Different Types Of Habitable Zones

Planet Earth is the third planet from the Sun and the fifth largest of the planets of the Solar System. Earth’s surface is 71 percent water and is the only astronomical planet currently known where life exists. Earth is our home planet. Scientist and astronomers have studied our planet for Centuries and they have discovered much about our planet. Scientist have gained so much more knowledge of our Solar System in the last half-century after the NASA launched the first spacecraft and travel beyond Earth’s atmosphere has opened up to those who wish to explore. In the following paragraphs, we will discuss Earth and the

Throughout history humanity has been fascinated by the existence of extraterrestrial life. Today such ventures are in the development process and the discovery of life beyond our solar system, no matter how primitive, may soon become a huge(important?) scientific breakthrough. The three basic things that are required to consider a place even remotely habitable are water, a source of energy, and organic materials. Habitability also depends on other factors that must also be taken into consideration such as how close the planet is to its star (in the case of our solar system, the sun), how long the water and organic materials existed there, and the size and mass of the planet. One must not confuse habitable with inhabited. The term

The presence of a magnetic field means that there is some type of internal heat source along with a liquid ocean making the idea of habitability possible below the surface.

Until space industry can devise a transportation system faster than light-speed, humanity has no hope of ever exploring this planet. On more auspicious terms for discovering a habitable world, one does not need to look farther than our own solar system. Cassini, an orbiter of Saturn, discovered that one of its moons, dubbed as Enceladus, has liquid water beneath its icy crust. Furthermore, a rocky core at the bottom of the ocean confirms that the liquid water may have the essential minerals and nutrients to provide microbial organisms with a sustainable food

Preview Statement: The possibility of life on mars is an extravagant topic to look at. Before that, we must analyze Mars itself along with its conditions. First, we will talk about the ice caps located on Mars. Second, we will examine the water streaks on Mars. Third we will observe if the red planet is inhabitable for humans to conquer it.

Water on rocky planets can depend on many variables including the Carbon Oxygen ration of the host stars, which controls the content of water in the proto-planetary disk.

The discovery of water in the Orion Nebula will undoubtedly provide the basis for further study. More specifically, it will prompt scientists to search for water in other regions of space at different stages of star formation. Then, if water is present in each, it may suggest that "the oceans of Earth are older than even the planet that now contains them." 7

We now focus our attention on the formation of one particular planet, one that is so far unlike any other in the universe, Earth.

Habitable zones of a star are zones are where the planets orbiting the star have temperatures permitting the existence of water. Stable planets within these habitable zones are the ones that are most likely to have life o them. A stars habitable zone varies on the size and its luminosity. A star with a high-luminosity has a large habitable zone. A star with a low luminosity has a small habitable zone. Earth's habitable zone extends from the near orbit of Venus to the orbit of Mars.

Life has continually perplexed and fascinated individuals since the dawn of mankind. The subject’s complexity is so great even over the course of human existence only a minute fraction of its mysteries have been unraveled. A phenomenon which has always intrigued scientists is the origin of life on Earth, and in recent years significant advancements have been made in the understanding of this enigma. This essay will briefly outline two theories regarding life’s origin on Earth to further comprehend why an explanation for this phenomenon has been so difficult to reach.

What is life? This is a difficult question to answer, largely because life itself is not a simple concept. About four thousand five hundred million years ago the Earth collided with a planetoid the size of Mars. At this time, fragments orbiting the Earth formed the

our solar system, but they are unimportant compared to the nine major planets. In this paper I will discuss the planets and how they are each unique.

The distance from the host planet is another determinant of if life could possibly exist on a certain planet. This one is the possibly the most particular condition due to the relationship between location and temperature. The orbit cannot be located too close to the host star as the temperature would be too high and water would vaporize. In contrast, the orbit cannot be too far away from its host star as the temperature would be too low and the water would be frozen. For the planet, it is essential to have a circular and stable orbit around the host star. This is because if the orbit is stretched and unrestrained, it will generate extreme temperature fluctuations which will forbid the evolution of stable life. According to Refugees for Life in A Hostile Universe, the orbit has a range that the planet needs
