4. Each of the planets within our solar system possess characteristics that make them unique, despite forming from notably “universal” elements. These differences can be attributed to the conditions they were under during their formation, and a study of their composition and atmospheres can help us explore their past. The composition and relative “thickness” or density of a planet’s atmosphere is dependent on gravitational strength and relative temperature. Larger planets are capable of stronger gravitational forces, resulting in the ability to retain gases like hydrogen and oxygen. Smaller planets are unable to carryout this retention, leading to outgassing of these elements early during their formation. Temperature also influences the ability …show more content…
For example, bacteria on earth are responsible for regulation of nitrogen levels. Evolution of photosynthetic activity during the primordial existence of earth can be attributed to the CO2 and O2 balance that we rely on today. Highly volatile “rare” gases were most likely dissipated to space during the formation of terrestrial planets, suggested by the fact that these rare gases exist in higher abundances in different isotopic forms in the Sun’s high temperature and gravitational pull than they do in Earth’s atmosphere. Observation of differences between Venus and Earth can demonstrate how critical a balance between temperature and density are for atmospheric composition and how we can use these observations to form hypotheses about a planet’s formation. Venus is very similar in size to Earth, but it’s incredibly high temperatures lead to a loss of H2 and O2, causing an oxidative atmosphere that doesn’t allow for the presence of water and other organic material. This could suggest that Venus formed at a position much closer to the sun. In contrast, Earth’s extensive oceans result from a methane rich, reducing atmosphere that preserved the elements essential to
6. The atmosphere of early earth primarily may have consisted of a reducing atmosphere thick with water vapor, along with nitrogen and its oxides, carbon dioxide, methane, ammonia, hydrogen, and hydrogen sulfide.
Although this did not seem correct since the theory was not able to prove why different stars contained different amounts of elements. Kean then transitions into planets, explaining that the planet Jupiter is a failed star making it contain certain elements that other planets did not contain. Towards the end, the author discusses scientist Clair Patterson’s research on finding how old Earth was using meteors, uranium decay, and lead. Ch.
When the sun was a young star, the leftover material formed what would be planetary disks. These are accounted by all the planets in the solar system. Venus was made into the second planet from the sun. Over the next billion years the planet formed. There
Did you know that Venus can be described as a volcano? Earth and Mercury are the two closest neighbors to Venus. Venus is one of the five planets that have existed for so long that date of discovery is unknown. Venus was named after the Roman god of love. Venus is very interesting because of its composition, ancient history, and research.
In December of 1978, an orbiter entered Venus’ orbit. This orbiter was called “The Pioneer Venus Orbiter” one of the two spacecraft which launched Venus to collect data. Along with the orbiter, the “Pioneer Venus Multiprobe” was also sent to Venus where used it had four different probes to collect data through the surface, yet only one probe made it and transmitted the data back. The objective of this project was to create a map of Venus’ surface.
Venus is the next terrestrial planet and it is only slightly smaller than Earth and is the second planet from the sun. One day on Venus is longer than a year due to its slow rotation. It takes 243 Earth days to complete one rotation and rotates in the opposite direction of all other planets except Uranus, and is roughly 67 million miles from the sun. Venus much like Mercury has no moons to speak of and is often referred to as the morning star and the evening star as it is also one of the 5 planets visible to the naked eye and it is the 3rd brightest object in our sky besides the moon and sun. It is the same with the discovery of mercury it has been visible but nobody knew what it was until Copernicus unveiled
Surprisingly the name “Venus” given to those statuettes has no connection with the Roman Goddess Venus but since they carry such feminine traces and resemblance, they are considered a representation of a female goddess by some.
During the Upper Paleolithic era artists created a wide range of small sculptures. These sculptures were made from various materials, including ivory, bone, clay, and even stone. They represented humans, as well as animals; they even combined them at times. Most of the sculptures from this time show a high level of skill. From this time, there were two very influential sculptures, The Venus of Willendorf and the Venus of Laussel. This paper will discuss both sculptures, in detail, as well as, compare and contrast them.
Old-Earth View Old-Earth creation hold that the earth is ancient “4.55 billion years” (Ross, Whitmore, Gollmer, and Faulkner, 2015, The Heavens & the Earth. Dubuque, IA: Kendall Hunt Publishing Company.) The Nebular Hypothesis supports that “the Earth is billions of years old. In 1798, Laplace, a distinguished French mathematician and astronomer, first suggested that the planets were created from the atmosphere of the sun, which, because of its heat, originally extended beyond the orbit of the most distant planet.
Hypothesis: Venus once had a moon, which came too close and caused a chain of events that altered the course of Venus' history.
There are two main factors that contribute to the varying degree of brightness coming from Venus. The first has to do with how much of the planets surface is being illumined by the sun. When Venus gets near it superior conjunction, when the Sun is perfectly inline and in between Venus and Earth, more of the planet is being illuminated thus more light is reflecting off the surface and back to Earth. So when Venus is nearing its inferior conjunction it tends to look brighter. However; the distance of Venus from Earth is even more important. When Venus is nearing its inferior conjunction, when Venus is perfectly inline between the Earth and Sun, it looks brighter because less light dissipates coming back to Earth. So when Venus is near either
We now focus our attention on the formation of one particular planet, one that is so far unlike any other in the universe, Earth.
In our solar system, planets and dwarf planets have many similarities that had scientists bewildered about weather it was a planet or a dwarf planet. But now, after years of studying these planets and now with superior technology, we have found the vital difference with our eight planets and five main dwarf planets. The main difference is that our planets have a clear path around the sun, while dwarf planets, still orbit the sun, have debris and space junk in their paths. Other differences still lie within the (dwarf) planets themselves. Adding on, the five main dwarf planets in our solar system are very similar, but still have extra bits and pieces that make them unique. These dwarf planets include Pluto, Makemake, Ceres, Eris, and Haumea.
The center part inside the painting, The Birth of Venus show there was a young lady who was the goddess of love – Venus. She was standing above a big shell. Obviously, the Venus was a young lady and she was about 16-20 years old. Venus doesn’t has any cloth on her body, she was naked.
Life is an amazing and seemingly rare phenomenon. With the materials necessary and the process that had to take place in a certain order, at certain times, it really is a wonder that we are here. What is even more impressive is that we have managed to evolve past single-celled organisms, and into intelligent life forms. With our increased intelligence, there coincides an increased number of questions that need answers. Does other life exist? What do planets need to support life? Where do we go from here? Throughout this paper, I hope to answer these questions, or at least provide some evidence as to what we know so far. The focus will mainly be on the different types of habitable zones, what special resources and properties are required for a potentially habitable planet within one of these zones, and what this all means.
