There Could Be Lava Tubes on the Moon, Large Enough for Whole Cities

Moon Lava Tube
Lava Tubes Beneath Lunar Surface – Bigger and More Stable

A research of networks of lava tubes that tend to wind beneath the lunar surface proposes that they could have been bigger and more stable than presumed earlier. The researchers sculpting the tunnels which are the remains of volcanic activity in the moon’s early stages are of the belief that they could possibly be up to around three miles wide thus raising the hope for subterranean bases.

The lava tubes which have been located in Iceland as well as Hawaii seem to be huge tunnels that have been carved out of the rock by the flowing lava. Geologists are of the opinion that they have been developed from streams of magma that had run dry, leaving channels through the solid rock.

Scientists are of the belief that the same structures are probably found beneath the lunar surface depending on small gravitational changes as well as images of cave openings gathered from lunar orbiters. If the lava tubes are found and seem to be stable they could offer shelter for a lasting lunar base.

Overcome Problems – Potential Hazards

This would help in overcoming the problems pertaining to potential hazards confronted by a base on the surface inclusive of the risk of meteorites as well as the increased solar radiation owing to the absence of protective atmosphere.

A group from Purdue University in Indiana had utilised computer demonstrating procedures in analysing how huge these tunnels could possibly grow. The circumstances on Earth would mean that the tubes tend to be limited to 30 metres across though the gravitational evidence recommends that on the moon they could be much larger. Utilising evaluations of rock density from the samples of moon rock, it was presumed that the width of the tubes would probably be thrice wider than their height.

The effects indicated that the stability is governed by the width of the tube, thickness of the roof together with the physical stress on the rock. In a paper published in journal Icarus, researchers had explained that if adequately deep, the lunar condition would probably generate fissures kilometres wide.

Lunar Base – Twice Commercial Base

It was informed that the theoretical maximum size of a lunar lava tube was based on various factors though with sufficient burial depth – 500 m together with an initial lithostatic stress state, the results portrayed that the lava tubes up to 3 miles – 5 km wide would be capable of staying structurally stable.

The estimates surpassed the earlier sizes that had been provided by the group during the 2015 conference which had recommended that tubes of 0.6 miles in diameter could be adequately steady to house permanent bases below the surface. Nasa scientists had earlier in the year calculated that there could be a possibility of returning to the surface of the moon in the next five to seven years at a total cost of about $10 billion.Spaceflight experts have debated in a series of papers, on the cost of building a lunar base which tend to be much less than anticipated and that there could be a substantial commercial value there.

They had mentioned that a lunar base can be twice a commercial mining base to enable the resources of the moon to be exploited. According to evidence, the moon could be a rich source of water ice, together with rare metals as well as a rare isotope of helium.

Gravity Waves On Venus Sparks Interest As Researchers Weigh In

Venus
Venus might be the closest look-alike to Earth we can get in our Solar system. It is likely dubbed as Earth’s sister planet due its similar size, mass, proximity to the Sun and composition. But that’s not why it has caught the eyes of scientists from all over the world. Huge waves have been spotted over the Venus atmosphere and what’s more mysterious is that these patches are stationary even though the clouds in the Venus atmosphere moves 100 meters per second.

What could be causing these unnatural patches? 

Since its discovery scientists and researchers have come forward with theories and the most plausible among them relates to the phenomenon widely observed on Earth and named as “Gravity waves”. These waves stretching over 6200 miles were created in the atmosphere just above the mountains by gravitational pull from the mountains as they flew over them. This would be a first time that these waves are observed on a planet.

What are Gravity waves? 

Gravity wave is an atmospheric phenomenon commonly seen on Earth surface that is laid with mountains. Roughly speaking they are formed when air ripples over rough and bumpy surfaces. The waves then move upwards and grow larger and larger in amplitude until they break just below the top of the clouds. It is speculated that the tall mountains over the Venus surface serve as a key factor in creating these giant gravity waves. Though the mechanism of the wave formation between Earth and Venus are quite different, the underlying principle remains intact. This feature which denotes atmospheric flow over the mountains should not be confused with “gravitation wave” which are time ripples in early universe.

