twist after they collapsed from exhaustion. The dancing quickly caught on, and spread rapidly throughout France and the Low Countries. The mania reached its peak in 1418 in Strasbourg. At at least one point, so many people had either been afflicted with the dancing mania, or caught up in the dancing, or were trying to give assistance, or simply watching the events unfold, that the town was brought to a complete halt.
Although no real consensus exists as to what caused the mania, some cases, especially the one in Aix-la-Chapelle, may have had an explainable physical cause. The symptoms of the sufferers can be attributed to ergot poisoning, or ergotism, known in the Middle Ages as "St. Anthony's Fire". It is caused by eating rye infected with Claviceps purpurea, a small fungus that contains toxic and psychoactive chemicals (alkaloids), including lysergic acid (used in modern times to synthesize LSD). Symptoms of ergot poisoning include nervous spasms, psychotic delusions, spontaneous abortion, convulsions and gangrene; some dancers claimed to have experienced visions of a religious nature.

The Moon is moving away from the Earth

The Moon's orbit (its circular path around the Earth) is indeed getting larger, at a rate of about 3.8 centimeters per year. (The Moon's orbit has a radius of 384,000 km.) The reason for the increase is that the Moon raises tides on the Earth. Because the side of the Earth that faces the Moon is closer, it feels a stronger pull of gravity than the center of the Earth. Similarly, the part of the Earth facing away from the Moon feels less gravity than the center of the Earth. This effect stretches the Earth a bit, making it a little bit oblong.
It is expected that in 15 billion years, the orbit will stabilize at 1.6 times its present size, and the Earth day will be 55 days long equal to the time it will take the Moon to orbit the Earth.

Fly larvae helps to heal wounds quicker

Long ago, some doctors noticed soldiers that had maggots on their wounds healed quicker than those without maggots. Maggots eat the dead skin cells and bacteria. Maggot Therapy (also known as Maggot Debridement Therapy (MDT), larval therapy, larva therapy, or larvae therapy) is the intentional introduction of live, disinfected maggots or fly larvae into non-healing skin or soft tissue wounds of a human or other animal. This practice was widely used before the discovery of antibiotics, as it serves to clean the dead tissue within a wound in order to promote healing.

Animals can naturally explode

Natural animal explosions can occur for a variety of reasons. On 2004, a buildup of gas inside a decomposing sperm whale, measuring 17 meters (56 ft.) long and weighing 50 tons, caused it to burst in Taiwan. The explosion was reported to have splattered blood and whale entrails over surrounding shop-fronts, bystanders, and cars.
A significant population of toads in Germany and Denmark were exploding in April 2005 in an act described as a self-defence mechanism that failed, as it consisted of puffing up to look bigger while under attack by crows.

You can still have an erection once dead

A death erection (sometimes referred to as "angel lust") is a post-mortem erection which occurs when a male individual dies vertically or face-down with the cadaver remaining in this position. During life, the pumping of blood by the heart ensures a relatively even distribution around the blood vessels of the human body. Once this mechanism has ended, only the force of gravity acts upon the blood. As with any mass, the blood settles at the lowest point of the body and causes edema or swelling to occur; the discoloration caused by this is called lividity.
If an individual dies vertically such as in a hanging, the blood will settle in the legs and pool at the feet. The pressure will be greatest as the weight of the blood pushes down. This causes the blood vessels and tissues in the feet to engorge to their greatest elastic capacity and hold the greatest volume of blood possible. This effect occurs right up the legs although to a lesser extent than the feet and is also notable at the waist. The blood which remains in the torso attempts to move to a lower position due to gravity, and as the blood in the waist (which cannot move down due to the legs being full) causes the penis, consisting of erectile tissue, to fill with blood and expand. This is the death erection. As long as the body remains in this position the effect will continue.

Male seahorses can get pregnant

Seahorses reproduce in an unusual way: the male becomes pregnant. Pipefishes and seahorses are the only species in the animal kingdom to which the term "male pregnancy" has been applied.
The male seahorse has a brood pouch in which he carries eggs deposited by the female. The mating pair entwine their tails and the female aligns a long tube called an ovipositor with the male's pouch. The eggs move through the tube into the male's pouch where he then fertilizes them. The embryos develop in ten days to six weeks, depending on species and water conditions. When the male gives birth he pumps his tail until the baby seahorses emerge.
The male's pouch regulates salinity for the eggs, slowly increasing in the pouch to match the water outside as the eggs mature. Hatched offspring are independent of their parents. Some spend time developing among the ocean plankton. At times, the male seahorse may try to consume some of the previously released offspring. Other species (H. zosterae) immediately begin life as sea-floor inhabitants (benthos).

