The Moon - Introduction
Its hard to imagine the history of Earth without our Moon. For as long as man walked this Earth, the Moon served as "lesser light for the night" and faithful time-piece. The phases of the Moon were used to help guide the Harvest, or help determine the time of the river floods.
How our Moon came to existence is still under speculation. There are several possible scenarios:
Fission Theory - the Earth spinning so fast during early formation that a piece broke off forming the Moon
Capture Theory - the Moon formed elsewhere passed close to Earth and was captured
Co-Creation Theory - the Earth and Moon formed and evolved together
Collisional Ejection Theory - a large piece impacted the Earth and broke off pieces of the

The light areas are lunar highlands. The dark features, called maria, are impact basins that were filled with dark lava between 4 and 2.5 billion years ago.
After this time of volcanism, the Moon cooled down, and has since been nearly unchanged, except for a steady rain of "hits" by meteorites and comets. The Moon's surface is charcoal gray and sandy, with much fine soil. This powdery blanket is called the lunar regolith, a term for mechanically produced debris layers on planetary surfaces. The regolith is thin, ranging from about 2 meters on the youngest maria to perhaps 20 meters on the oldest surfaces in the highlands.
Unlike Earth, the Moon does not have moving crustal plates or active volcanoes. However, seismometers planted by the Apollo astronauts in the 1970s have recorded small quakes at depths of several hundred kilometers. The quakes are probably triggered by tides resulting from Earth's gravitational pull. Small eruptions of gas from some craters, such as Aristarchus, have also been reported. Local magnetic areas have been detected around craters, but the Moon does not have a magnetic field resembling Earth's.
A surprising discovery from the tracking of the Lunar Orbiter spacecraft in the 1960s revealed strong areas of high gravitational acceleration located over the circular maria. These mass concentrations (mas-cons) may be caused by layers of denser, basaltic lavas that fill the mare basins.
In 1998, the Lunar
The moon is by far the biggest and most easily recognizable object in earth’s atmosphere that can be perceived by the naked eye on a cloudless night. It is hypothesized that it came into existence nearly 4.5 billion years ago, from residual debris after a planetary body collided with earth. Although, considered the runner-up to the sun as the second brightest object in the sky, its illumination is deceitful, insomuch as the moon is not a source of light, but instead reflects the sun’s illumination from the half of the moon that is in direct alignment with the sun at that time. More readily identified as a satellite of the earth rather than as a planet itself or even a star, it has a diameter a quarter of the size of earth’s size and it
spinning so fast that a part of Earth flew off and created the moon. This theory has some major
Have you ever considered that the moon may not be exactly what it seems to be? Science says that the moon was a result of the Earth colliding with another planet, causing a rocky mass to break free from the earth and be pulled into orbit by the force of gravity. Conspiracy theorists have considered the possibility that the moon may be something more than just a rocky mass orbiting the earth. A theory that has been created regarding our moon is called The Hollow Moon Theory. This theory tries to prove that the moon may just be a cover or a protective layer around an alien's UFO. It may be hard for some to go against scientific research, but there is a possibility that something other than a collision is responsible for the formation of our moon.
craters. The smaller moons of Saturn, are mostly rock and ice, and are heavily cratered.
“Even if scientists wanted to make something like a Moon rock by, say, bombarding an Earth rock with high energy atomic nuclei, they couldn 't” (Phillips). In addition, Phillip C. Plait agrees with Tony Phillips and comes to the same conclusions. For example he states there are no stars in the picture because, “The stars are too faint to be seen in the images” (Plait 159). However, unlike Tony Phillips, Plait explains the scientific reasons in depth. He claims astronauts have survived the incredibly high temperature of the Moon due to simple date counting. He explains, “Moon spins on its axis once every 27 days … [which] means … two weeks of sunlight and two weeks of darkness… the surface doesn’t heat up the instant the sunlight touches it…It takes days for the lunar surface to get to its high temperature…” (Plait 166).
The astronauts found on the regolith that the highlands have aluminum in its rocks and the regolith in the maria contains iron and magnesium which happens to be a major component of basalt. There was two main types of rocks found on the Apollo 11 site, basalts and breccias. The first type of rock was basalts were are solidified from molten lava. Basalts are made up of pyroxene and plagioclase which was formed by two chemically different magma sources and are dark gray which is why the Moon contains dark areas. The second type of rock are breccias which is composed of fragments of older rocks by the heat and pressure of meteorites. These samples from the regolith and maria provided facts that the maria was covered in lava flows and in the highlands provided how earth was like like 4.5 billion years ago. Apollo 12 mission contained basalts with low amounts of titanium and Apollo 17 mission had a sample of “orange soil,” which consists of small orange glass beads. The beads are glass because they cooled rapidly with no crystals insider and all had different colors from titanium. Scientists conducted on basalts and pyroclastic glass which showed that they formed when the interior of the Moon partially
There are many different theories about how the moon was formed. People believe different things. I believe one is more reliable than all the others. I think the Big impact theory is the most trustworthy. The Big Impact theory has many different pieces of evidence behind it. The other ones i could barely find any.