These baffling spots were taken by Japanese Aerospace Exploration Agency’s Akatsuki Spacecraft as it entered the Venus orbit in late 2015. Researchers from Rikko University in Tokyo studied these waves and published their research in the Natural Geoscience Journal this year. These stationary waves lasted for quite some time in the Venus Atmosphere and were seen between December 7 and 11. Researchers added that the most interesting and unique feature of this phenomenon was it being stationary and remaining at that exact same geographical spot despite the super rotation of the Venus atmosphere at speeds more than 100 meters.

Planet Nine could be a 'Rogue World' Captured from another Solar System


ninth planet
Caltech/R. Hurt (IPAC)
What is there in the space? Is there really any evidence of solar system and its eight planets, as suggested by Science Text books? The world out there has always remained mysterious for us and we have believed everything what we were told by our teachers and text books. We know that many researches have been carried off till date by some renowned Astronauts but the most recent discovery involves the unveiling of the mystery behind the ninth planet of the solar system. Contemporary researches have heralded the ninth planet as a ‘fake planet’. The researches at New Mexico State University have concluded that it is no less than a rogue planet that was once counted as a part of our solar system.

It is an accepted fact that the ninth planet is no way a planet as it does not comprise of the qualities of a planet. Further researches have confirmed that this unidentified object is disturbing the orbits of icy objects. Facts also claim that the reason behind why the entire solar system is tilted is because of this rogue object.

The Scientists and Astronomers believes that the number of bodies and its orbits present there in the space as parts of solar system have been disturbed by the pull of this unidentified object. The Scientists have claimed that the Ninth Planet is approximately four times the size of our planet Earth and ten times its mass. From this we can understand that the force this unidentified planet can put in will definitely be able to disrupt the number of orbits.

This Planet Nine is said to have been relying on the gravitational pull it projects on the other objects. The Astronomers are worried that if this scenario persists then the doomsday for the Earth is very near.

Vesper and his mentor Paul Mason who is a professor of math and physical science ventured out for several encounters between our solar system and the rogue planet and have discovered that there are several planets or unidentified objects on the space and the ninth planet is also one of them. He said that these kind of rogue planets are abundant in number in the Galaxy. They have been suggested to even outnumber the stars that too by a huge difference and may also be a part of the dark matter in the galaxy as a resultant of circumbinary formation of planet. It has been concluded that if the number of such unidentified objects is so far reaching then the presence of this fake planet is acceptable.

However, there have been more than 40 encounters, but the rogue would finally come to an end after being captured by the solar system. Thus, the presence of this unidentified object in the Galaxy has turn out to be the matter of research for several Scientists and Astronomers which in near future will lead to an imperative discovery that will add a new dimension to that imaginative world and its objects.

UFO Hunters Claim to Have Found a MARBLE on Mars

MARBLE on Mars
 Scientists and Astronauts are still trying to figure out whether life can be possible on Mars or not as several instances have been found that suggests that life can exist on this fourth planet of the universe. Recent discoveries have propounded that instinct of a small marble is found on the ground of Mars. This new discovery has added new dimensions both veiling and unveiling new concepts and theories towards the research to locate life on the Mars.

The Mars Rover Curiosity have recently taken pictures that depicts the presence of a small unknown element lying amon
gst the known red dusty soil and coarse rocks. Some scientist claims it to be a marble, but the most acceptable justification is that it is none other than the Spherule present in Mars, which most obviously is understood to come into formation when the volcanoes discharge molten magma rock into the atmosphere.

On 20th December 2016 a black and white picture was captured that denotes the same ball like figure on the previous place, which suggest that it not has been removed from its place due the action of some weathering agent and also portrays that the previous picture that was taken was not wrong. However, some changes were found as the surrounding of that dark, small object was found to be covered with rocks and dust.
MARBLE on Mars_2

This current picture of Mars was initiated by Nasa’s Curiosity Rover, which has been trying to unfold the reality of this fourth planet discovering new foundations related to the surface of Mars since 2011 using highly advanced technologies and cameras.

The images captured till date claims this unidentified object as none other than a Spherule that is more likely to be present on Martian ground.

Several theories have come up related to this unknown object which should be considered before reaching to a conclusion that when molten magma rock was sprayed from the volcanoes due to utmost pressure from the interiority of the earth or from the meteors present in the atmosphere was delivered into the real world perhaps there long time measure was the formation of these spherules or marble like small and dark objects. Some other suggests that these Spherules were formed when the groundwater was ejaculated through porous rocks leading to a chemical reaction that would form these small balls precipitated from iron minerals.

