Jupiter’s Movements Might Have Brought Water to Earth and Other Rocky Planets

Jupiter protects us from things hurling at us from outer space.

New scientific studies show that gas giants such as Jupiter were vital in transportation of water to the Earth and other terrae planets in the early solar system. Simulations showed that due to the large mass of these planets the water rich material was pulled inward and scientists realized that prerequisites for life were created. This finding is incongruent with earlier theories that expected Earth’s water from carbonaceous asteroids most of which is…. According to the study, large gaseous planets in any solar system could also help transport water towards the star’s vicinity, giving new life to the Hunt for Earth-like planets in the universe.

Jupiter played many roles in the early evolution of the solar system. Thus, on the one hand, the giant planet eliminated threats to the formation of the Earth as it swept all the hazardous material beyond the Inner planets. On the other hand, materials were also being sent towards the Inner planets and so the Hydrogen dense Asteroids, Planetesimals or the young Planetary embryos often impacted the young Terran Planets.

Now, scientists propose that Jupiter and other gas giants may have provided something essential to rocky planets: Water.

These massive planets may have steered water-rich debris in the outer region of the solar system straight into the rocky planets. A new study shows that this water delivery was not random, essential for life as it is recognized today. However, for any other planetary systems where there was a gas giant in the outer region it would automatically send water rich material to the inner rocky planets.

When gas giants formed, they could throw material further in, while initially being dangerous for the objects, the material was hydrogen rich and got locked in earth’s crust and mantle. This material was later used to combining with oxygen to produce water.

“During formation, they eject this huge pile of planetesimals somewhere in the solar system, and some crash into the terrestrial planets,” said Sean Raymond, an astronomer from the University of Bordeaux, France, who led a research published in the journal Icarus. In this case, Raymond modeled how gas giants affected the early SOLAR system and determined that water-bearing material is always smacked into rocky planets, which can retain the liquid.

Water is a condition for life on our planet and, as such, any planet that can support it will remain at the top of any list looking for other forms of life in the universe. For the past 30 years scientists have working hard to find out where water came from with opinion stating that water-rich asteroids from space were responsible.

This early solar system featured the following; collision events and intersecting orbits directed asteroids to rocky planets Besides the gravitational pull from the fourth planet. “Indeed, it is quite an interesting story and core to learn regarding the formation of habitable planets,” said Conel Alexander, an astrochemist at Carnegie’s Department of Terrestrial Magnetism who investigates primitive meteorites from these asteroids.

Approximately 4. Around 5 billion years ago the Sun formed, and from this process a raw material in the form of a gas cloud birthed the planets. This gas remained for millions of years forming the dynamics of the planets and their rocky constituents. Because the temperatures spiraled up towards the middle, hydrogen – which is a building block for water – was able to remain frozen as ice in far off other regions of the solar system.

Initially, it seemed that Earth was going to end up being a sterile rock devoid of any water. So, what changed?

A ridiculously simple concept

Some of the recent models showing the evolution of our solar system show that the giant planets shifted considerably before migrating to where they are today. Neptune and Uranus are likely to have formed closer to the Sun and then have moved out and even have ‘changed places’. This change, call the Nice model, probably initiated the Late Heavy Bombardment, a time of increased icy body impacts, 600 million years after the formation of the solar system.

Saturn and Jupiter may travelled a more sinuous path, they have osculated through the young asteroid belt at the inner part of the solar system then changed direction and went back again to the outer parts. It was fun as they travelled and they shot asteroids towards the earth. This idea is reflected in the so-called model of Grand Tack, which Raymond assisted in creating in 2008.

It was around that time that Raymond was developing an interest in how Jupiter delivered water to Earth but he was set back slightly by a small programming blunder. It wasn’t however until almost 10 years later that, in the form of a post-doctoral researcher Andre Izidoro, the task was accomplished.

“It took Izidoro half an hour to find a bug that I had had for years,” Kumar quoted Raymond and further he laughed and mentioned, “I was glad that he found it so we could begin with the project. ”

The new model predicts that when a gas giant is forming and catching materials on its disk, its gravitation later on affects other protoplanets. Nebular gas continues to exert a drag on the debris; this in turn determines the direction of movement of some of the debris towards the inner planets. Some of this material was accreted into the asteroid belt and these asteroids brought water which content is carbon and that equal to that of the present day Earth.

Raymond goes further by asserting that the asteroids are where carbon was abundant where the compounds were spread across a region roughly between 5 and 20 times the Earth’s distance from the Sun. “I think it must have covered the whole solar system”, he replied.

But Alexander, who focuses on carbon-bearing asteroids, believes that the area was much smaller, and the majority of the formed right beyond the orbit of the largest planet Jupiter. Nevertheless, he acknowledges that according to the model put forward by Raymond the water-rich material got to the Earth, saying that “this hypothesis is quite reasonable, as far as I am concerned.

“This is the best way to get these volatiles into the terrestrial planet-forming region,” Alexander added.

This is true, but the given model is not without its mysteries: it does not explain, for instance, why so little of the early solar system’s mass has survived to the present day. “That is a part that has to be linked,” said Raymond.

However, he says that the model offers an understanding of several things, for example, why the water composition of Earth is of outer belt asteroids than that of inner belt asteroids.

“That is a mind-bogglingly obvious thing that just happens when Jupiter and Saturn mature,” Raymond said.

Hunting water-rich worlds

Prior to Raymond’s model, people thought that giant outer planets’ irregular motion bringing water to inner solar system, making Earth not turn into a waterless planet. If this were the case then we would be in trouble of other planetary systems that had large planets in close proximity to where they started.

Raymond’s model though points that under natural course, any gas giant forming would indeed tend to spread water rich material inward. Raymond went on to learn that while gaseous planets of Jupiter’s size were most efficient in it, even gaseous planets of lesser size could set the ball rolling. This discovery is good news for astronomers seeking water-laden exoplanets in the universe beyond our celestial neighborhood.

In our own solar system, the model suggests that ice from the outer regions was delivered to Earth in three phases: first, during the formation of Jupiter ; second during the formation of Saturn; third when Uranus and the Neptune moved closer to the Sun before being pushed away by Jupiter and Saturn.

“The coolest thing is that it basically says that for any exo-solar system with giant planets and terrestrial planets, those giant planets would deliver water inward to the terrestrial planets,” said David O’Brien, a researcher at the Planetary Science Institute who works on planet formation and evolution of the early solar systems. “This means that there is a lot that can be done on researching these habitable planets. ”

Unfortunately for us, we do not have many of the similar systems to compare it with at the moment. The majority of the discovered exoplanets have been detected through NASA’s Kepler mission; it excels in identifying planets with orbits less than that of Earth and struggles to identify the ‘gas giants’ in distant orbits. It ought to be noted that smaller rocky planets are also more challenging to detect. It does not mean that such systems are nonexistent — only that scientists have not come across them yet.

If such systems exist, Raymond’s research indicates that the rocky planets that are found in them should be full of what we call the liquid of life. “If there are such things as terrestrial planets and giant planets out there, those giant planets most likely gave the terrestrial planets some water,” O’Brien said.
