The reason the moon appears to change color is due to the reflection of visible light coming from the sun. Because the moon has no light of its own it relies on the reflected light of the sun to create moonlight and change color. The reflection of light coming from the sun cause’s the moon to appear as if it is changing color because as the sun’s light rays travel through
the earth’s atmosphere the moon catches light from the sun and reflects it down to earth. As the moon reflects the sun’s light rays down to earth, those rays of light travel through the earth’s atmosphere in the form of different wavelengths which then produce different colors of visible light. For example when the moon is low in the sky and close to the earth’s horizon, light from the sun has to pass through more of the earth’s atmosphere in comparison to when the moon is high in the sky or positioned directly overhead. When this happens, air molecules filter out short wavelengths of visible light such as green, blue, and purple and scatter’s them throughout the earth’s atmosphere. When the moon is high in the sky...
...nd violet wavelengths are the shortest, and violet is the least visible to the human eye. These wavelengths are scattered throughout the day and caused by a redirection of the light-waves direction due to gas molecules in the atmosphere (Mc Knight, p. 84). When the sun is setting towards the end of the day there are few blue wavelengths left and we see orange and red which are dominant and the longest wavelengths of visible light to the human eye. At the bottom of the photo (closest to the setting sun) red and orange are the dominant visible colors with the occasional blue and almost violet. If our eyes could not see orange and red our sunsets would be a dark blue or black.
more surrounding objects, and the relative distance between the Earth and the Moon appears to get closer.
Especially as there is practically no evidence left on the Earth from when it was initially created. Most of the evidence, long gone due to the Earths extremely rocky start though constant meteoric attacks, different life inhabitants, etc. The fact that the moon is essentially a fingerprint of the Earth holds many answers to the mystery and allows science to further go in depth to what things were like for planet Earth billions of years ago. It has been found that the creation of the moon itself was caused by high impact into the planet, the moon has also been determined to be moving further and further away from the Earth which slows down the Earth’s rotation, and lastly that because of the moon the Earth has stable seasons which prevents the planet from either being a big burning wreck which is inhabitable to humanity, or a giant ice ball which is also inhabitable to humanity. All in all, as discovered in the film “Origins, fourteen billion years of cosmic evolution: Earth is Born” the moon is a necessary part of our planet and one of the many keys to unlocking its many
The surface of the moon is scarred with millions of impact craters. There is no atmosphere on the moon to help protect it from bombardment from potential impactors (most objects from space burn up in the Earth's atmosphere). Also, there is no erosion (wind or water) and little geologic activity to wear away these craters, so they remain unchanged until another new impact changes it. These craters range in size up to many hundreds of kilometers, but the most enormous craters have been flooded by lava, and only parts of the outline are visible. The total area of the moon is 37 930 000 square kilometers.
The center of the Lake can appear indigo, as blue light is absorbed further, leaving more visible violet light
bright and shaded. The main colors are colors that can be found mainly in natüre alone and
Color is a product of many different things. We physically see color by the light hitting the retina and being absorbed by the rods and cones. Colors are distinguished by sorting them into categories. These could include tint, shade, tone, chroma, value, or hue. It could also be determined by whether a color is primary, secondary, intermediate, or complementary. The illusion of different colors can be created by the colors around a color or placing bits of color very close together as in a television. Afterimages create the opposite of colors. All color is a product of light. Without light, we would only be able to see in black and white (The World Book Encyclopedia p 818, 819, 822, 823).
Thus, when the white light from the sun hits a raindrop the light is dispersed as it enters (like in the prism). The different colors undergo refraction and reflection due to the change of index of refraction between the water and the air.
...lieve that millions of years ago, a piece of rock as big as Mars hit the Earth, and the collision blasted a huge amount of rock into space, and the shattered pieces of rock went into orbit around the Earth. Over millions of years, the rocks clumped together to form the moon, and now it is not the pieces of rock that orbit the Earth, but the moon itself. Scientists, Native Americans, and many other people have their theories of how the moon became, but none have been proven. Scientists have studied the moon for many years, and have proven many theories, but not this one.
For many centuries scientientist have been puzzled by the common illusion that the rising of the moon at the horizon looks bigger than it looks later on in the day and for the past nine centuries they have know that angular subtense of the moon's horizontal (azimuth) diameter always measures about 0.52 degrees at an earthly observation point no matter where the moon is in the sky. For more than 100 years, various scientists interested in visual perception (a specialty within psychology) have conducted experiments on the moon illusion . And they said the distance theory have suggested two different reasons why the horizon moon would look farther away than the zenith moon. The most popular version of the theory appeals to the ancient idea of a "sky dome illusion"
How and why does a blood moon occur? That was my first question I thought to myself when we looked into the night sky at the big red orb. Some other questions that popped into my head when we stared at the moon were; why is the moon all of a sudden red, how do scientist calculate when the next lunar eclipse will come again and what’s the difference between a solar and lunar eclipse. All these questions resonated in my thoughts and by my astronomy knowledge and research I am now able to answer all those questions.
There are five basic theories in the formation of our moon. The first is the "fission theory" which states that the moon was once a part of earth, but separated a long time ago. The second theory is called the "capture theory". This theory is says that the moon formed somewhere else, and was "captured" by earths gravitational pull. The third theory is called the "condensation theory" this theory states that the moon and earth were condemned together from the original nebula that formed our solar system. The fourth theory called the "Colliding Planetesimals Theory" states that the interaction between the earth orbiting the sun, and the sun orbiting planetesimals, which are large Astroid like rocks, led to the breakup and formation of our moon from the debris of these planetesimals. The fifth and final theory is called ...
Most objects are not pure color, so that they reflect a mixture of different types of light. There are three basic colors that can be mixed in various proportions to make all other colors. When dealing with light, we mix the three primary colors, but the primary colors for light mixing of red, green and blue.
Numerous places and religions have suggested a reasoning around the Northern Lights to give some sort of explanation. However, it could be that people just needed another entity that guided their beliefs in some way. As time went on scientists clarified what the Northern Lights really are, “The Northern Lights are actually the result of collisions between gaseous particles in the Earth's atmosphere with charged particles released from the sun's atmosphere.” (Northern Lights Center). This interaction between the sun and Earth cause a display of many different colors. They include shades of red, yellow, green, blue, and violet. However, pale green and pink are the most common colors seen. The Northern Lights and sunspot activity has been around since about the 1880’s, but people did not fully know of the reason for these lights until the 1950’s. The different gases in our atmosphere are the reason for the colors produce in the sky. Oxygen molecules cause the yellowish-green color that is seen a lot, while nitrogen produces a blue or purplish-red color. “The temperature above the surface of the sun is millions of degrees Celsius. At this temperature, collisions between gas molecules are frequent and explosive. Free electrons and protons are thrown from the sun's atmosphere by the
