Top 5 Logical Reasons Aliens Can Exist

A person who comes from a far-off land is normally called an immigrant, or an outsider, and probably treated like one too, but do we call him an alien? No we don’t. Because the word ‘alien’ in our common consideration is not referred to as a foreigner, but a non humane, frightful, vicious and presumably filthy sort of a thing, belonging to another planet. A thing, one has never seen, but imagined. A thing, no one knows if exists or not. Following are five reasons for you to believe that aliens can exist.


Let’s consider galaxies first. There may be 100,000,000 galaxies, because an estimated 50 billion galaxies are visible with modern telescopes. Every galaxy must have a number of stars in it, as many as hundreds of billions. Now we all know that stars have planetary systems, and with original extra-solar system planet-hunting-technology, we know that stars’ presence detect planets to be near them. This is observed customarily by the stars’ movement. Then it is also a well known fact that the dimming and brightening of a star is when a planet crosses its disk. Also, it is believed that every star has a planetary formation around it. Now if galaxies are there, and every galaxy has planets in it, then there is possibility for planets to have water or some form of life on them. Astrophysicists are already searching for life on other planets

Alien probability with so many stars:

Although there may be no solid proof of life on planets other than Earth, but our universe consists of stars, trillions of stars. And research shows for the past many years now that at least 50 percent of the stars entertain planets.

Some scientists also believe that there maybe chances that some of the stars or their planets may have gone through a development which Earth had gone through and developed life, which scientist refer to as a methodical life. This, according to scientists, one can consider in the pictures of Milky Way, with clusters of youthful stars.

Water be plentiful in our solar system

We all know the importance of water. Water is the vital element for life. It has been discovered that there is abundance of water in our solar system. We can take the recent case in point; facts prove that water may well flow beneath the shell of Mars. Europa, a moon of Jupiter, has also been found to have traces of a liquid ocean on it. And so, why not other moons, like the Jovian moons Callisto and Ganymede may have the same? Especially the moons of Saturn, Titan and Enceladus, may also be watery. Even Venus, as researchers believe it might have a bit of water in its atmosphere. So that pretty much makes a rough sketch encouraging the probability of alien life!

Life flourishes even in extreme environments

Scientists have found life on every part of Earth. Whether they found under the cold, dark depths of the oceans; cuddled up to boiling hot hydrothermal opening; hidden under the Antarctic ice; or dried out in deserts like the Atacama Desert. According to many scientists, life can get used to really hard-hitting environments and, of course, most of the universe is yet going to be crammed with habitation that will be tough. For instance, Mars is an unkind location, but some of the bacteria found on Earth, including the one shown in the picture was discovered in the depths of a mine. So there may be a possibility of such bacteria which could survive underneath the surface of Venus or Mars. These discoveries have allowed scientists to range back to a possibility of an outer space life.

Millions of people claim to have seen an alien

At least a hundred thousand UFO/alien sightings have been recognized over the past 50 years. Some searches show that up to 7% of people in the world have claimed to have seen a UFO and even an alien. Numerous military spokespersons believe to have seen them. TV channels, books, histories and scientific researches make one to consider the possibility of an alien existence. Some well known scientists have also said that whether aliens exist or not, it may be discovered within 20 years or not at all.
According to the many who are scrutinizing the skies for signs of logical life, and regardless of finding nothing they have not lost hope. They still claim to believe on accepted assumptions about the chances of alien civilizations existing. And so accordingly, on projected increases in computing power on Earth the chances of this search will become easier. To find them will involve monitoring and inspecting radio emissions from most of the Milky Way’s 100 billion stars. They believe that within a generation, radio emissions from enough stars will be observed and analyzed to find the first alien civilization.



The Beauty of Ice Caves

Where you have lava tubes or limestone passage ways below the ground, occasionally a rare form of cave evolves – the ice cave. Strange, mysterious and often dangerous they are often difficult to get to and so not seen by huge amounts of people. Take a short tour in to the magical world of the ice cave.


Size, of course, is not everything but let’s start with the largest ice cave on the planet. Translated from the German, the name of the cave is the ‘Word of the Ice Giants’ and to be frank, it is not a piece of Germanic overstatement. Forty kilometers south of Salzburg, Austria in the Hochkogel Mountain the cave stretches for more than forty kilometers. However, the more than two hundred thousand visitors the cave receives each year are restricted to the first kilometer only.

