Why Do Intelligent Life Exist On Planets Other Than Earth

Improved Essays
Throughout time, scientists have researched whether intelligent life exists on planets other than Earth. Scientists have sent many different telescopes and devices into space to try and capture life on other planets. They have been trying to find life on Mercury, Venus, Mars, Jupiter, Saturn, Pluto, Neptune, and Uranus. Scientists think Mars has the best chance of sustaining life. Scientists have done research as to if each planet in the Milky Way Galaxy can sustain life. What they found was that every single planet in the Milky Way Galaxy, besides Earth, cannot sustain life. All of the planets they have done research on have come back failing to show signs of life. Intelligent life does not exist outside of Earth because other planets are …show more content…
Mars is the fourth planet from the sun in our solar system and even though it resembles Earth so much, it is only about half its size. The surface of mars is very dusty, but the ground is frozen solid (Life On Mars). Mars has the North and South Pole just like Earth. The North and South Pole on Mars both have ice caps made from water and carbon dioxide. Most of the water on Mars forms permafrost which coats the planet’s surface (Exploring Life’s Mysteries). Scientists have recently found liquid water on Mars, but it is mars atmosphere that creates a problem for intelligent life to live on the planet. Mars atmosphere severely lacks oxygen. Mars’ atmosphere contains ninety-five percent carbon dioxide, three percent nitrogen, and one and six-tenths percent argon (Exploring Life’s Mysteries). It has significantly lower pressure than Earth has. These factors would greatly impact any intelligent life form attempting to survive on Mars. Mars’ temperature ranges from negative 225 degrees Fahrenheit to seventy degrees Fahrenheit (Life On Mars). The atmosphere of Mars itself keeps intelligent life incapable of living on …show more content…
The atmosphere on Jupiter is very thick and the whole planet is mostly made of gas (Exploring Life’s Mysteries). The biggest factor that keeps intelligent life from being able to live on Jupiter is how the planet transfers heat. Jupiter absorbs heat from the sun then outputs twice as much. Jupiter’s temperature ranges from negative 190 Fahrenheit to forty degrees Fahrenheit (Exploring Life’s Mysteries). Jupiter has barely any gravity compared to Earth, which would be a big change if intelligent life would try to live there. The average temperature of the clouds on Jupiter is around negative 224 degrees Fahrenheit. Jupiter’s atmosphere is made up of mostly hydrogen and a small amount of helium (Exploring Life’s Mysteries). Considering the atmosphere and temperature intelligent life would never be able to survive on

    With an average temperature of 864 degrees Fahrenheit, it is about fifteen times hotter than Earth. Not only that, but the harsh condition of its atmosphere which is ninety-two that of Earth, and full of sulfuric acid and carbon dioxide, make human life virtually impossible. However, some researchers believe some sort of life may be somehow possible. The surface of Venus is extremely dry, according to radar maps, but there is a possibility of small sulfur lakes and rivers so shallow, they have been missed. If there was life on Venus, it would definitely not be humans.…

    The atmosphere of Venus is composed of mainly of carbon dioxide and some nitrogen, though there are trace amounts of other compounds and elements within it's atmosphere such as carbon monoxide, argon, neon, and helium. This combination of elements and compounds makes the atmospheric pressure of Venus more than ninety times heavier than the Earth's. The clouds upon Venus reflect so much of the sun's light that is impossible for human's to view it's surface. This is due to the high amounts of sulphuric acid clouds in it's atmosphere. Along with that, Venus is one of the hottest planets within our solar system, despite the fact that it is much farther from the sun than Mercury.…

    Astronomy in Yosemite The Sun The sun is a star located at the center of the universe, and without it, there would be no life on Earth. It is the most important source of energy for humans as it provides us light, heat, and more. It can reach surface temperatures of about 5,276 degrees Celsius, and 10,340 degrees Fahrenheit. The composition of the Sun changes slowly as hydrogen is converted into helium in its core; however, it is currently made up of around 70% hydrogen, 28% helium, and less than 2% of other metals. From satellite images of the sun in space, it appears to be a great, red, fiery ball of energy.…

    Stars don 't spend much of their life in this stage. They only spend about one billion years in this stage, because helium burns quickly. As the helium runs out and the fusion stops, the star expands one more time. Until, it then shrinks again, and the helium flares up, causing the outer layers of the star to drift off in massive clouds of gas and dust. Those massive clouds are known as planetary nebulae.…

    Actually, the fact that Earth has life at all already makes it unique! Earth is the only known planet that can support life (for now at least). Astronomers have been studying deep space looking for another planet with any life at all, but the technology isn’t advanced enough to know whether or not they have found one in their many candidates! Although there are people who disagree, there is evidence that shows there must be another planet like Earth in our universe, or at least another planet with life. One of the reasons that this Earth-like planet is hard to find is the time delay between what we see from Earth and when things actually happen in deep space.…

    The theory tells tries to show that the moon and earth was together when they past through a black hole. When going through the black hole the moon and earth separated as they are today. The only flaw in that theory is that it wouldn't explain why the moon orbits the earth. The theory that is probably the most trustworthy is the Giant Impact Hypothesis. The Giant Impact Hypothesis is that when the earth was still forming around 4.5 billion years ago the moon hit the earth, at least now it is called the moon before this mars sized planetoids was called Theia.…