A fetus can get trapped inside of its twin

Fetus in fetu (or Foetus in foetu) describes an extremely rare abnormality that involves a fetus getting trapped inside of its twin. It continues to survive as a parasite even past birth by forming an umbilical cord-like structure that leeches its twin's blood supply until it grows so large that it starts to harm the host, at which point doctors usually intervene. Invariably the parasitic fetus is anencephalic (without a brain) and lacks internal organs, and as such is unable to survive on its own, though it may have almost human (albeit underdeveloped and bizarre) features such as limbs, digits, hair, nails and teeth. Fetus in fetu is such a rare condition that only some 91 cases worldwide have ever been reported. Fetus in fetu happens very early in a twin pregnancy, when one fetus wraps around and envelops the other. The dominant fetus grows, while the fetus that would have been its twin lives on throughout the pregnancy, feeding off its host twin like a kind of parasite. Usually, both twins die before birth from the strain of sharing a placenta. Sometimes, however, the host twin survives and is delivered.

Amazing Photos of an Atomic Blast (taken at 1/1000,000,000 of-a-second)


Harold Edgerton built a special lens 10 feet long for his camera which was set up in a bunker 7 miles from the source of the blast which was triggered Nevada - the bomb placed atop a steel gantry anchored to the desert floor by guide wires. The exposures are at 1/100,000,000ths of a second.


In a millisecond the blast expands; lightning caused by the force of the energy travels down the guide wires The desert floor was turned to glass.





In another millionth of a second, a planet of fire exists, silhouetting and dwarfing the Joshua Trees.

10 Coolest Classic Cars

Pontiac Bonneville Special (1954)

The Pontiac Bonneville Special was a purpose-built concept car unveiled at the General Motors Motorama in 1954, the first 2-seater sports car Pontiac ever produced. Designed by renowned designer Harley J. Earl and hand built by Hommer LaGassey and Paul Gilland, the Special was an experimental car, a two door, grand touring sport coupé that incorporated innovative breakthrough styling like an all-plexi canopy with gull-wing panels on a sleek fiberglass body. Two Special prototypes, one painted metallic bronze and one emerald green, were built with the intention of unveiling them simultaneously at the Grand Ballroom of the Waldorf in New York and the Pan Pacific Auditorium in Los Angeles in 1954.

The design of the Special drew its visual impetus from America's fascination with aeronautic and rocket design in the 1950s, employing a wind-tunnel inspired profile and high-tech bright work throughout the body, hood and grill. Glass covered recessed headlights, like those on the 1953 Corvette, two rows of louvers on the fenders and twin "silver-streaks"[2] on the hood that lead to functional air scoops were it's most distinguishing features. The rear end styling was its most over-the-top visual cue. Featured between two rather bold fender fins were ultramodern twin exhaust chrome-ports, similar to today's Porsches, and a custom spare tire enclosure with space-age wheel disc that gave the car a jet-powered appearance.

Interior styling in the Special was state of the art for its time, and indeed would pass muster against today's computer-designed automobiles. The dashboard was a sleek, wing like design that incorporated a clean horizontal layout of working instruments that gave the interior a futuristic cockpit look. Even underneath the dash, the gauges were sealed in by a contoured metal facia with brushed finish, assuring by Earl that no detail would go unnoticed. Between unique, parabolic shaped, leather bucket seats lay a matching metal, center console with functionally modest gear shift handle, twin vent-control levers, and ignition key slot. Centered over the three spoke, Corvette-style steering wheel was a single, large speedometer that read a top speed of 120 mph.

As of 2006, both cars still exist, belonging to Joseph Bortz of Highland Park, IL. One of the 2 existing 1954 Bonneville Specials was last seen in 2006 Barrett-Jackson Collector Car Auction, selling for $2,800,000 (+8% commission).


De Lorean DMC-12 (1981)

The De Lorean DMC-12 is a sports car which was manufactured by the De Lorean Motor Company from 1981 through 1982. It is most commonly known as the De Lorean, as it was the only model ever produced by the company. The DMC-12 featured gull-wing doors with a brushed stainless steel body. It was famously featured in the Back to the Future trilogy.