MARBLE on Mars_3
Most favorably the scientists have addressed it as a Martian Spherule instead of considering it as a marble or life sustaining object. To this the question arises what is this Martian Spherule? The scientists have also found an answer to this as it can also be referred to as Blueberries because of the presence of a bluish tinge. This theory regarding Mars was discovered in 2004.

Many expeditions have been carried to reveal the truth behind the most ambiguous planet. But, still no concrete grounds have been prepared on which any conclusion can be forged. Just like the dilemma behind the truth of this censored object detected on Mars.

Could We Live Inside The Moon?

Moon

Lava Tubes – Offer Shelter for Long-Lasting Lunar Base


According to a study of networks of lava tubes that tend to twist beneath the lunar surface proposes that they could be much bigger and stable than otherwise presumed. As per researchers displaying the tunnels which has been left from volcanic activity during the moon’s early life, are of the belief that they could probably be up to three miles wide, which has raised the hope for underground bases.

The lava tubes that have been discovered in Iceland and Hawaii tend to be massive tunnels that have been engraved out of the rock due to flowing lava. Some of the geologists are of the opinion that they have been created from steams of magma that ran dry, leaving the channels through the solid rocks.

Scientist are certain that the same structures would probably be located under the lunar surface depending on minute gravitational changes as well as images of openings of caves collected from lunar orbiteers. Should the lava tubes found tend to be stable, they could offer shelter for long-lasting lunar base which would be beneficial in overcoming issues regarding potential hazards envisaged by a base on the surface, inclusive of the risk of meteorites together with the increased solar radiation owing to the lack of protective atmosphere.

Structurally Stable


Researchers from Purdue University in Indiana utilised computer modelling procedures in analysing how huge these tunnels could probably grow. The conditions, on Earth would mean that the tubes tend to be frequently limited to 30 metres across though the gravitational evidence recommends on the moon could be much larger.

With the use of estimates of rock density from moon rock samples, it was presumed that the width of the tubes could be trice the time wider than their height. The conclusion revealed that the stability was based on the width of the tube, the thickness of the roof as well as the physical stress on the rock.

The researchers had explained in a paper to be published in the journal Icarus that if adequately deep, the conditions of the lunar could probably generate caverns of kilometres wide. They further explained that `the theoretical maximum size of a lunar lava tube depends on various factors, though given sufficient burial depth (500 m) and an initial lithostatic stress state, the results indicate that the lava tubes up to 3 miles (5 km) wide could be capable of remaining structurally stable’.

Lunar Base – Twice a Commercial Mining Base


The evaluations surpasses the earlier sizes placed forward by the group during the 2015 conference which had indicated that the tubes 0.6 miles (1 km) in diameter would be adequately stable in housing permanent bases below the surfaces. NASA scientists, earlier in the year had calculated that there was a possibility of returning to the surface of the moon within the next five to seven years at a total cost of around $10 billion.

In sequences of paper the experts of spaceflight had debated the costs of building lunar bases would be much less than anticipated with a substantial commercial value there. They state that a lunar base could be twice a commercial mining base enabling the resources of the moon to be exploited. According to the evidence, it indicates that the moon could be a rich source of water ice, rare metals together with rare isotope of helium.

New Evidence Suggests 9th Planet Lurking at Edge of Solar System

9th Planet

New Evidence of Giant Icy Planet – Solar System


Recently the astronomers at the California Institute of Technology had revealed that they have found new evidence of a giant icy planet prowling in the darkness of our solar system way beyond the orbit of Pluto, known as `Planet Nine’. Their paper which had published in the Astronomical Journal assess that the mass of the planet as five to 10 times that of the Earth. However, the authors, astronomers Michael Brown and Konstantin Batygin had not noticed the planet directly.

On the contrary they had inferred its existence from the motion of lately learned about dwarfed planets as well as other small objects in the outer solar system. These small bodies seem to have orbits which look to be subjective to the gravity of hidden planet – a `massive perturber’. The astronomers propose that it could have been thrown into deep space long ago by gravitational force of Jupiter or Saturn.

Telescopic searches on at least two continents are on, for the object which on an average is 20 times beyond the eighth planet, Neptune. If the `Planet Nine seems to exist, it could be big around two to four times the diameter of the Earth and that would make it the fifth largest planet after Jupiter, Saturn, Uranus and Neptune.

