A Brave New World : Scientists Hope To Have Discovered The Next Earth

According to the International Astronomical Union (IAU) to classify an object as a planet it must have three qualities. One it must orbit a Sun or Star of some kind. Second it must big enough for gravity to compress it into a big round ball. And lastly it must be big enough to pull neighboring objects into the planet itself or sling-shot them around the planet and shoot them off into outer space. The place for my planet is in the Triangulum Galaxy. The Triangulum Galaxy is a spiral galaxy about 2.7 million light years (25761569076837520000km)away from Earth. The solar mass of the Triangulum Galaxy is 50 billion Mʘ (standard unit of mass in Astronomy). This galaxy has about 40 billion stars which is 1/5th of how many there are in the Milky Way Galaxy. And 1/25th 's of the Andromeda Galaxy. The name of my planet is Frigusodayin (Cold Air)(Latin, Armenian). The first rule of classifying a planet states that it must orbit a Sun or Star. The Sun my planet will orbit is called WASP-56. Some properties of WASP-56 are that this star has an apparent magnitude of 11.48. Apparent magnitude is the brightness of an object as seen from Earth. The higher the apparent magnitude the brighter it is (Our Sun 's is 26.7). This star is a G6 star which is part of the G-Type main-sequence star group. The G-Type main-sequence star is a main sequence star of spectral type G and luminosity level V. These types of stars have about 0.8 to 1.2 solar masses. Solar masses being the mass of a sun or star

A red dwarf star’s HZ, for example, would be much closer to the star itself compared with that of our sun. It is also important to determine the planet’s size and mass, which is imperative in deciding whether it can sustain an atmosphere. Maintaining an atmosphere is essential for life to exist and small a planet with a small gravitational force at its surface may not be capable of retaining one. The Kepler transit data can only measure planet masses, diameters, orbital periods, and parent star types and although this information is useful for determining habitable zones, further data is required to determine true habitability. The latter can be done by studying the composition of the exoplanet’s atmosphere.

The exoplanet known as Kepler-453b is what is known as a circumbinary planet. A circumbinary planet is a planet that orbits two stars, and Kepler-453b is the tenth such planet discovered so far. It is a timely discovery not only because it was discovered at around the same time that news broke out of the world’s superpowers looking to make Star Wars a reality by waging war in space, but also because the real-life Tatooine was discovered by chance in a classic case of being in the right place at the right time.

on measurements of the planet's brightness. Like all planets, this new one presumably shines by

Outer space is a realm of new discoveries and possibilities. There is one particular planet in our solar system that is brimming with these possibilities. However, for nine years it has not actually been considered a planet. The “dwarf planet”, Pluto, has been overlooked and misrepresented in astronomy and planetary science. Since being demoted from planet status to dwarf planet status, little Pluto has raised some big questions about what defines a planet and what does not. In this paper, I will attempt to persuade you that Pluto should be promoted back to its original planet status. First, I will give you a brief history of Pluto, from its discovery to what prompted its reclassification. Next, I will explain the definition of a planet as given by the International Astronomical Union (IAU) and the definition’s flaws. Finally, I will discuss the recent discoveries of the New Horizons mission and how these new discoveries should lead to the reclassification of Pluto to its original planet status.

much a star wobbles or goes around the centre of gravity of the exoplanet and star, the violent wobbles must conclude that 51 Pegasi b is a Jupiter sized exoplanet. Hd209458 b is also a Jupiter sized exoplanet, which may have been determined using the calculation or the wobble method, having similar affects to its host stars light spectrum as 51 Pegasi b has on its host star. Astronomers are unsure whether the exoplanet named Kepler 22b is a larger Earth or more of a mini Neptune, as it is boarder line between a rocky planet and a gas dwarf.