This huge ice cave was formed when the river Salzach drove – over millennia – passageways in to the mountain. One can only imagine the tiny beginnings of the cave and marvel at the sheer tenacious power of water. Why the ice remains throughout the year is fairly straightforward, during the winter, ice cold winds rush in to the cave and freeze the snow that has been blown inside. Contrarily, in the winter, wind from the bowels of the cave blow up to the entrance and ensure that the frozen formations do not melt.

The cave itself was ‘discovered’ in 1879 – locals were well aware of its existence but had never actually explored the interior. There was a simple reason for this. Despite the ice – they believed it to be the entrance to hell. Ice caves are different from glacier caves (people sometimes confuse the two). A glacier cave is a cave that is formed within ice itself rather than in an already existing natural structure.


Demänovská ice cave is situated in the Low Tatra Valley in Slovakia and has been known in Europe since the Middle Ages, first being mentioned in 1299. It is quite off the beaten track so if you like your destinations a little less traveled then it could be ideal for a visit. It is a little known fact that Slovakia is full of caves and this ice cave is one of 44 cave systems in the small eastern European country.

Although the cave was well known it was not until the middle of the 1800s that the caves were first opened to the public. The entrance to the cave was modified to make descent easier and there was even a hostel built to accommodate the tourists of the time. Approximately seven hundred meters is opened to the public nowadays and the tour is quite spectacular – if a little frosty.


There are times when ice caves can look a great deal like glacier caves. This amazing shot was taken by Ian McKenzie of the Alberta Speleological Society in the wonderfully named Serendipity. Serendipity is a limestone ice cave situated in the Canadian Rockies. Within it, water ponds as it freezes and creates enough space for a little reflection. Ponded ice water is what happens when surface water collects in a cave and then freezes. The resulting clear ice mass can be enormous – tens of meters thick – and it can also be hundreds of years old.

The Crystal Ice Cave, California

Ice caves in California? Not exactly what one might expect but the Lava Beds National Monument contains a true cave of wonders. Although there are ice formations in many of the Lava Bed’s numerous caves the ones in the Crystal Ice Cave are the most spectacular – and the weirdest too. The formations are delicate and as such there is a very limited amount of visitors allowed each year.

For three months each year, between December and March, small tours of no more than six people are given each Saturday, which means that the cave is visited by only just over a hundred people each year. It is not for the faint hearted either – visitors are expected to be in excellent physical condition as they well have to use their upper body strength to get down a sheer sloped ice floor on a rope. They must also be able to crawl through small holes and have good coordination. Do you consider it worth the exertions?

Scărişoara, Romania

In the midst of the Carpathian Mountains, this wonderful ice cave was discovered in the eighteenth century and is believed to be around three and a half thousand years old. It is high up – almost twelve hundred meters above sea level and is over a hundred meters deep and seven hundred in length. Despite the freezing temperatures, bats and small insects inhabit the cave.

Kunguruska, Russia

One of the oldest towns in the Urals, Kungar is home to the Kunguruska ice cave. There are over twenty grottos in the cave system, including the Diamond the Polar grottos. Many of the grottos feature unbelievable formations of ice, from solid walls to ‘organ pipes’. The cave itself was thought to have once sheltered an army during a winter invasion of Siberia. There is also an onsite stonemason’s workshop where the history of selenite is explained to visitors.

Fish Creek, Canada

Fish Creek ice cave near Calgary in Canada is an example of how the configuration of the cave allows convection to bring extremely cold air from the surface in the winter but not in the summer. In the winter the cold air settles in the cave and forces any warm air upwards and out of the cave. In the summer the cold air stays exactly where it is as the warm air is lighter and so cannot enter. This makes it what is known as a cold trap.

Tignes, France

Can an ice cave be man made? Perhaps if a tunnel is deserted and left to its own devices. In Tignes, in the Rhone-Alpes region of France, this disused tunnel soon became a wonderful ice cave. Wherever they are found in the world there is no doubt of the strange allure and outstanding beauty of ice caves.