New Horizons of NASA – Revealed World of Atmosphere/Weather….


However at such great expanses, it could reflect very little sunlight that it could have gone unnoticed by even the most powerful telescopes. On validation of its existence, the models of the solar system could be reconfigured. Pluto which was discovered in 1930 had spent three quarters of a century as the iconic ninth planet and then a decade ago, Pluto had received a debated demotion in large portion due to Brown.

As per his observation of the outer solar system, he had recognized several small worlds, some close to the size of Pluto and had urged the International Astronomical Union of reconsidering the definition of a planet. The IAU had elected to change the classification of Pluto to `dwarf planet’ a decision which was ridiculed constantly last summer when probe of New Horizons of NASA flew past Pluto, revealing a world with an atmosphere, weather together with a volatile as well as vigorously reworked surface.

Other Explanations for Observed Motion of Small Bodies in Solar System


Brown who tends to tweet under the handle @plutokiller and had written the book `How I Killed Pluto and Why It Had It Coming’, mentioned that now could be the time to rewrite the textbooks yet again’. Jim Green, director of planetary science of NASA, warned that there could be other explanations for the observed motion of the small bodies in the outer solar system.He referred the well-known statement from Car Sagan that `extraordinary claims need extraordinary evidence’.

He further added `The Sagan Rule applies – If it is there, find it, I challenge you. Somebody out there ought to find it’. He mentioned that he was excited regarding the new research and commented that `what an era we are in, where we’re discovering new things about our solar system that we never thought possible even a handful of years ago’.

Enceladus’s Underground Ocean That Could Host Life

Enceladus

Saturn’s Enceladus – Similar to Deep Oceans on Earth

An enormous breakthrough in the search for life on other planets has been revealed by scientists. Spacecraft of Nasa’s Cassini had provided scientist with the first clear evidence that moon of Saturn, Enceladus tends to exhibit signs of current day hydrothermal activity which is similar to that seen in the deep oceans on Earth. If the same is confirmed, it would make the moon Enceladus, the only known body in the solar system beside the Earth where hot water as well as rocks tend to interact underground.

 It is said that the activity would make the moon a much more attractive place for hunting microbial life. Astrobiologist consider the 314 mile wide Enceladus as one of the best bets of the solar for hosting life beyond the Earth. The satellite is said to be covered by an icy shell and is geologically active, as proved by the powerful geysers which tend to blast constantly from its south polar region. The clouds tend to contain substantial amount of water, which according to the scientists have originated from a subsurface ocean. Earlier research recommended that the ocean is in contact with the rocky mantle of Enceladus with possibility of all kinds of interesting chemical reactions.

No Sunlight Flowing in Underground Sea

The scientists discovered weird life form in hydrothermal vents on the ocean bottom, on Earth, where there seems to be no sunlight flowing through the underground sea of Enceladus. However, any microbes which tend to exist there could gain access to two different sources metabolism-supporting energy sources, molecular hydrogen and the heat provided by hydrothermal vents.

NASA states that the implications of this activity on a world besides our planet tend to open up exceptional scientific possibilities. These discoveries add to the possibility that Enceladus which comprise of a subsurface ocean, displaying remarkable geologic activity could contain an atmosphere which could be suitable for living organisms, according to John Grunsfeld astronaut and associate administrator of NASA’s Science Mission directorate in Washington.He further added that the location in our solar system where the extreme environments takes place in which life could exist, may bring us closer to answering queries to : `are we alone in the Universe’.

Hydrothermal Activity – Seawater Infiltrates/Reacts with Rocky Crust

Hydrothermal activity tends to take place when the seawater infiltrates and reacts with rocky crust and arises as a heated mineral laden solution, which is a natural event in the ocean on Earth. As per two science papers, the effects were the first clear indications that an icy moon could have same on-going active processes. The first paper published in the journal Nature relates to microscopic grains of rock that were noticed by Cassini in the Saturn system.

A four year extensive analysis of data from the spacecraft, laboratory experiments and computer simulations directed the researchers to the conclusion that the tiny grains probably formed when the hot water containing dissolved minerals from the moon’s rocky interior travelled upwards coming in contact with cooler water. According to the researchers, the subsurface sea of Enceladus contains dissolved sodium chloride like the Earth’s ocean but is full of sodium carbonate, also known as washing soda or soda ash. Study team members state that this alien water body is possibly similar to terrestrial soda lakes like the Mono Lake in California than it is to the Atlantic as well as Pacific oceans.

