Outer space comprises the relatively empty regions of the universe outside the atmospheres of celestial bodies. Outer space is used to distinguish it from airspace and terrestrial locations.

Contrary to popular understanding, outer space is not completely empty (i.e. a perfect vacuum), but contains a low density of particles, predominantly hydrogen plasma, as well as electromagnetic radiation and neutrinos. Hypothetically, it also contains dark matter and dark energy.

Outer space is the closest approximation of a perfect vacuum. It has effectively no friction, allowing stars, planets and moons to move freely along ideal gravitational trajectories. However, no vacuum is truly perfect, not even in intergalactic space where there are still a few hydrogen atoms per cubic centimeter.
(For comparison, the air we breathe contains about 1019 molecules per cubic centimeter.) The deep vacuum of space could make it an attractive environment for certain industrial processes, for instance those that require ultra clean surfaces.

All of the observable universe is filled with large numbers of photons, created during the Big Bang, the so-called cosmic background radiation, and quite likely a correspondingly large number of neutrinos called the cosmic neutrino background. The current temperature of the photon radiation is about 3 K (−270.15 °C; −454.27 °F).

Many people ask that if we put a thermometer in Space with no other light or heat source around and absolutely no background radiation there, what it would read. Would the temperature be really cold or what?

Yes, it would be really cold. Temperature measures the energy per “degree of freedom” (i.e. way something can move) of whatever molecules happen to be around. So, it becomes so cold that the molecules stop all together, and then this is the “absolute zero” temperature. On the Celsius Temperature Scale (i.e. water freezes at 0, and boils at 100), this takes place at -273 degrees C.

We usually use the Kelvin temperature scale, where Zero Kelvin is this “absolute zero” temperature -- or -273 degrees C. Water freezes at +273 Kelvin and water boils at +373 Kelvin.

If we put a thermometer in darkest space, with absolutely nothing around, it would first have to cool off. This might take a very long time. Once it cooled off, it would read 2.7 Kelvin. This is because of the “3 degree microwave background radiation”. No matter where you go, you cannot escape it -- it is always there.

Astonishing reports are surfacing of eye-witness accounts and information that there may be a hidden alien base on the moon. There’s a far side of the moon that is forever hidden from our view, anything could be back there. Why have we stopped going to the moon? Shouldn’t we build that moon base we’ve always talked about? It seems a lot more logical than putting a space station out in the middle of nowhere; cut off from resources, supplies and raw materials.

It may not be so far-fetched. A naval Intelligence Officer, Milton Cooper, reports that not only does the Alien Base exist on the Moon, but we’ve got a name for it! “Luna” is a mining operation on the moon and aliens make trips to Earth in flying saucers every now and again. The Apollo astronauts actually filmed the base. There are huge machines and large alien craft.

Shortly after making their historic landing on the Moon, both Edwin "Buzz" Aldrin and Neil Armstrong saw UFO’s. Anonymous radio hams received broadcasts that bypassed NASA using their own VHF receivers that corroborate the report.

The first to confirm the incident (allegedly) were soviet scientists. NASA censored the message in which one scientist, Dr. Vladimir Azhazha, a physicist and Professor of Mathematics at Moscow University stated that Neil Armstrong relayed the message that two large objects were watching them after they had landed. Buzz Aldrin supposedly recorded it on color film. The UFOs departed after a few minutes.

So why all the hush, hush? What is the reason that we are not allowed to know about the Moon UFO’s? When it is obvious that reasonable activity of some extra-terrestrial civilization showed up unexpected and nearby, why do we get shut out of knowing something that amazing? Experts say that we are not psychologically ready for it. There are masses of books, literature, and other publications that beg the question of “are we alone?” According to those who believe the reports, there is actual physical proof waiting for us just behind the moon.

When the film about the astronauts trip to the Sea of Storms was shown in 1969, the astronauts again saw strange objects. These were explained as “striped glasses” by NASA officials. An astronaut, after returning, explained his feeling of not being alone. He said that he kept feeling the need to look over his shoulder.
An expert at the Houston Space Center studied photos and videos from the Apollo missions and during discussions had mentioned that NASA was terribly annoyed by the number of anomalous objects discovered on the Moon.