Aerial view Cities at Night

NASA’s Marshall Space Flight Center has an incredible 62-picture album on Flickr that shows stunning views of the Earth at night. All photographs were taken from the International Space Station since May 1st, 2003. Below is a collection of 30 of the most outstanding shots, but we highly recommends you check out the entire album on Flickr:

Aurora Australis Over New Zealand, Tasman Sea

2. Milan, Italy at Night from Space – 02/22/11

The metropolitan area of Milan (or Milano) illuminates the Italian region of Lombardy in a pattern evocative of a patchwork quilt. The city of Milan forms a dense cluster of lights in this astronaut photograph, with brilliant white lights indicating the historic center of the city where the Duomo di Milano (Milan Cathedral) is located. Large dark regions to the south (image left) contain mostly agricultural fields. To the north, numerous smaller cities are interspersed with agricultural fields, giving way to forested areas as one approaches the Italian Alps (not shown). Low, patchy clouds diffuse the city lights, producing isolated regions that appear blurred. The Milan urban area is located within the Po Valley, a large plain bordered by the Adriatic Sea to the south and the Italian Alps to the north. Milan has the largest metropolitan area in Italy, and the fifth largest in the European Union. It is one of Europe’s major transportation, industrial, and commercial hubs, and is also a global center of fashion and culture. It is considered an “alpha” world city by the Globalization and World Cities Research Network

3. Tokyo, Japan at Night from Space – 01/09/11

From 220 miles above Earth, one of the Expedition 26 crew members aboard the International Space Station exposed this night time picture of the metropolitan area of Tokyo, Japan. The large majority of the heavily lighted, highly populated area is Tokyo proper. Yokohama is to the left, below center, along Tokyo Bay.

4. Nile River and the Sinai Peninsula at Night from Space – 08/18/11

5. Europe, and Africa at Night from Space – 10/28/10

The view “looks” northward over Sicily and the “boot” of Italy, with the Mediterranean Sea representing most of the visible water in the view and the Adriatic Sea to the right of center. Tunisia is partially visible at left. Part of a docked Russian spacecraft and other components of the ISS are in the foreground.

6. City Lights, France-Italy Border at night from Space – 04/28/10

City lights at night along the France-Italy border, Europe are featured in this image photographed by an Expedition 23 crew member on the International Space Station (ISS). The brightly lit metropolitan areas of Torino (Italy), Lyon, and Marseille (both in France) stand out amidst numerous smaller urban areas in this dramatic photograph. The image captures the night time appearance of the France-Italy border area between the mountainous Alps to the north (not shown) and the island of Corsica in the Ligurian Sea to the south (top). The full moon reflects brightly on the water surface and also illuminates the tops of low patchy clouds over the border (center). This image was taken by an ISS crew member at approximately 11:55 p.m. local time when the station was located over the France-Belgium border near Luxembourg. Crew members orbiting Earth frequently collect images that include sunglint, or sunlight that reflects off a water surface at such an angle that it travels directly back towards the observer. Sunglint typically lends a mirror-like appearance to the water surface. During clear sky conditions reflected light from the moon can produce the same effect (moon glint) as illustrated in this view. The observer was looking towards the southeast at an oblique viewing angle at the time the image was taken; in other words, looking outwards from the ISS, not straight down towards Earth.

7. Las Vegas, Nevada at Night from Space – 11/30/10

The surrounding dark desert presents a stark contrast to the brightly lit, regular street grid of the developed metropolitan area. The Vegas Strip (center) is reputed to be the brightest spot on Earth due to the concentration of lights associated with its hotels and casinos. The tarmac of McCarran International Airport to the south is a dark feature by comparison. The airstrips of Nellis Air Force Base on the northeastern fringe of the metropolitan area are likewise dark compared to the well-lit adjacent streets and neighborhoods. The dark mass of Frenchman Mountain borders the metropolitan area to the east. Acquisition of focused night time images such as this one requires space station crew members to track the target with the handheld camera while the ISS is moving at a speed of more than seven kilometers per second (15,659 miles per hour) relative to Earth’s surface.

