the closest planet to the sun and based on research, it consist of iron and
certain inorganic mineral matters. The up-to-date discovery about the planet contiguous
to the sun is that its magnetosphere is approximately 4 billion years old.
mission, to study the planet Mercury, came to an unexpected standstill when the
spacecraft finally ran out of fuel and crashed. Nonetheless, data from the mission will continue
to provide new information about Mercury for some time to come. As this was not
presumed scientifically to occur.
Based on routine scientific research, Scientists have known that Mercury had
a feeble magnetosphere for a while. Although it is not as strong as the
Earth’s, it is believed to be the only other body in the innermost solar system
to have a magnetosphere. The magnetic field is created by molten iron within
the revolving core of the planet. This thus point to the theory engulfing the
hotness of mercury, second to the sun. It’s proof that Mercury is the only planet in the solar system other
than Earth that possesses a global magnetic field generated by a
shifting molten core of liquid iron, researchers say.
during one of Messengers closest passes to Mercury. The spacecraft was within
10 miles from the planet when the data was developed and seemingly integrated.
This boons a challenge for those hopeful to “terraform” Mars. Mars is understood to have had a magnetosphere
at one time, but it was lost at some point about 3 billion years ago. That coarsely
corresponds to the time when Mars is thought to have lost much of its water and
Whereas it is conceivable to present more water and possibly microbial and
plant life to the planet, there is no known way to reboot a magnetosphere.
The Earth’s magnetosphere verifiably blocks most of the solar wind and
solar radiation. Without it the Earth would be much warmer, dryer and level of
radiation would be much higher. Although Mercury also has a magnetosphere, its
proximity to the sun makes it much too warm to support life, as we know it.
Mercury’s magnetosphere could, nevertheless, benefit to explain how the
planet has managed to retain small amounts of ice, despite the heat. In totaling,
to providing data on Mercury’s magnetosphere, the messenger mission showed
that the planet has ice at its
poles as well as buried deep inside some of its craters.
Being adjacent to the sun also makes Mercury more of a target for major
solar system components like asteroids and meteors. In addition to its heavily
cratered surface, Mercury’s black color comes from a rain of cosmic dust, left
by asteroids orbiting the sun over billions of years according to a report published in March.
Messenger’s data on rocks close to Mercury’s surface showed that the planets
magnetic field is 3.7 to 3.9 billion years old. That means that the
magnetosphere formed in the early history of the planet. Like Earth, Mercury is
thought to be roughly 4.5 billion years old.
“The mission was in the beginning prearranged to last for one year; no one
expected it to go for four. In a statement released by Catherine Johnson, a University of
British Columbia planetary scientist. She said the science from these current topical
clarifications is really interesting and what we’ve learned about the magnetic
field is just the first part of it. The chief author of the study on Mercury’s magnetosphere
“If we didn’t accurately come out with these recent explanations and remarks,
we would never have known how Mercury’s magnetic field evolved over time. It’s
just been coming up to tell us its story,” said Johnson, also a current novel scientist at
the Planetary Science college.