The first prototype appeared in March 1977, and production officially began in 1981 at the DMC factory in Dunmurry, Northern Ireland. During its production, several aspects of the car were changed, such as the hood (bonnet) style, wheels and interior. At least 8,500 DMC-12s were made before production ended in 1982, and as of 2006, 6,000 are estimated to still exist.

Despite being produced in Northern Ireland, DMC-12s were primarily intended for the American market. Therefore, all of the production models were left-hand drive (designed to be driven on the right side of the road). Some of them were converted to right-hand drive by specialist mechanics in the United Kingdom, but no right-hand drive De Lorean was ever put into production, thus limiting the vehicle's popularity in the United Kingdom.

Chrysler Thunderbolt (1941)



The year was 1941. Chrysler was a growing company and wanted to show the world that their technology and styling was up to date. Only six of these wild new cars were made and spread across the country for various shows. All of which had different trim and color schemes. It was nicknamed the “pushbutton car” because of its push button feature. A simple push of a button opened up the rear deck lid, doors, and windows without effort. The actual name “Thunderbolt” came from a land speed record car named the Thunderbolt. In 1938 at the Bonneville Salt Flats the twin Rolls-Royce 12 cylinder went an amazing 357.53 M.P.H.! It was then that Captain George Eyston granted Chrysler permission to use the name.

One of the most distinct things you will notice about the Thunderbolt is the slab sides, or smooth sides if you will. It does not have creases or bubbled out fenders. Aerodynamics was somewhat of a factor as much as looks itself. By designing and installing working “hide away” headlights, this car was definitely ahead of it's time!! Lack of body molding and enclosed wheels from the fender skirts also aid in the aerodynamic appearance. Nothing special under the hood for the show cars is known. A 143 horsepower Chrysler 323.5 cubic inch inline eight cylinder engine mated to the Chrysler Fluid Drive transmission powered the vehicle. The actual platform used for this project was a 1940 Crown Imperial. It had very strong structural integrity as you can see from the lack of A pillars. There are only 4 of the original 6 known to still exist.


GM Futurliner Parade of Progress (1950)

One of 12 built by GM, a self-contained display and transport vehicle created by the GM design staff under Harley Earl's direction. Opening side, lighting, retractable stage, distinctive center "cupola" cockpit driving position and dual wheel front axle. Used in the "Parade of Progress" touring exhibit created by "Boss" Kettering that complemented the GM "Motoramas" from 1940 through 1956.

One of only three survivors restored in their original "Parade of Progress" configuration (the others are in long term ownership by NATMUS and Peter Pan Bus Lines), this Futurliner is fully functional and has toured Canada in corporate promotions. Recently returned to its original "Parade of Progress" configuration and colors. Powered by a 400ci GM truck engine and fully equipped including an onboard motor-generator and updated air conditioning for the driver's compartment. A matchless symbol of the American auto industry at the height of its power and influence. One of them was restored in Montreal, Quebec Canada and sold for $4.1 million us at the Barrett-Jackson Collector Car Auction in Jan, 2006.


Chevrolet Corvette (1953)

The Corvette was America's first two-seat sports car. The outer body was made out of a revolutionary new composite material called fiberglass, selected in part because of steel quotas left over from the war. Underneath that radical new body were standard Chevrolet components, including the "Blue Flame" inline six-cylinder truck engine, two-speed Powerglide automatic transmission, and drum brakes from Chevrolet's regular car line. Though the engine's output was increased somewhat, thanks to a triple-carburetor intake exclusive to the Corvette, performance of the car was decidedly lackluster.

In 1954, sales were still low, and GM was seriously considering shelving the project, but the influence of a Soviet emigré in GM's engineering department, Zora Arkus-Duntov, changed all. Arkus-Duntov simply took the new V8 and backed it with a three-speed manual transmission. That modification, probably the single most important in the car's history, helped turn the Corvette from a two-seat curiosity into a genuine performer. It also earned Arkus-Duntov the rather inaccurate nickname "Father of the Corvette."


Oldsmobile F-88 (1954)

In the late fifties, Harley Earl, Bill Mitchell, Ken Pickering and Zora Duntov were creating a roadster for Oldsmobile. They began the project by designing several showcars which were breathtaking and daring, especially compared to the Oldmobile aesthetic. Due to the poor sales of the Corvette, the car which inspired these GM Concepts, the F-88 project was cancelled at the conceptual phase. Before that time however, four very unique Oldsmobiles were completed.