8. Cairo and Alexandria, Egypt at Night from Space – 10/28/10

9. Brasilia, Brazil at Night – 01/08/11)

Whether seen at night or during the day, the capital city of Brazil is unmistakable from orbit. Brasilia is located on a plateau (the Planalto Central) in the west-central part of the country, and is widely considered to be one of the best examples of 20th century urban planning in the world. One of its most distinctive design features-as seen from above-suggests a bird, butterfly, or airplane traveling along a northwest-southeast direction, and is made dramatically visible by city light patterns (center left, directly to the west of Lake Paranoa). Following the establishment of Brasilia in the early 1960s informal settlements began to form around the original planned city. Ceilandia, located to the west of Brasilia, was one such informal settlement. In 1970 the settlement was formalized by the government and is now a satellite city of Brasilia with its own distinct urban identity. The developed areas of Brasilia and its satellite cities are clearly outlined by street grid and highway light patterns at night in this photograph taken from the space station. The large unlit region to the northwest of the city is the Brasilia National Park (lower left); other dark regions to the south and southwest contain agricultural fields and expanses of Cerrado tropical savanna.

10. California’s Bay Area at Night from Space – 12/26/10

11. Night View of India-Pakistan Borderlands from Space – 08/21/11

A night time view of India-Pakistan borderlands is featured in this image photographed by an Expedition 28 crew member on the International Space Station. Clusters of yellow lights on the Indo-Gangetic Plain of northern India and northern Pakistan reveal numerous cities both large and small in this photograph. Of the hundreds of clusters, the largest are the metropolitan areas associated with the capital cities of Islamabad, Pakistan in the foreground and New Delhi, India at the top — for scale these metropolitan areas are approximately 700 kilometers apart. The lines of major highways connecting the larger cities also stand out. More subtle but still visible at night are the general outlines of the towering and partly cloud-covered Himalayan ranges immediately to the north (left). A striking feature of this photograph is the line of lights, with a distinctly more orange hue, snaking across the central part of the image. It appears to be more continuous and brighter than most highways in the view. This is the fenced and floodlit border zone between the countries of India and Pakistan. The fence is designed to discourage smuggling and arms trafficking between the two countries.

12. Montreal at Night from Space – 12/24/10

This photograph of the Montreal, Quebec, Canada metropolitan area (center) illustrates the extent of urbanization made clearly visible by city lights at night. Major roadways and industrial areas are traced by bright white lighting, while the adjacent residential and commercial land uses are characterized by more diffuse yellow-gold lighting. Rivers and other water bodies appear black, while the surrounding rural countryside is faintly illuminated by moonlight. Blurry areas at top and bottom left are caused by cloud cover. Montreal is the largest city in the dominantly French-speaking Province of Quebec. The metropolitan area is the country’s second-largest, having been surpassed by Toronto in 1976. While the city of Montreal proper is located on-and almost completely covers-the Island of Montreal at the confluence of the St. Lawrence (center) and Ottawa Rivers (not visible), the city takes its name from Mont Royal located at the city’s center . Several smaller urban areas form a loose ring around the Montreal metro region: Sorel-Tracy, Saint-Hyacinthe, Saint-Jean-sur-Richelieu, Salaberry-de-Valleyfield, Saint-Jerome, and Joliette are among those that can be readily identified.

13. Istanbul at Night from Space – 12/18/10

14. Northwestern Europe at Night from Space – 08/10/11

While the landscape is dotted with numerous clusters of lights from individual urban areas, the metropolitan areas of London (United Kingdom), Paris (France), Brussels (Belgium) and Amsterdam (Netherlands) stand out due to their large light “footprints”. The metropolitan area of Milan, Italy is also visible at lower left. This photograph was taken with a short camera lens, providing the large field of view recorded in the image. To give a sense of scale, the centers of the London and Paris metropolitan areas are approximately 340 kilometers distant from each other.

15. New Orleans at Night from Space – 01/26/11

16. Baltimore-Washington, D.C. Area at Night from Space – 11/30/10

17. Northern Coast, Gulf of Mexico at Night from Space – 10/29/10

18. Atlantic Coast of Europe Into Africa from Space – 11/05/10

One of the Expedition 25 crew members aboard the International Space Station, 220 miles above Earth, took this night time photo, looking south along the Atlantic coast of Europe and into Africa, from Lisbon, Portugal south across the Strait of Gibraltar. The lights can be followed down the coast of Morocco to Casablanca, and beyond.

