All we alone? It's a question that many hope to have answered
and some believe they already have the answer too.
Some scientists maintain that we will find alien life in the next 30 years.
If not sooner! There's nothing conclusive yet, but evidence
is mounting that we are not alone and that's our universe maybe teeming with life.
Number 10: Tiny Life On Meteorites. Earth has been hit by a number of meteorites
over the past 4 billion years of the many tons of cosmic dust and meteorites that hit
the earth on a daily basis. Three have been determined to have possibly
come in contact with life. When a thin slice of meteorite known as Nakhla
was viewed under a microscope fractures and tunnels that are similar to tunnels associated
with DNA were discovered on it. Though no DNA was found, tiny structures that
closely resemble fossilized nano bacteria, where nano bacteria are single cell organelles.
Much smaller than the accepted minimum size for a living organism.
From the examinations, It is estimated that as much as three fourths of organic material
found on this meteorite may not even be from earth.
A second meteorite, this one known as Shergotty, actually has many features that bear a striking
resemblance to the remnants of biofilm, the substance that allows microorganisms to stick
to each other. As well as communities of tiny organisms called
microbes. Number 9: The Wow Signal.
In 1977 Ohio state university picked up a strange signal from that big air telescope,
an observer tree that scan the sky for alien radio signals.
It had a fairly interesting way of measuring the strength of a radio signal.
It utilized numbers and letters, 0 was meaningless noise while zed meant that the telescope had
picked up a strong. On August 15th, astronomer Dr. Jerry R. Ehman
was receiving the most recent data from the big air.
It all seemed perfectly routine, until he reached the portion of what is now called
the wow signal. The telescope picked up a radio signal that
measured as “6 E Q U J 5” from an area of empty space.
Now that designation means nothing to you or I, but if it got the attention of an astronomer,
they'd want to know more. The signal was cited on the data sheet and
Ehman wrote the simple phrase, WOW. The 37 seconds of signal originated near the
Sagittarius constellation. The nearest star being over 220 light years
away. Many theories have been discussed as to what
caused the broadcast, But one thing that is certain is that it is interstellar in origin.
Number 8: The Black Night. Before we touch on the more irrefutable scientific
signs, we'll take a deeper look at some signs like this that are viewed with some skepticism,
but nonetheless are worth us explaining. The black Knight is a mysterious unidentified
satellite that was detected way back in 1899 by the Serbian inventor, Nikola Tesla, who
something intercepted signals from the unknown satellite.
The satellite is believed to be 13,000 years old and numerous others have since claimed
to have picked up similar signals before humans actually launched any satellites into space.
Yet, these aren't the only science behind the existence of this object.
When ground control picked up inexplicably signals during their pioneering mercury mission
that astronaut Gordon Cooper was part of, the evidence was made even more substantial.
When Mr. Cooper himself added that he saw green light belonging to the Black Night.
At the same time when they picked up the signals even more recently in 1998, during mission
STS 88 crew of the space shuttle orbiter Endevor photograph this unusual object in low earth
orbit. These images are often labelled as the most
definitive Proof of this satellite. Though, more careful analysis identifies this object
as space debris or possibly just a thermal blanket.
All of the evidence may seem rather unrelated based on fringe ideas and unusual observations,
but the aggregate body of evidence linked to the idea of this satellite just might have
been extra-terrestrial in origin. Number 7: NASA Coverups.
If anybody in the world currently knows whether alien life exists? It would most likely be
us government agencies, such as NASA. They would have incentives to hide information
from us to prevent enough people of society and conceal potential technologies.
What's unnerving is that there are strange signs to suggest that NASA has been concealing
information from the public. One of the most frequently cited relates to
NASA's cutting of live feeds during broadcast from the international space station.
It is believed that as soon as a UFO comes into view, the cameras stop streaming in order
to hide the evidence. Many believe it to be a blatantly obvious
and deliberate coverup of alien life, though, it could just be a coincidence or an honest
fault with the cameras. Other more disconcerting signs relate to actual
NASA astronauts, who have spoken about strange alien encounters.
One of the most frequently mentioned is linked to Dr. Edgar Mitchel, who was part of the
Apollo 14 space mission in 1971. During his two lunar missions, he spent 33
hours on the moon and explained how he was aware of several UFO visits during his career,
but each one had been covered up. He has also made other statements about famous
alien incidence, such as the Roswell crash of 1947, given that he's not the only astronaut
to expose such information, it would be unreasonable to dismiss his comments as uninformed speculation.
Number 6: Ancient Evidence. This might seem like another long shot, but
ask yourself this. If aliens have been visiting us, then why now?
Surely, they would have been around for hundreds or even thousands of years.
Well, some suggests this to be true, citing peculiar ancient hieroglyphs, as proof that
even generations before us knew of their existence. Just look at this famous hieroglyph panel
found in a stone slab, supporting the ceiling of the ancient .
It bears symbols resembling a helicopter spaceship and fighter jet planes.
