(By Rudolf OgooOkonkwo)--While some of us are sure of the number of gates to
heaven and the kind of visa needed to get in, some scientists are scratching
their heads trying to figure out how to locate the 9th planet. Those who have
mastered the layouts of heaven, including the postal code of their mansions,
are waiting for death to come and take them there. Well, not really. Most of
them are not in a hurry to make the journey. It is, however, slightly different
for scientists. For scientists, they are willing and are working to send spacecraft
on a journey of over 2.8 billion kilometers in search of the 9th planet.
When most of us were in school, the 9th planet was
Pluto. It used to stand shoulder to shoulder with the likes of Venus and
Saturn. In 1992, questions were raised about its status as a planet, following
the discovery of several other objects of its size within the area called the
Kuiper belt. In 2005, an object called Eris was discovered. It has mass that is
27% more than Pluto. So in 2006, Pluto was demoted from a planet to a mere
dwarf planet for failing to clear the objects around its orbit. On July 14,
2015, the New Horizons spacecraft tapping the gravity of Jupiter flew by Pluto
accurately measuring it and providing conclusive proof that it wasn’t a planet.
Scientists have since found out that there are thousands
of such objects found beyond Neptune. Some of the objects orbit the sun at 140
billion miles away. Some, like Sedna, orbit the sun every 19, 000 years. It
means that if the last time it came around was the year Jesus was born, the
next time it will come around will be the year 21,016. Definitely, nobody who
will live on this earth then will remember that anyone who lived in our time
ever existed, including Albert Einstein and Bill Gates. Their accomplishment
would have become so miniscule then that encyclopedia of the time will be very
generous to give them one paragraph or a sentence. They will be like the great
people who lived on this earth some 20,000 years ago. Yeah, there were great
people then though we have no idea who they were.
Pluto's demotion left a lot of holes in our
understanding of how the planetary system works. Every model of our solar
system suggests that there is a 9th planet. The gravitational pull and the
orbit structure around our sun clearly indicated that something is pulling
something from a distance and is keeping everything in place. Scientists could
accept by faith that the thing pulling is the 9th planet. But they are not.
They are looking for it with bigger and bigger telescopes. They are also
sending space probes to travel billions of miles to find it. Looking at
gravitational pull around the area beyond Neptune, Prof. Brown and other
scientists at Caltech concluded that there is an unknown source of gravity at
play.
Several hypotheses have been thrown out. Using computer
models, some theories have been established. One of the most fascinating one is
the possibility that 4.5 billion years ago, our sun stole a planet from another
solar system. This planet is the 9th planet that is orbiting billions of miles
away from our sun.
If that is true, it makes that 9th planet one that is
exoplanet- that is a planet in our system that came from another planetary
system, which makes it an exciting possibility. Finding the 9th planet and
possibly exploring it will give us insight into what is happening in places far
deep in the universe that our technological prowess may not take us to in the
next 100 years.
Such prospect is so exciting that our scientists are
already on the case. The first sign that it would be possible to go there and
find the 9th planet came with the successful arrival of Juno to the orbits of
Jupiter on July 4th after a five-year journey that started on August 5, 2011.
At the cost of $1.1 billion, Juno will study the
magnetic and gravitational structure of Jupiter as well as the composition of
the largest planet in our sun. Jupiter is 1000 times the size of the earth and
is the planet that spins the fastest. For the last 150 years, a storm called
the Great Red Spot has been raging in Jupiter. The temperature near the Jovian
core of Jupiter is estimated to be over 20,000 Celsius, which is three times
hotter than the surface of the sun.
Jupiter is the third shiniest object in space after the
moon and Venus. Long before Jesus came, ancient Romans named it after the king
of Roman gods, Jupiter. Jupiter has 67 moons out of which four, discovered by
Galileo Galilee in 1610, are very prominent: Europa, Lo, Ganymede and Calisto.
Jupiter completes an orbit in 11.96 years but it rotates around its axis in
less than 10 hours.
Nobody knows what is inside Jupiter. Some believe that
Jupiter is the storage site of all the gasses that came out when the universe
was formed. Juno will study the surface of Jupiter and help scientists
understand how the planets came together 4.5 billion years ago.
The theories around Jupiter are interesting. It is
believed to be the planet that kicked Uranus and Neptune to the outskirt of our
planetary system. Some have theorized that it was Jupiter that hurled the
asteroids that landed on earth and delivered water to earth upon which life
started. In the last 40 years, eight spacecraft have visited Jupiter but there
are still a lot that we do not know because cloud of gasses covers the surface.
In the course of the mission, Juno will go round Jupiter
37 times. At some point it will be as close as 2,600 miles. It is currently
orbiting Jupiter at one orbit every 53 days. On October 23, it will change
course and move into an orbit that will loop around Jupiter every 14 days. All
these are happening at a distance of 2.8 billion kilometers from Earth.
The scientists’ next target is to send another
spacecraft to Jupiter’s moon Europa. The craft will fly by Europa. On June of
2022, a European craft called Juice will leave the earth and in 2030 arrive at
Jupiter to study the moons and fly over the largest called Ganymede. These
moons are covered in ice and believed to have water buried in them. Scientists
believe that there are forms of life in these moons. It is the reason they are
making sure that Juno does not crash into any of them. They do not want the
unsterilized Juno to transfer Earth microbes that followed it to space and
contaminate these moons.
If the writer of the book of Revelation were to do so
today, he will definitely update it with knowledge from the pictures Juno and
other spacecraft have been sending back to us from space. His allegory on the
struggle between good and evil as represented by the beast with seven heads and
a great dragon would have been less bombastic and vague, and would have
reflected the order we now know exists up in the heavens. The locusts wearing a
human face and hair and having lion’s teeth would have borrowed a few gadgets
from Juno for a long journey across space and time where stars are collapsing
and rivers are turning into blood.
Nevertheless, in February 2018, Juno will commit
suicide. It will do so by plunging into the magnetic field laden surface of
Jupiter for its final scientific mission. It will do so, just for us. It will
not be painful for we take comfort in knowing that our scientists are already
working on more superior spacecraft as replacement. These are spacecraft that
will be sent to watch out for silence in heaven as they do greater exploration
for us in a continuing chase for heaven.