A red dwarf star is considered to be a great spot for life because of its potential for long term habitability. For earth, the habitable zone it resides in lasts only about 7 to 10 billion years. Compare that to a red dwarf, where a habitable zone can last for for a span almost five times greater than that for earth. Thus making a red dwarf a good candidate for life to grow, develop and become advanced. Another point to consider is that many planets orbiting M dwarf, red dwarf stars are highly likely to have large amounts of water which suggests the idea that there could be many habitable planets surrounding a red dwarf star. However, red dwarf stars have a few big problems. Due to the low luminosity of a red dwarf, planets have to be relatively close for it to be in the known habitable zone. And by being so close, planets face hostile conditions. One condition is the barrage of stellar wind, which could strip a planets atmosphere. Another is that the planet could be tidally locked, so only one side would face the star. Lastly, is that red dwarf stars are emit extreme EUV and X ray

Findings revealed that the system is located 39 light years from the solar system and is in the constellation of Aquarius. The system is formed of at least seven planets that orbit around a star that according to trappist.one is 12 times less massive than the Sun (“About Trappist-1 p.1”). Following findings made by the TRAPPIST, Spitzer space telescope, the Very Large Telescope, UKIRT, the Liverpool Telescope, and the William Herschel Telescope revealed new planets in the system and more facts about the composition of the planets. The discoveries made about the planets in the Trappist-1 system show surprising and promising aspects that might be promising evidence for a habitable

We are often presented with useful information in the search for new information, and here it comes in the form of two research papers. They are: ‘HD 219134b: A transiting rocky planet in a multi-planet system at 6.5 pc from the Sun’ by F. Motalebi et al. and ‘An Earth-size planet with an Earth-like density’ by F. Pepe et al. Both papers provide research findings on two close-proximity exoplanets around their respective host stars, with the main focus of

The new planet is known as HD 219134b and it followed NASA's discovery of the planet Kepler-452b, discovered by the Kepler telescope. The Kepler-452b apparently resembles Earth much more than the HD 219134b exoplanet. It maintains a 385 orbit and its host star is only 20 percent brighter than the Earth's sun. However, HD 219134b is much closer to Earth than the Kepler-452b, and for that reason, scientists have high expectations from it.

Within the article Will We Ever Discover a Twin Earth? 20 Big Questions About the Future of Humanity, I found many of answers to the questions asked very interesting and thought provoking. With my unscientific opinion about there being other life forms in space already formed, I was glad to read Aki Roberge state that she believes that we will discover a twin Earth and that scientists have “found that planets around other stars are far more abundant and diverse than scientists imagined just a couple of decades ago.” The universe being as big as it is, I wouldn’t be able to believe that we are the only form of intelligent life.

This telescope has found over 960 planets already and is still finding more. The telescope has already found six rocky planets, one of which is Kepler-186f.

Astronomers aboard NASA's planet-hunting spacecraft Kepler just discovered Earth 2.0 aka Kepler 452b. The planet is located 1,400 light-years away in the constellation Cygnus. The discovery of Kepler 452b brings the total number of confirmed planets by the Kepler project to 1030.

The Kepler mission is searching for planets that are enough like Earth to be considered habitable. Discovered in January 2015, Kepler-438b looked like an excellent candidate. The planet fit the two key characteristics for a Kepler candidate to a T. The first of these is that the planet has to be rocky, like Earth or Mars, rather than gaseous, like Jupiter or Saturn. The second is that it has to orbit its star in the habitable zone, where temperatures are neither too hot nor too cold to support life.

Let’s take a look at one of the first successful ways to find exoplanets, radial velocity, or watching for wobble, which is the gravitational interaction between a star and a planet. Radial velocity is one of the first successful way a star with a gravitational field that is much more powerful than a planet with less gravity than the star and its effects makes the star wobble and the size of the wobble can tell us how big or small the planet is. Another way of locating a planet is to find it during it transition, that is when it is in the directly between it host star and where it is being observed. The observer will notice a change in the light because of the planet blocking out the light from the host star. The best example of a planet being in transit is thinking of an eclipse, when our Sun is being blocked out we lose light for some time. When a planet is in this phase we are searching for shadows of other planets it is one of the best clues because the light curve indicates a lost in brightness. The light curve can give us a great deal of information about what size of the planet is or if there are more than one planet circling that star. The more light that is block will create a deeper light curve and that tell us that the planet is big. The longer the light is blocked out from the star also can tell us how far away from the host