Hypothetical Planet Vulcan

Vulcan

Planet Vulcan Presumed to Be Orbiting Around the Sun


In the present model of the solar system, the planet Mercury seems to be the closest to the Sun. Planet Vulcan was the planned planet presumed to be orbiting around the Sun in the area between Mercury and Sun. Based on the calculation of Le Verrier, the proposal of planet was done to explain the peculiarities in the orbit of Mercury and the French mathematician, Le Verrier was the one who had predicted the existence of the planet Neptune by calculations to clarify the orbit of Uranus.

He assumed that the peculiarities in the orbit of Mercury could be owing to some unknown planet orbiting between the Sun and Mercury. Numerous investigators were involved in the study of the new planet Vulcan though no such planet seemed to be found. Peculiarities in orbit of Mercury had been clarified by the Theory of General Relativity of Albert Einstein. Besides Mercury, asteroid 2007 EB with a semi-major axis of 0.55 AU has the smallest known semi-major axis revolving around the Sun. Director of the Paris Observatory, Francois Arago, had suggested to the French mathematician Urbain Le Verrier, in 1840, to work on the topic of orbital motion of the planet Mercury around the Sun.

Purpose – Recommend a Model for Planet Mercury


The purpose of the study was to recommend a model for the planet Mercury based on the laws of motion and gravitation of Sir Isaac Newton.Towards 1843, Le Verrier had published his provisional theory on the topic that would be tested at the time of transit of Mercury across the face of the Sun in 1843. However his theory failed in matching the observation.

 He then published a thorough study of Mercury’s motion again. The consistency of the study meant that any deviation from prediction would be the result of some unknown factor and there would still be some discrepancy. During the motion of Mercury, its perihelion progresses by a small amount each orbit, technically known as perihelion precession. The value observed differs from the value predicted by Classical mechanics by around 43 arc seconds per century. Le Verrier assumed that the unwarranted precession could be described with the presence of a small planet within the orbit of Mercury, proposing the name `Vulcan’ for this object.

Astronomer Denies the Passage of any Planet over the Sun


Lescarbault, a country doctor at Orgeres, France had reported Le Verrier that he had seen an object which was a size of a planet cross the disc of the Sun on March 26, 1859. Lee Verrier had been to Orgeres and had interviewed the amateur astronomer regarding the unidentified planetary object. Lescarbault had estimated the duration of the transit as 1 hour, 17 minutes and 9 seconds.

He was completely convinced from the observation of Lescarbault and believed that he had seen the transit of an earlier unknown planet. He announced the discovery of Vulcan on January 2, 1860, at a meeting of the Academic des Sciences in Paris. Apparently not all accepted the discovery of Vulcan and renowned French astronomer, Emmanuel and Liais claimed that they had been studying the surface of the sun through a telescope which as powerful as the telescope of Lescarbault at the same time when reported by him. Liais has strongly denied the passage of any planet over the Sun during the time indicated.

Is there another mysterious Planet in Our Solar System?



In the infinite depths of space, all matter is in motion. As if moved by gears, all the planets of solar system orbit the sun, moving in their predictable elliptical paths. But something seems to be affecting the orbital path of Uranus. The seventh planet from the Sun. Some astronomers are convinced that there could be another celestial body near by. Is it possible that our solar system could have another planet?

In our solar system there are four like planets whose surfaces are solid Mercury, Venus, Earth and Mars. The four giant planets with fluid or gaseous surface (Jupiter, Saturn, Uranus and Neptune). Out of these Uranus the seventh planet from the sun, behaves in a strangest way. Uranus takes 84 years to orbit the sun; because of the 98’ degree tilt of its axis, twenty four years of day alternate with 24 years of Night and the poles receives more heat than its equator. Uranus orbital path is so irregular that it has been rich source of information for astronomers. Its striking deviation led to the discovery of Neptune in 1846 and Pluto in 1930.

But the unusual orbital path of Uranus can not simply be attributed to the influence of Neptune and Pluto and about 2% of its deviation cannot be explained. It seems Uranus is being attracted by and unknown celestial body of about the same mass as the planet itself- which is 14 times greater than the mass of the earth. In other words there may be another planet in addition to the known planets.