There are astonishingly geometric structures that resemble ancient ruined cities. A mission control specialist noted the structures in photos and said that there were ruins of Lunar cities, pyramids that appeared to be transparent, domes and so much else. The photos themselves are locked away in NASA vaults. Geologists and scientists agree that they cannot be natural formations as they are too regular.

It’s up to you to decide what is fact and what is fiction. Are we really not ready to handle it if there exists life outside our own planet?

Space, to a great extent, is very much in the realm of the occult. Notwithstanding, all the scientific researches and developments, its vastness is still unfathomable now. The outer space is a zone that is even more mysterious to us. Whatever knowledge we have at present, are mostly based on indirect evidences and basis. But, they have enlightened us to a great extent about the different facets of it.

So, what is the size of the universe, or to what extent or length the outer space continues? The answer to this is simple. We do not know – or we do know that it is endless. We are also unaware of its age or for who long it has been in existence. Apart from the ‘milky way’, there are uncountable numbers of other galaxies. They also contain the black holes and supernovas as well.

The Big Bang Theory

big bang theory

The ‘Big Bang Theory’ tries to raise the curtain on some of the issues, relating to the beginning of the universe. Researches point that the universe in fact, had an origin. The universe is believed to have been formed from ‘Singularity’ around 1.7 billion year ago. The singularity is believed to be the where all the matter and energy of the whole of universe were concentrated, which is somewhat akin to the dark hole. Its size was miniscule, may be a dot, and the density of it was so high that they defied the natural laws of physics of which we know of now. The singularity, which was infinitely hot in the beginning, exploded and then began to cool. With the cooling, it began to expand and ultimately attained the present state. And the cooling is believed to be still going on and so is the expansion. But it can expand itself up to the limit of its own matter – the matter and energy it contained originally. Scientists postulate that a state might come, when it would split. But, we never know for sure.

But, we have no idea what existed before the big bang and the explosion that we talk of, in fact, could be an expansion.

Then, what is there in the outer space? Our knowledge base can only grapple for an answer – unsuccessfully though. At this point, we look for something or somebody, who created all these. This is a point, where science and some divine power come face to face. But then, we can only look at the later for some answers.

This is a never ending debate. Do aliens really exist? Does any one have proof that aliens exist? If they do, why can’t we spot them with the help of our space instruments? Why don’t they fly down to our planet as we do to theirs? The questions keep boggling minds of kids and adults alike. But the truth remains that aliens do really exist. There are simply established facts and reported incidents, some even with videos, with proof that aliens really exist.

It is fascinating to watch human behavior that continues to be egocentric. Why else would they keep on debating the issue of proof that aliens exist, when they have hard core proof in their hands? Extra-terrestrials or aliens have been given a kind of artistic figure by Hollywood movies and we believe that if aliens exist, they would look like that. But question remains, what if aliens exist in any other form than the physical entity like ours? How do we then find proof that aliens exist?

The Universe is huge and to give proof that aliens exist would be no small a matter. Yet we have proof that aliens exist in real. A flying disc was seen once by pilots, crew members and many other people standing at Chicago O’Hare Airport in November 2006. This story was brought out on CNN and this is one undeniable proof that aliens exist.

There has been now official confirmation from the Government and NASA that they have proof that aliens exist. Their proof that aliens exist is not only based on historical events but the recent day findings as well. Take a look at the overwhelming evidence of UFO’s from past civilization on Earth. The Great Pyramid, NASCA lines and even Stone Hedges could be contributed to influences from the Aliens that might have visited our planet then.

There are still more proof that aliens exist. One such undeniable proof that aliens exist is the ancient elongated skulls that have been found amongst ancient monuments and also the prehistoric paintings and sculptures found in Egypt that portray people with unusually elongated heads and strange abdomens. Even the skull of Nefertiti the Goddess is strangely very elongated which means that her brains would be rather large than what we possess now.

The final and biggest proof that aliens exist is the collection of alien pictures from NASA’s own system and also footages of sound and movement that have recorded such unusual happenings. How long can we now deny the truth of proof that aliens exist?