At the 2005 Barrett-Jackson Auction, the sole surviving F-88 concept car sold for $3,240,000 USD. The General Motors concept car lasted through a fierce bidding war to become the highest selling car ever at the Barrett-Jackson auction (at the time).


Chevrolet Camaro (1967-1969)

The Chevrolet Camaro was introduced in North America by the Chevrolet Motor Division of General Motors at the start of the 1967 model year as competition for the Ford Mustang. Camaro advertising would first be found on AM top-40 stations of the day - stations which appealed to young adults. Although it was technically a compact car (by the standards of the time), the Camaro, like the entire class of Mustang competitors, was soon known as a pony car. It may also be classified as an intermediate touring car, a sports car, or a muscle car. The car shared the same platform and major components with the Pontiac Firebird, also introduced in 1967. Production of both cars ceased in 2002 with only the Camaro going back into production in 2009.

The Camaro was the flagship for Chevrolet, and was for many years one of its most popular models. If its frequent inclusion in automotive enthusiast magazines is any indication, the Chevy Camaro is one of the most popular cars for modification in automotive history.


Plymouth Hemi Cuda (1971)

From 1966-71, Dodge stuffed the massive Hemi into small E-Bodies and the 1970 Hemi Cuda is widely accepted as one of the quickest and most saught after of these. Only 652 were built when new, including 14 rare convertibles, making an original Hemi 'Cuda a rare sight. These cars were forced in scarcity due to the extra $900 it cost to build one, nearly a third of the standard purchase price. At $250, the 390 bhp 440 V8 became the norm and made the Hemi Cuda an exception.

The long list of options made available for 1970 Barracudas included such goodies as rallye wheels, a range of exciting colors sich as Plum Crazy, pistol grip shifters, hockey stick sport stripes, hood pins and a variety of creature comforts. But of all the options, the R-code steet Hemi 426 was it, the most legendary muscle car engine ever made. It usually delivered 425 bhp through the solid 727 Torqueflight automatic and a 3.55:1 Sure Grip rear axle. That is, unless the car was one of the 284 that got a 4-speed manual.

With their classic shape, tire-shredding American power, limited production and huge popularity a 1970 Hemi 'Cuda can easily fetch over $150 000 USD. This is a remarkable amount for a car with the same build quailty as a mass-produced Plymouth. However, the aggressive sound of Hemi combined with visual street cred and Barrett-Jackson publicity now make these Cudas more expensive than most Ferraris produced in the same era.

Changes for 1971 were minimal and included a more complex 6 inlet grille design and fender gill louvers. Only 100 or so of these were built and the seven ultra-rare 1971 convertibles are the most expensive muscle cars money can buy. In 72, the government and EPA kicked the muscle car in the ass with emissions regulations. After that time, no more Hemi or more big block models could be ordered.


Ford Mustang (1964-1970)

The Ford Mustang was originally based on the Ford Falcon compact. The first production Mustang, a white convertible with red interior rolled off the assembly line in Dearborn, Michigan on March 9, 1964. Introduced to the public at the New York World's Fair on April 17, 1964, and via all three American television networks on April 19, it was the most successful product launch in automotive history, setting off near-pandemonium at Ford dealers across the continent.

Mustang inspired the term pony car and prompted many imitators. The Mustang's combination of sporty design, low price, and overall performance allowed it to sell over one million units in its first 18 months on the market. After a number of different generations and redesigns, the Mustang remains available today.


Chrysler D'Elegance (1952)

The d'Elegance joins the family of Chrysler experimental cars as another interpretation of sports car styling combined with practical passenger car fundamentals. Designed with emphasis on the American concept of comfort and handling, the d'Elegance shows what can be done with the sports type of Coupe so popular in Europe.

This three-passenger Coupe was entirely styled by the Engineering division of Chrysler Corporation. Ghia –a custom builder in Turin, Italy –hand formed the metal body from drawings and a 3/8 scale plastic model supplied by Chrysler engineers. The body is mounted on a Chrysler New Yorker chassis which is standard except for a modification in wheelbase to 115 inches.

In 1998, the showcar Chrysler Chronos was a modern interpretation of the D'Elegance. And today, the new Chrysler 300 designed by Tom Gale is heavily influenced by the d'Elegance. Few cars in history, if any, have influenced over 50 years of automobile design.