In 1975, two scientists by the name of Dr. William K. Hartmann and Dr. Donald R. Davis, came up with a groundbreaking new theory on how the moon was created. Their theory stated “At the time Earth formed 4.5 billion years ago, other smaller planetary bodies were also growing. One of these hit earth late in Earth 's growth process, blowing out rocky debris. A fraction of that debris went into orbit around the Earth and aggregated into the moon” (Hartmann & Herres 1). This theory is known as the Giant Impact Theory and is the accepted theory in the scientific community of how the moon was created. Even though this theory is accepted by most, there are still some people who don’t hold this theory to be true. I agree with Davis and Hartmann’s Giant Impact Theory that a great collision occurred and created the moon. The Giant Impact Theory is supported by the lack of iron on the moon, the moon rocks from the Apollo missions, and its acceptance in the scientific community.
When the moon was created scientist had discover that there was similar materials that was the same as the earth, but some of it was a little different. The first reason is the earth has a atmosphere, while the moon has no atmosphere on itself. The second reason is the earth has shorter days than the moon because earth is 24 hours, while the moon is equal to 27 earth days. The third reason is the minimum temperature, the earth temperature is -126 degrees Fahrenheit, which is warmer, the moon temperature is -387 degrees Fahrenheit. This is why the moon and the earth had some differences to each
The planet Mercury, named after the Roman God of Thievery, has an incredible grey surface, littered with craters. Whilst it may lack an environment, pulverised dust roams across its massive stretches of grey fields, and rocky cavities form the land of mercury, resulting in a lack of any possibility of life, unfortunately. Images taken from powerful telescopes give the resemblance of this planet to Earth's own moon, through the grey colours and rocky formations. From Muggle Space Probes, we know that there have not been any signs of clouds, dust storms, or any form of a source of water, further connecting it to the moon. The Caloris Basin, the largest crater on the planet, stretches for 1,550 kilometres across Mercury's fields of grey;
There are a lot of moon but the four main ones or biggest ones are Io, Callisto, Europa, and Ganymede. Io is very hot and has a lot of volcanos and lava. All of the volcanos cause the surface of Io to be covered in sulfur which is ash from the volcanoes. Jupiter's gravitational pull is so strong that it causes Io’s solid surface to to rise and drop, like a wave, from 300-100 feet at a time! Europa’s surface is the opposite. It has ice and is might be all water. It is even thought to have twice as much water as earth. Europa is thought to actually have life under the ice but no one has ever been there to see. Callisto is very heavily cratered. It is thought to be one of the first of Jupiter's moons. It is just like our moon but bigger. There isn't much of anything out of the ordinary about it. Ganymede is very crazy because it has its own gravitational pull unlike moons. It almost fell for a dwarf planet if it didn't orbit Jupiter. This makes it the largest moon in our solar system.
The planned path of the Slider will allow the team to observe the elemental makeup of various aspects of the moon, including the surface, interior, and gases comprising the cryovolcano plume. The mass spectrometer will detect the amount of these life-supporting elements present in each of these areas.
Earth rocks are very abundant in these minerals and other minerals that thrive in the high temperatures. They are almost completely deprived of these types of elements. Moon Rocks don?t. Moon Rocks also contain small ball like pieces of glass. The main theory on how this happened is by Moon dust being heated to extremely high temperatures along with other minerals. The hot dust would form a small glass piece, and the other minerals would form the rest of the rock. Earth rocks do not have this feature. .
The evidence that has been concluded in support of the giant-impact hypothesis is that the Earth contains a lot more molecules that can exist as vapour, for instance water, than the Moon does [1]. This evidence suggests that the heat generated from the collision that occurred billions of years ago turned these molecules into vapour, which could therefore not coalesce as the other molecules, which cannot exist as vapour, did to form the Moon, so the Moon has less of them [1]. Additionally, more evidence is that the
The night of observing, the Moon was in the waxing gibbous phase. The Moon was formed when it collided with Earth as a planetesimal and now it is an object that orbits Earth. The distance from Earth to the Moon is 238,855 miles away and is about 4.5 billion years old. (How) That night at 8:15 pm the telescope was places so we could see were the Moon was illuminated and where it was dark. On the left side of the Moon their were some darker spots, were greyish in color, compared to the reset of the Moon. Even though it was partly cloudy with slight wind that night we could see the craters on the Moon clearly. Through the telescope I saw craters with a typical bowel shape and others with more complex. Another type of crater I saw was
