Why Is Nasa's Possible Exoplanets?

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

Exoplanets are any sort of planet that inherently orbits a star. In this context, the sun cannot be recognized as a star that will be orbited around. Exoplanets vary in size that can be smaller than Earth or even larger than planets such as Jupiter and Saturn. Exoplanets are capable of orbiting their star at various distances. The exoplanet is dependent to certain areas that navigates the distance between it and the star that it is orbiting. Orbiting at the perfect distance depicts the exoplanet in the star’s “habitable zone.” Precisely meaning that the temperature is just right that allows water to be in its liquid form and the exoplanet might be capable of supporting life.

In the article called “Another Earth” by Alice Savage and David Wiece started with the sharing of the theory that life outside of Earth could exist. The author’s son thinks that it’s possible for other living being to exist and live on other planets, but the author had this theory as just a theory until the moment when scientist found a lot of planets that can potentially have live life on them. After that, he starts to share his memories about what people thought about life outside of Earth back in the 70’s. He shares this idea that to find a planet we have to look at stars. He talks about two methods of how we can find a planet looking at a star. Planets have their gravitational pull and when they are moving around a star we can see them

For numerous years NASA has been finding many answers about the universe. Imagine gaining more knowledge and understanding of the universe at a faster rate, where humans could go out in space to colonize other planets. Human civilization could live for more years after the sun has died. For this to happen it will cost a lot of funds. Although funding is costly, NASA will find new energy resources, a greater understanding of space, and will prevent human extinction.

have yet been detected on any of the nearly 2,000 scientifically confirmed exoplanets. So we

it was discovered that there are other planets like Earth out there that are able to accommodate life forms like our planet. And it is highly unlikely that we are the only living things out there in the big universe

The centuries old quest maybe as old as NASA has been started for other words like our earth has been rejuvenated by the intense surrounding the discovery of hundreds of planets. The kepler mission, which is one of NASA’s best discovery missions it is specifically designed to survey our region of the Milky Way galaxy to discover hundreds of Earth-size and smaller planets in or near a habitable zone.

Currently, there is only one planet we know of to host life, and that is our home planet Earth. The question remains as to what is exactly needed for a planet to be considered habitable, but scientists have developed a handful of criteria to help distinguish what planets could be “just right” for life. The ongoing search for possible habitable planets has produced many remarkable findings but nothing quite as extraordinary as the discovery of the system Trappist-1. According to nasa.gov, it is the first known system of seven Earth-size planets around a single star, and it meets the criteria to possibly sustain life (“NASA Telescope Reveals” p.1). This discovery poses a likely answer to the question “are we alone” and drives our search for finding out more about what is out there.

For many centuries astronomers have asked themselves a simple three worded question “Are we alone?” This simple question has become a controversy all around the globe. Why? Because we want to be able to communicate with other life forms (aliens). However, in order for us to find life in another planet we first have to find planets that have the possibility to support life, nevertheless that question wasn’t answerable until 2009. In 2009 NASA launched a telescope that was going to search for planets. This telescope was known as the Kepler Space Telescope who’s job was to detect earth like planets orbiting a star.

An exoplanet can be defined as a planet that orbits a star outside the solar system. One of the many exoplanets that could possibly be habitable in the near future are far away. For example, Kepler-186 is around 500 light years aways to put that in perspective that is around 5,878,625,373,183.607731 Miles away. That is why we know so little about these planets that could support life on them.

The main searches for exoplanets are being done by space missions. The Kepler space mission is finding the most exoplanets, however there are many other space missions like Gaia, MOST, CoRoT, and SWEEPS, that are finding exoplanets in habitable zones. There are also ground missions including the Anglo Australian Planet Search and HARPS which is done in Geneva. This graph shows all the exoplanets found that are less than 10Me or 1.5Re mapped on the habitable zone. The sizes of the circles indicate the radius of the planet, which has been estimated, if not

Earth-sized planets are every common, and early data suggest that such planets are also common in habitable zones. It seems reasonable to suppose that a significant fraction of all stars have at least one habitable planet, which means there should be many billions of habitable planets in our galaxy. The flife presents more difficulty, because we do not yet have any reliable way to estimate the fraction of habitable planets on which life actually arose. However the rapid appearance of life on Earth and the fact that laboratory experiments suggest possible ways in which life could have arisen both make it seem that life should be likely on habitable worlds. in that case, we might expect most or all habitable planets to also have life, making the fraction of flife close to

To begin with, there is more than one sun out there in space, and a sun can contain about one million planets in space. Scientists have discovered about one thousand planets orbiting distant stars. They have much more to discover! There is a big possibility that in one of those planets life could exist. Another big clue that scientist have discovered is that there are many galaxies in space and we live in one. The galaxy that Earth is located at is called the Milky Way Galaxy. A galaxy can contain many planets just like our galaxy can contains over billions of planets.

A new and exciting discovery was made on the date of: April, 17 2014 that would change our view of the universe we live in. The discovery of Planet Kepler-186f is a big deal to scientists. What's the big deal about just another planet? Well this planet is different! According to scientists Kepler-186f is almost the exact size of Earth, and it is in part of its star system where liquid water could exist on the planet's surface. Leaving us to wonder, could there be life on another planet? Some scientists are sure that there could be life on this planet. Planet Kepler-186f is approximately 490 light-years away. In my opinion this discovery really shows us that there is so much left to be discovered! I'm sure the exploration

Humans have longed to believe in extrasolar planets, as surely there have to be planets elsewhere in the universe. Claims of supposedly discovered extrasolar planets can be dated back to 1855 when Captain S. W. Jacobs from the Madras observatory, claimed that he had discovered a planet orbiting a binary system (Jacobs 1855), all the way up until 1991 when a team of astronomers announced then retracted the alleged discovery of an extrasolar planet around a pulsar star (Lyne and Bailes 1992). Planets are extremely hard to detect as they are a very faint light source and the light from its parent star is much brighter and essentially blocks out light from a planet (Winters 1996). It was not until 1992 when the first exoplanets were confirmed
