Are We Alone? : Discovering Life on Other Planets Habitable Zone and The Drake Equation
A habitable zone, which is also known as the Goldilocks Zone, is basically a region where there is a probability in finding the extraterrestrial life. The finding is based on the temperature and the pressure of a certain planetary-mass objects. When the temperature is between 273K and 373K, there will be presence of water that can support the extraterrestrial life to live in that zone. Tau Ceti which is 12 light years from Earth lies in this region. The habitable zone in the universe can be presented in the Figure 1 as shown below.

Figure 1: The Habitable Zone
The probability is then presented in an equation which is called Drake Equation. It is used to estimate the number of active, communicative civilizations in Milky Way, not far beyond that. It was formulated in the year 1961 by Frank Drake and is generally accepted by the scientific society. The Drake Equation is represented as shown below in Figure 1.

Figure 1: Explanation of the Drake Equation
The application of the equation could be useful to estimate the possibility of intelligent life to be on certain exoplanets. Since 1992, 506 exoplanets had been discovered to have extraterrestrial life. The discoveries about the Habitable Zone proves us that this zone can support intelligent ET civilizations as the planets and the stars are heated in this region at an optimum temperature for living things to live on. With the high possibility of having water in this area, it gives faith for extraterrestrial life to really exist on Tau Ceti e which is the fourth exoplanet from Tau

In the second part we learned the Period- Semi- Major Axis Relationship, The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit. The third law captures the relationship between the distance of planets from the Sun, and their orbital periods. We find out the Period and the semi major…

There is a subsection of exoplanets called “Goldilocks Planets”, coined by Neil de Grasse Tyson. A “Goldilocks Planet” is an exoplanet that is within its host stars habitable zone. The habitable zone is a band around the star where it is “just right”, water is in a liquid form, which makes…

The article The Martian Chroniclers a new era of planetary exploration by Burkhard Bilger discusses Earth and Mars known as the “Goldilocks Planets,” this is because Earth and Mars both have the perfect environment for life to be sustained. I was first observed that Mars had evidence that it could sustain life in 1877, by the astronomer Giovanni Schiaparelli. Schiaparelli drew a map of mars as an “earthly paradise.” This was because he observed that the planet had what appeared to be continents and water channels on the surface. Although, it was discovered that Mars has less water contents then earth’s driest desert. Nevertheless, because of Mar’s atmosphere and geological environment Mars has the possibly that it can sustain life. NASA has sent many space crafts to explore what is on Mars the first was the Mariner 9 then, Viking 1 and Viking 2, the…

A group of astronomers is suggesting that the planet called Kepler-62f may be habitable. The distant planet is approximately 1,200 light-years away from Earth towards the Lyra constellation. Kepler-62f is unique due to it being 40 percent larger than Earth. With that and it's planetary range, scientists believe it may possess oceans, and maybe even life. NASA discovered the planet back in 2013 but at the time, did not reveal any information about its atmosphere. Suddenly, they know that Kepler-62f ha a warm atmosphere. Warm enough to have surface water. If this is true, it's possible many other exoplanets surrounding Earth could bear these life-giving qualities.…

To humans, exploring and needing to know what is beyond the horizon is part of our nature. In July 2015, we watched the spacecraft, New Horizons, reach Pluto after nine years and three billion miles. As a result, we learned that Pluto is not just a giant ball of ice, but has a molten core just like Earth, and may have the right ingredients to possibly hold life. Although this sparked a possibility of life outside of earth; we should start exploring at our oceans first.…

What does a planet need to have in order to support life? Earth is unique in our solar system because it is the only planet that is supporting life. Some scientists go so far as to say that the Earth is a “perfect planet” because it has features that are the perfect environment for living organisms; these features include our atmosphere, water, and a single moon. Earth is also in a place in our solar system where the Sun gives off the right amount of energy to drive the life. The distance from the Earth to the Sun determines how much of that heat we receive. If it weren’t for our ozone layer and Earth’s magnetic field, harmful rays would penetrate our surface and life would be exterminated. Everything the Earth has to offer us is balanced perfectly to keep life continuous.…