10 Most Fascinating Galaxies of our Universe

The Sombrero Galaxy

The Sombrero Galaxy (also known as M104 or NGC 4594) is an unbarred spiral galaxy in the constellation Virgo. It has a bright nucleus, an unusually large central bulge, and a prominent dust lane in its inclined disk. The dark dust lane and the bulge give this galaxy the appearance of a sombrero. The galaxy has an apparent magnitude of +9.0, making it easily visible with amateur telescopes. The large bulge, the central supermassive black hole, and the dust lane all attract the attention of professional astronomers.


Black Eye Galaxy

A spiral galaxy in the Coma Berenices constellation, Messier 64, the famous "Black Eye" galaxy or the "Sleeping Beauty galaxy," has a spectacular dark band of absorbing dust in front of the galaxy's bright nucleus. It is well known among amateur astronomers because of its appearance in small telescopes.

2MASX J00482185-2507365 occulting pair

The 2MASX J00482185-2507365 occulting pair is a pair of overlapping spiral galaxies found in the vicinity of NGC 253, the Sculptor Galaxy. Both galaxies are more distant than NGC 253, with the background galaxy, 2MASX J00482185-2507365, lying at redshift z=0.06, and the foreground galaxy lying between NGC 253 and the background galaxy (0.0008 < z < 0.06). This pair of galaxies illuminates the distribution of galactic dust beyond the visible arms of a spiral galaxy. The heretofore unexpected extent of dust beyond the starry limits of the arms, shows new areas for extragalactic astronomical study. The dusty arms extend 6 times the radii of the starry arms of the galaxy, and is shown silhouetted in HST images against the central and core sections of the background galaxy.


The Whirlpool Galaxy

Also known as Messier 51a, M51a, or NGC 5194, the Whirlpool Galaxy is an interacting grand-design spiral galaxy located at a distance of approximately 23 million light-years in the constellation Canes Venatici. It is one of the most famous spiral galaxies in the sky. The galaxy and its companion (NGC 5195) are easily observed by amateur astronomers, and the two galaxies may even be seen with binoculars. The Whirlpool Galaxy is also a popular target for professional astronomers, who study it to further understanding of galaxy structure (particularly structure associated with the spiral arms) and galaxy interactions.


Grand spiral galaxy

Also known as NGC 123, this fascinating galaxy is dominated by millions of bright stars and dark dust, caught up in a gravitational swirl of spiral arms rotating about the center. Open clusters containing bright blue stars can be seen sprinkled along these spiral arms, while dark lanes of dense interstellar dust can be seen sprinkled between them. Less visible, but detectable, are billions of dim normal stars and vast tracts of interstellar gas, together wielding such high mass that they dominate the dynamics of the inner galaxy. Invisible are even greater amounts of matter in a form we don't yet know - pervasive dark matter needed to explain the motions of the visible in the outer galaxy.

Supernova 1987A

Two decades ago, astronomers spotted one of the brightest exploding stars in more than 400 years: a doomed star, called Supernova 1987A. This image shows the entire region around the supernova. The most prominent feature in the image is a ring with dozens of bright spots. A shock wave of material unleashed by the stellar blast is slamming into regions along the ring's inner regions, heating them up, and causing them to glow. The ring, about a light-year across, was probably shed by the star about 20,000 years before it exploded. In the next few years, the entire ring will be ablaze as it absorbs the full force of the crash. The glowing ring is expected to become bright enough to illuminate the star's surroundings, providing astronomers with new information on how the star expelled material before the explosion. The image was taken in December 2006 with Hubble's Advanced Camera for Surveys. (Credit: NASA, ESA, and R. Kirshner; Harvard-Smithsonian Center for Astrophysics)


Galaxy NGC 1512

A barred spiral galaxy located some 30 million light years away toward the constellation Horologium, Galaxy NGC 1512 is bright enough to be seen with amateur telescopes. The galaxy is some 70,000 light years across, which is nearly as large as our own Milky Way galaxy. The core of the galaxy is remarkable for its "circumnuclear" starburst ring, which is an amazing circle of young star clusters that spans some 2400 light years across. Galaxy "starbursts" are episodes of vigorous formation of new stars and are found in various galaxy environments.