19. Southern Italy at Night from Space – 06/11/11

This photograph highlights the night time appearance of the southern Italian Peninsula; the toe and heel of Italy’s “boot” are clearly defined by the lights of large cities such as Naples, Bari, and Brindisi as well as numerous smaller urban areas. The bordering Adriatic, Tyrrhenian, and Ionian Seas appear as dark regions to the east, west, and south of the boot. The city lights of Palermo and Catania on the island of Sicily are visible at image bottom center.

20. Florida Peninsula at Night from Space – 12/28/10

A southerly looking night view of the upper two thirds of the Florida peninsula was recorded by one of the Expedition 26 crew members aboard the International Space Station on Dec. 28, 2010. Cape Canaveral and the Kennedy Space Center are very well lighted on the left (Atlantic Ocean) side of the peninsula. The Tampa-St. Petersburg area is seen on the Gulf of Mexico or right side of the frame. At the bottom or in the north areas of the picture are portions of the state’s panhandle as well as cities and communities in southern Georgia.

21. Houston, Texas from Space – 02/28/10

Houston, Texas has been called the “energy capital of the world” due to its role as a major hub of the petroleum and other energy resource industries. The Houston metropolitan area covers almost 2,331,000 hectares (approximately 9,000 square miles) along the southeast Texas coastline, with an average elevation of 13 meters (approximately 43 feet) above sea level and a population of over 5 million (2006 US Census estimate). The Houston metropolitan area is also noteworthy as being the largest in the US without formal zoning restrictions. This has lead to a highly diverse pattern of land use at the neighborhood scale; nevertheless, more general spatial patterns of land use can be recognized in remotely sensed data. This is particularly evident in night time photography of the urban area taken by crew members onboard the space station. The image depicts the roughly 100 kilometers (approximately 62 miles) east-west extent of the Houston metropolitan area. Houston proper is at center, indicated by a “bull’s-eye” of elliptical white to orange-lighted beltways and brightly lit white freeways radiating outwards from the central downtown area. Suburban and primarily residential urban land use is indicated by both reddish-brown and gray-green lighted regions that reflect a higher proportion of tree cover and lower light density. Petroleum refineries along the Houston Ship Channel are recognized by densely lit areas of golden yellow light. Rural and undeveloped land circles the metropolitan area, and Galveston Bay to the southeast (upper right) provides access to the Gulf of Mexico. Both types of non-urban surface appear dark in the image.

22. Mediterranean Riviera from Space – 11/04/10

23. Florida at Night from Space – 10/31/10

24. Aurora Borealis Over Europe from Space – 11/07/10

25. City of Dubai, United Arab Emirates from Space – 09/11/09

The city of Dubai is the largest metropolitan area in the emirate of Dubai, one of the member states of the United Arab Emirates. Dubai is located along the southern Persian Gulf on the Arabian Peninsula, and its signature city is known for high profile architectural and development projects. Among the most notable is the Palm Island Resort, a manmade peninsula and surrounding islands built from over 50 million cubic meters of sand. Two other island projects, one similar to the Palm Island Resort and another crafted to look like a map of the world, are also underway along the Dubai coastline. This night time photograph of the city of Dubai was taken at approximately 2:00 a.m. local time. Orange sodium vapor lights trace out the major highways and surface street grid in and around the metropolitan area, while grey-white mercury vapor lamps fill in the commercial and residential areas. The lighted islands and peninsula of the Palm Island Resort are clearly visible along the coastline. An interesting spiral pattern of lights on the southeastern fringe of the urban area is a camel racetrack.

26. Capetown, South Africa at Night from Space – 11/15/10

27. Sao Paulo, Brazil, at Night from Space – 04/12/03

This image shows the sprawling urban footprint of São Paulo, Brazil, South America’s largest city with roughly 17 million people. The different colors (pink, white, and gray) define different types and generations of streetlights. The port of Santos, on the right side of the photograph, is also well defined by lights.

28. London at Night from Space – 02/04/03

29. California, Mexico’s Baja California & the Gulf of Cortez from Space 08/19/11

30. Aurora Australis Over Indian Ocean from Space – 09/17/11