If a mysterious celestial body exists how do we explain the fact that the most powerful telescopes have not yet detected it? The answer is simple. If there is another planet we would have to look for it at the furthest reaches of our solar system at least four thousand million kilometers beyond Pluto. This distance makes the observation difficult. The only certain thing about it is, it is not a giant planet. If it is comparable to Saturn or Uranus; Astronomers would have found that.

Since research has produced no evidence; scientists are working on other hypotheses. Photo graphs mad in stellar observatory on the island of Hawaii between 1992 and 1994 indicates at least six celestial bodies at a distance of several thousand million kilometers. If their existence is conformed these stars may prove that another Planet could never have formed beyond Neptune and Pluto because there is too little matter at that distance, and its concentration is too low; But for some astronomers, such as Clyde Tom Bough- who discovered Pluto in 1930- there is a reason enough to believe in the existence of a Mysterious planet.

IS THE EARTH SLOWING DOWN ?!!!!!!!!!!!!!!!!!!!!!!

Do you know, The earth is slowing down? The rotational speed of the earth is slowing down. This was first found by the famous scientist,mathematician,astronomer Edmond Halley. A comet is bearing his own name as Comet Halley, to honor him for his remarkable job in astronomy.

The earths speed of rotation was slow down but the rate at which it takes place is very very small and it can not be accurately measured in a small interval of time. In 100 years or more a day or night will be two milliseconds longer. Now our earth takes 24hours to take one complete rotation on its own axis but about 400 million years before it was about 400days long.


Here we gave to remember again the moon is revolving around the earth more slowly and moves away from the earth few centimeters per year. The interaction of moon and earth are the result of the above interrelated phenomena.

we know gravitational pull of the moon and sun cause tides. Apart from these two the centrifugal force of the earth is also a reason for it. The height of the tides depends upon the shape of the coast, depth of the ocean and the shape of the Ocean bed.

The movement of water masses and tides makes some friction on the earth crest which absorbs some energy of the earth which works like a brake and slow down the earth's rotation.

As some time in future our planet will slowed its rotation and it will lose its own satellite moon. Further, after 4 thousand million years the earth will stop its rotation on its own axis which will result in dividing into two halves extreme hot and extreme cold region.

Is the Moon the Earths own sibling?!

Is the Moon  the Earths own sibling?!

No other planet in the solar system possesses such a large satellite like moon. The first person to develop a theory about the moon was the scientist George Darwin son of the most famous Charles Darwin. He hold the view that the moon and the earth had once been very closer together than now.  He thought that they had been hold together as a single planet revolving at a high speed around its own axis with a time taking less than two hours per rotation.

By that time the earth was molten and with high temperature.  As the speed of rotation was high the earth bulged at the equator.  The centrifugal force gradually caused a drop of terrestrial matter to detach itself and fly out into the space.  This piece of the earth becomes moon, which continues to revolve around the earth as the satellite.

 As a proof for his theory, Darwin shows the Pacific ocean which is shaped like a bowl. What he says  is Pacific ocean is a scar left behind when the moon detached away. For most of the years the Astronomers  though that Darwin's theory was more or less correct, but however later realise that the separation of moon from the earth could not have taken place in the way he described.


Then another theory was framed.  The moon also was a small independent planet in the solar system when the solar system was formed however on one of its orbits it came a bit closer to the earth and it was influenced by the earth's gravitational pull and forced to follow the earth's orbit.


In 1960, a new hypothesis  Accreation theory was  framed according to this, when the solar system was young numerous planetary embryos, disintegrated near the earth.  The pull of the earth caused the embryo to form a ring around the earth.  Since the particles attracted one another and they began to cluster together finally forming the moon.


None of these theories was satisfactory  to the scientists. The chemical composition of the moons surface differ from the earths crust. On the moons surface there is no alkali metal such as sodium, potassium etc but heat resistant oxides of aluminium and calcium are abundant which proved Darwin theory was wrong and the rock analysis further revealed that moon contains only 10 percent of Iron compared to th30percent of Iron content  of the earth.  Hence this proved  capture theory and growth  theory are wrong.


The origin of moon still present mystery we know that our planet and moon are of the same age. Further we know that our own satellite functions as a climatic regulator for our earth.