These hieroglyphic panels were made 3 to 5,000 years ago when man had no idea about these
modern-day vehicles, whilst on the surface it seems astonishingly irrefutable proof of
alien life. There are perhaps better examples, because
studies have conquered that it is more likely the result of an accidental illusion, resulting
from overlapping hieroglyphics. Whilst there are other legitimately suspicious
examples. The internet is generally flooded with hoaxes.
Nonetheless, these aren't the only markings of aliens throughout time. Real old paintings
have pointed to the existence of extra-terrestrial life.
Just check out this example from a medieval tapestry in France, the painting depicts the
Virgin Mary in the foreground. Whilst in the background, there appears to
be a man looking up in or at an object that is strikingly similar to our modern-day perception
of a UFO. Do these confirm the presence of aliens over
time? or do they simply affirm our interest in the
subject of extra-terrestrial life? It's something that at the moment you'll have
to decide on for yourself. Number 5: Strange Radio Bursts.
Adding onto the evidence related to the wow signal. This one relates to a more substantial
body of proof. Since 2001 Telescopes around the world have
been picking up so-called fast radio bursts, that lasts just a few milliseconds and erupt
with about as much energy as the sun releases in a month.
10 have been detected so far and were determined to have originated 5.5 billion light years
away. The brevity of the bursts means that their
source has to be small, hundreds of kilometres across at the most.
So they can't be from ordinary stars, on top of that data analysts believe that there is
only a five in 10,000 chance of them being a coincidence as they seem to follow a mathematical
pattern, whereby the delay between the first and last wavelength is a multiple of 187.5.
This suggests that they may be communication attempts from extra-terrestrial civilizations.
Perhaps it's just the case that they're flagging us down with basic multiplication.
Number 4: Life On Mars. For more than a century people have speculated
about whether there is life on the red planet, that is Mars.
Thanks to NASA's cc that landed on the planet in 2012.
It's likely that soon we may know whether life was or is present on the planet.
So far, it has reported surprising spikes in methane gas, which is a suspicious sign
that alien life exists. Since on earth, most methane is produced as
a waste gas by living organisms. However, the presence of methane gas may also
be geological, but methane delivered in this method should linger in the atmosphere for
hundreds of years, to curiosity found that the gas had vanished within just a few weeks.
Number 3: Life Can Exist Anywhere. Even in deep space. Extremophiles are creatures
that exist in conditions that would kill most other kinds of life.
NASA recreated the conditions of deep space at their Ames research centre. To determine
if life could exist in the cold radiated depths, outside our atmosphere.
The researchers then expose two of the most abundant elements in the universe, carbon
and nitrogen, to the same radiation and vacuum that would be found in deep space.
The result created key components of DNA and RNA, the building blocks of life.
In addition, the Rosetta orbiter has confirmed that the ingredients for life are indeed found
elsewhere. This means that the same chemicals and molecules
that are allowed to form life on earth are present everywhere.
We know that there are exoplanets planets outside of our solar system, everywhere in
the galaxy. And now we know that these exoplanets have been exposed to the exact same compounds
that appeared on earth billions of years ago, and eventually became us.
Since the building blocks of life can form anywhere, life beyond our own rock is possible
and likely. Number 2: There Are Thousands Of Exoplanets.
In 2009 NASA launched the Kapitol satellite observatory, to look out into the farthest
reaches of space. As Kepler scans the void, it has discovered
and is still discovering a staggering number of exoplanets that may be habitable.
In other words, our galaxy alone is full of planets within the important habitable zone,
where life is likely to thrive. Now it appears that most stars have at least
one planet and a recent study has determined that at least 22% of sunlight stars are orbited
by Earth-like planets, that are not too close or far away from their parents’ star.
When we extrapolate this out to the 100 billion stars in the Milky Way galaxy, then we have
22 billion earth like planets in our galaxy alone.
That means there could potentially be trillions of earth like planets in the universe.
Just think about all the diversity of alien life that could exist!
Number 1: Life Could Be In Our Own Backyard. For example, as we know it, to survive we
need liquid water and heat and whilst we were searching far and wide for exoplanets that
may be habitable. The prospect for finding liquid water within our solar system outside
of earth may not be as unlikely as we first thought.
Apparently, there are entire oceans of liquid water beneath the crust of ice on Jupiter's
moon Europa, Ganymede and Satin’s moon Enceladus. In fact, our solar system is soaked in water
as is much of the greater galaxy. So much so that astronomers have NASA's astrophysics
division describe the Milky Way as a soggy place.
Even with water everywhere Europa is still the most likely site for alien.
This moon contains more water than all of Earth’s oceans combined.
Better yet, the gravitational forces of Jupiter assisting keeping the water of Europa liquid
and this massive ball of liquid is shielded from harmful radiation by its hard icy shell.
If we add in clay light materials known as phyllosilicates, that are usually associated
with organic materials, we can see why many scientists at NASA think it might be time
to go fishing for life on Europa. In light of the evidence, it seems like more
of a question of when? rather than if? we will find alien life.
So, what do you think? How long do you think it will be until we
find alien life? or alternatively. Do you refute the evidence?
