Extrasolar planet

Imagine that out of the infinite stars and planets in the vast universe, only one solitary planet can sustain life. Heavily disputed arguments have arisen about whether humans are the sole intelligent beings in the universe. Scientists continuously search for the answer, but the search has not as yet yielded positive results. Billions of dollars have been spent in research, causing controversy about whether scientists should invest in the hunt for extraterrestrial beings. Due to inadequate technology

ESS AS 3.6: The features of distant planets – how do we know? 1 INTRODUCTION Exoplanets, also referred to as extra solar planets, are planets which orbit around stars in planetary systems other than our own Solar System. The first exoplanet that was ever discovered was of PSR B1257+12 A in 1992, since then we have discovered approximately 1932 extra solar planets, 1222 planetary systems and 484 multiple planet systems. A wide range of techniques are used by astronomers to find exoplanets, most of

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

Tate M. Stagpoole Introduction Extra-terrestrial planets (Exoplanets) have captivated humans for hundreds of years, the idea that there are planets exist outside of our solar system. There are two types of planets: terrestrial planets, or rocky planets and gas giants. With the development of high zoom telescopes and arrays, we as a race, now have the technology to observe and recognise planets outside our solar system. NASA missions such as Hubble and Kepler have yielded

In the recent scenario, it seems like the earth is very small as we got connected to every part of the world. Mars and the moon have become our regular visits and it seems that mankind may step on Mars in this century. In the age, if advanced technology, Humans have covered trillions of miles in the universe through high-tech telescopes, so it is more likely that humans may find extraterrestrial life before they come finding humans. Astrophysicists and alien astronomers have been

According to the article, “What Do You Know about Area 51?”, several people argued that they witness some paranormal activities in Area 51. Area 51 is a facility located in Nevada for developing aviation technology. There is no proof explaining why the paranormal happenings are coming from there. Nevertheless, the witnesses claim that these happenings are all related to the aliens. Additionally, they assume the high government officials would have communicated with the aliens in Area 51. The evidences

to be considered if a place is habitable are: presence of organic materials, water and energy sources. Habitability of the planet also takes into consideration, nearness of the planet to the sun, the

galactic home. Unlike a regular spiral, the Milky Way galaxy is a barred spiral that was comprised with two minor arms and spurs. One of the spurs, Onion Arm, contains the sun and the solar system. There are eight planets in our solar system and they are all unique. Yet, out of all the planets, Saturn, perplexed many astronomers with its discoveries. First and Foremost, the “chemical compounds in its upper atmosphere color, its cloud bands in subtle shades of ivory and broad, lacy rings that encircle

These techniques that the astronomers used in detecting the properties of the planets is more likely in detecting the properties of the exoplanet and other far object in the solar system like the Pluto. Even if it is so far away, Astronomers were able to see exoplanet by observing the host star with various method they used like transit method, the one method they used to find the trappist-1. Observing distant star requires the use of the space telescope like the Kepler telescope and spitzer telescope

Someday we might be able to identify a planet and say that it is just like Earth. Finding life outside of Earth is within reach. Extraterrestrial life is not a myth and there are many reasons why such as evidence from National Aeronautics and Space Administration (NASA), discovery of Earth-like planets that orbit a sunlike star, and discoveries on planets closer to Earth. Many scientists believe that we are one of many species in the universe that exist on more planets than just Earth. It would be silly
