Exoplanet Research Paper

You are not able to see planets with a naked eye so Nasa uses telescopes to see in higher depth . There are different kind of telescopes that are used to look outside the Solar System some of the names are X-ray and gamma-ray telescopes and Kepler .The telescopes detect distant of planets by measuring the minute dimming of a star as an orbiting planet passes between it and the earth.Nasa has not been that useful of finding that many exoplanets because they are still trying to find out have much light they need to let in to make sure they can see the exoplanets. Nasa said that they will not stop looking until they find as many as they can.

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

The astronomers studied the elliptical galaxy M87, located 53 million light-years from Earth in the constellation Virgo. They examined a unique series of images taken with the Hubble Space Telescope over the course of three months in 2006. They quickly found what they were looking for.

Candidates must follow up observations and analyses to show that they are actual planets . However , Kepler-452b was identified by the Kepler space telescope , and its discovery was announced by NASA on 23 July 2015 .`` We`ve been able to fully automate our process of identifying planet candidates , which means we can finally assess every transit signal in the entire Kepler dataset quickly and uniformly`` said Jeff Coughlin, Kepler scientist at the SETI Institute in Mountain View , California , who led the analysis of a new candidate catalog . `` This gives astronomers a statistically sound population of planet candidates to accurately determine the number of small , possibly rocky planets like Earth in our Milky Way Galaxy `` . Scientists now are producing the last catalog based on the original Kepler mission`s four year data set

NASA tends to get all the credit for major space findings however, it's the European Southern Observatory that is making headlines now. According to scientists, Proxima Centauri, is a red dwarf star. This red dwarf is smaller and colder than our sun. Yet, it's warm enough to sustain life on other planets. The life on this new exoplanet

The Kepler Mission began in March 7th, 2009. The goal of The Kepler Mission is to “survey a portion of our region of the Milky Way galaxy to discover dozens of Earth-size planets in or near the habitable zone” (NASA). This is accomplished by using a photometer to look for transits, then transferring the data to earth through the Deep Space Network. Once a planet has been detected, a number of different methods can be used to determine the planet’s size, composition and habitability. In order to understand The Kepler Mission completely, one must understand the structure of Kepler, the search methods used, how the data is interpreted, and the implications of the results.

Many scientists and space enthusiasts awaiting news about a second Earth were answered when NASA announced the results its phoenix-like telescope Kepler, had found. The exoplanet that created so much excitement has a size and age reminiscent of Earth’s, and, critically, even exists in the Goldilocks zone of its Sun-like star, ensuring its neither freezing nor burning away any possibility of complex life.

Discovered on February the 3rd, 2009, we find a gaseous planet that is in the Constellation Monoceros in the Milky Way Galaxy. Formed

Over the last two decades, the study of exoplanetary systems has become a very active field that will grow continuously in the coming years as technology has made it possible to actually observe the Cosmos beyond the Solar System. The simple definition of an exoplanet, also called extrasolar planet, is any planetary body that orbits a star outside of our solar system (Encyclopedia Britannica). In a Scientific manner, an official definition of exoplanets may be at this point unjustified since the situation is still evolving and that any definitive definition is likely to be too rigid to adapt to new discoveries (Schnieder et al. 2011). Prior to the 1990’s, it was not possible to detect planets with certainty beyond our Solar System due to lack of technology

A star and its planets form out of a collapsing cloud of dust and gas within a larger cloud called a nebula. As gravity pulls material in the collapsing cloud closer together, the centre of the cloud gets more and more compressed and, in turn, gets hotter. This dense, hot core is the beginning of a new star.

We all have heard about the discovery of a new plant but no one really pays attention to the type of strategies and methods astronomers use to identify a new planet. Astronomers study the astronomical sense of space, what truly lies away from our peaceful planet earth. One famous Theoretical Physicist known as Stephen Hawking’s is our modern day Einstein. Hawking’s has been in involvement of the discovery of many planets and far away galaxies. There are many different types of methods, and tools are used to discover, and identify new planets and galaxies. Radial Velocity method, the astrometry method, Gravitational Microlensing method are used along with many other methods to discover Exoplanets in particular. (Cane 2013). Exoplanets are planets

Next what did Edwin Hubble find. He found a place where Andromeda Nebula that is far outside of our star system at a distance of 450,000 parsecs. And he made a settlement when he identified extragalactic the Cepheid variable

For thousands of years astronomers have been observing the skies in awe, discovering the complex facts of our Universe. From the uncovering of a Sun centered Solar System, to the theory of the constant expansion of the Universe, this quick astronomical research advancement has made it possible to dig even deeper into the complex state of our Universe. With this constant discovery of facts, there is one question that boggles many people’s minds: could there be life elsewhere in the Universe? In the following pages, I will expand on the subject of exoplanets, which are planets that orbit a star outside of our Solar System . For the purpose of this research paper, I will only concentrate the findings in our Galaxy, the Milky Way. I will expand on what exactly makes a planet habitable, on exoplanets, on goldilocks planets and on the research involved in finding planets with life.

This is done when such a body passes in front of its parent star, from our prospective. Light from the star interacts with different molecules in a planets or moons atmosphere. From this type of researches we can narrow down where to look for life.

First, however, scientists must observe the exoplanets and photograph them. Researchers utilize space-based telescopes to survey regions of deep space and capture photographs of those regions. Once a space-based photometer has multiple photographs of an exoplanet, scientists use the spectroscopy data to determine the mass, size, orbital period and eccentricity of the orbit, radius, and density of the exoplanet. Next, scientists use this data to better comprehend the process of planetary evolution. In addition, these statistics allow scientists to discover Earth-sized exoplanets and detect biosignatures that indicate the presence of life. Matt Mountain from the Space Telescope Science Institute in Baltimore says, “Just imagine the moment, when we find potential signatures of life. Imagine the moment when the world wakes up and the human race realizes that its long loneliness in time and space may be over -- the possibility we're no longer alone in the universe.” (“Finding Life Beyond Earth is Within Reach”). Should we discover life on exoplanets, our views of outer space will change greatly, and we will enter a new era of space study. The discovery of extraterrestrial life will also influence our philosophy about the world. Additionally, it is known that the material around stars combine to form planets. Space-based telescopes study this material in order to give scientists better knowledge of how these materials combine to form planets. Thus, the examination of exoplanets provides data useful for studying planetary system evolution, including how planetary orbits form and whether planets form outside of the solar system and then move inward or form inside the solar system. The study of exoplanets can also help scientists comprehend why rocky planets such as Earth are closer to the
