terrestrial and jovian planets. They are different in their position, composition and other features. First of all, let us see what are the jovian and the terrestrial planets. Jupiter, Saturn, Uranus and Neptune are the jovian planets. Mercury, Venus and Earth are the terrestrial planets. One of the main differences that can be seen between terrestrial and jovian planets, is their surfaces. While the terrestrial planets are made of solid surfaces, the jovian planets are made of gaseous surfaces.…

The sun energy reaches earth as UV visible and Infra-red radiation. UV radiation is an invisible part of electromagnetic spectrum. Only 5 % UV from sun reached the surface is play the major role to the degradation of coating .Visible light wave (295-400 nm) seen by human eyes. Around 50% of the suns energy occurs in this region which gives the perception of colour.45 % of total solar energy is in IR region (700-2500 nm) .The purpose of IR reflecting pigment is to keep the object cooler than…

Characteristics of Sun As matter of fact, our solar system is composed of the Sun and all things which orbit around it in the nature of the Earth, the other eight planets, asteroids, and also comets. Even though the sun is a normal star but it is much closer to us compared to any other star. By studying the sun, we do notonly acquire about stars and galaxies but in the end, we can also learn more about the universe. Another significance of learning more about the sun is we will apprehend more…

has inspired many with its numerous potential applications, it has also terrified a lot of pessimists. Teleportation is a technology that promises to provide instantaneous travel from one location, for instance, Bangkok to another site far from the earth like the Alpha Centauri star system. Such power is one that is worth grasping after. Some have gone ahead to suggest that such power can be humankind’s saviour and additionally any incidental technology from it could eventually alter what it…

discovery of Eris in 2005 that astronomers began to question what defines a planet. After the discovery of Eris and other celestial objects such as MakeMake, Pluto along these new discoveries have been defined as dwarf planets. They are categorized as dwarf planets because they are smaller compared to the other planets and with their size, are not able to clear other objects out of its path. Since the discovery of Eris, the largest known dwarf planet, the number of planets in our solar system…

before the era of the Jetsons, and technology is finally catching up. The concept of a space elevator is fairly simple a ribbon or tether made of carbon nanotubes is suspended from a satellite that orbits with the Earth in geosynchronous orbit, then robots powered by energy beamed from earth climb into space and then slingshot off the tether out to the rest of the universe riding the gravitational pull of planets. According to Dr. Bryant it costs roughly $23,000 per kilo of cargo to get into…

The four planets that make up the terrestrial planets are commonly known to us as Mercury, Venus, Earth, and Mars (Kay, 2013, p. 216). The reason that terrestrial planets are grouped separately from the rest of the solar system is because they are all structured very similarly and all have surfaces most like that of the planet Earth. Another aspect that separates these four planets from all others is the fact that they are all located the closest to the Sun. Terrestrial planets can be easily…

the honey, as it has been blessed into creation by the flowers which bloom on this earth. These flowers blossom and grow tall as they provide nectar for bees, creating the sweet deliciousness honey is today. This concept is very much similar to the day a man – no, a Saint – came to this world, showing humans what emotion, what power lies deep within us: love. Years and years ago, when men and women stood on this earth unknowing of all of the wonders that lay behind their crystal blue sky, a…

65,000,000 years ago, an entire species was killed off. There are so many different theories of how the dinosaurs dissapeared. There are many different ways to explain the extinction which took place 65 million years ago. One of the main reasons was the possibility of a sudden change in the climate or atmosphere. For instance, a nearby supernova explosion could heat up the upper atmosphere, disturbing the ozone layer. Disturbing the ozone layer could produce large ice clouds which would cool…

PREHISTORIC TO MIDDLE AGE ASTRONOMY Over the course of countless millennia, astronomy has served as a widespread source of curiosity amongst mankind. The stars, planets and various other objects that engulf our skies have captured the interests of this world’s inhabitants, from the simplest of tribesmen to city dwelling scholars and philosophers alike. As early as 32,000 years ago, humans are believed to have been tracking cosmic cycles like our Moon’s phases (Burnham, Dyer & Kanpipe 22).…