Galaxy NGC 3370

A dusty spiral galaxy located some 98 million light years away toward the constellation Leo, the center of NGC 3370 shows well delineated dust lanes and an uncommonly ill-defined nucleus. This view of NGC 3370 was obtained by the Hubble Space Telescope using the Advanced Camera for surveys and is sharp enough to identify individual Cepheid variable stars in the galaxy. Cepheid variable stars are used to establish extragalactic distances. In 1994, a Type Ia sypernova exploded in NGC 3370. (Credit: NASA, The Hubble Heritage Team and A. Riess; STScI)


M81

The big and beautiful spiral galaxy M81, in the northern constellation Ursa Major, is one of the brightest galaxies visible in the skies of planet Earth. This superbly detailed view reveals its bright nucleus, grand spiral arms and sweeping cosmic dust lanes with a scale comparable to the Milky Way. Hinting at a disorderly past, a remarkable dust lane runs straight through the disk, below and right of the galactic center, contrary to M81's other prominent spiral features. The errant dust lane may be the lingering result of a close encounter between M81 and its smaller companion galaxy, M82. Scrutiny of variable stars in M81 (aka NGC 3031) has yielded one of the best determined distances for an external galaxy -- 11.8 million light-years.


Hoag's Object

A non-typical galaxy of the type known as a ring galaxy, the appearance of Hoag's Object has interested amateur astronomers as much as its uncommon structure has fascinated professionals. Is this one galaxy or two? This question came to light in 1950 when astronomer Art Hoag chanced upon this unusual extragalactic object. On the outside is a ring dominated by bright blue stars, while near the center lies a ball of much redder stars that are likely much older. Between the two is a gap that appears almost completely dark. How Hoag's Object formed remains unknown, although similar objects have now been identified and collectively labeled as a form of ring galaxy. Genesis hypotheses include a galaxy collision billions of years ago and perturbative gravitational interactions involving an unusually shaped core. The above photo taken by the Hubble Space Telescope in July 2001 reveals unprecedented details of Hoag's Object and may yield a better understanding. Hoag's Object spans about 100,000 light years and lies about 600 million light years away toward the constellation of Serpens. Coincidentally, visible in the gap is yet another ring galaxy that likely lies far in the distance.

Another 11 Fascinating LEGO Creations

LEGO Pharaoh on the Thames

One of the largest Lego creations ever constructed is a 16-ft-tall model of an Egyptian pharaoh that looks suspiciously like King Tut. The giant pharaoh stood floating down the River Thames on its way to Legoland in Windsor, England, where it was the centerpiece of Legoland's Kingdom of the Pharaohs, which opened on March 21, 2009. The pharaoh required more than 200,000 Lego bricks and weighs one ton.


WALL-E LEGO

Created by bazmarc at Trossen Robotics, the WALL-E LEGO is fully automated and animated and programed using Labview's NXT-G software. It was entirely made of Lego parts and Lego NXT Mindstorms Robotic System for brains.


Venice in LEGO

This amazing version in LEGO of Venice, Italy, shows its water canal-laced landscape, complete with the Grand Canal and even St. Mark's Square.

LEGO Dome of the Rock

Arthur Gugick created this beautifully detailed Dome of the Rock rendered in LEGO.


C3PO and a Clone Wars Trooper in LEGO

These great, life-sized Lego models of C3PO and a Clone Wars Trooper were presented at the annual Toy Fair in 2008. Gizmodo reports it's "a big secret" how many Lego bricks it took to construct each one, but we couldn't care less, they look amazing.


Yamato Battleship in LEGO

Japanese LEGO craftsman Jun Brick recreated the famous Japanese Battleship Yamato in Lego form (the real World War II-era one, not the space battleship). He has documented the building-in-progress on his site, which took six years and four months in total. In some ways the making of might be more interesting than the final product, which is nonetheless impressive. The superstructure aircraft carrier measures with a length of over 21 feet and and a height of over three feet. It weighs in at over three hundred thirty pounds.



6-foot-tall Jesus LEGO Statue

Parishioners at a church in Sweden celebrated Easter 2009 by unveiling a 6-foot-tall (1.8-meter-tall) statue of Jesus that they had built out of 30,000 Lego blocks. It took the 40 volunteers about 18 months to put all the tiny plastic blocks together, and their creation shows a standing Jesus facing forward with his arms outstretched. The work, a copy of Danish sculptor Bertel Thorvaldsen's Resurrected Christ, took 1 1/2 years to construct.


LEGO Space shuttle

Two Japanese LEGOsmiths used a whopping 65,000 bricks and 1,590 man hours to complete the stunning diorama, which even simulates a launch with flashing lights under the boosters and a vocal countdown. The only thing it doesn't do is lift off. As part of the “Nasu Space Center,” the Lego Space shuttle appeared as a scene in Nasu Highland Park, an amusement park in Japan.
