Detecting extra solar planet from the earth is difficult. Unlike other stars, which are fuelled by nuclear reactions, extra solar planets faintly emit thermal infrared radiation. Recently, eight new extra solar planets have been discovered and it has been observed that their orbital period is longer than duration of three years (Lissauer et al 1).
These planets were “identified through observation of periodic variations of the Doppler shift of light emitted by the stars in which they are connected” (Lissauer et al 1). Some are larger than Saturn is while other even larger than Jupiter. They go round their stars closer than the other planet that goes round the solar system. Those that defy this rule travel on a high elliptical path (Scharf, 143-9). Scientific advancement will continue in the Astronomic world. This will happen as man try to improve life by discovering other habitable

In the past few years, scientists have been indulged in such kind of imaginations which are a sight of both excitement and fear. This mind is exploring the possibility of extra-terrestrial life on earth or in the universe. Recent studies have convinced them, at least, that even bacteria are classified under this kind of life.
Venus is the second planet from the sun in our solar system and was named after the Greek goddess of beauty; it has a year with the equivalent of 224.7 days on earth and has been studied by many probes being sent to the planet mainly by Russia but as well as USA and the European space association.
and moons were flying around and some were captured by our sun and began circling around it; 4) the accretion theory, which states that a pile of space dust and rock chunks pushed together into our planet, and another pile pushed itself into our moon. Then the moon got close enough and began encircling the earth; 6) the gas cloud theory, which presupposes that gas clouds were captured by our sun but instead of being drawn into it, they began whirling and pushing themselves into planets and moons; and the 8) the expanding universe or the big-bang theory, which depends on two major assumptions, namely: the universality of physical laws, and the cosmological principles.
The author states that one of the ways to make use of solar energy is to use photovoltaic cells. The PV modules using arrays of PV cells are used to power a house. The PV modules should point towards the south in the northern hemisphere. They should be inclined at an angle equal to the latitude of the place, so that they absorb the maximum energy.
To this system of nomenclature, greater refinement was added by introducing the term Dwarf Planet. Three conditions must be satisfied in order for a planet to be classified as a dwarf planet. Firstly, they must be large enough to
se rocky core surrounded by a thick liquid hydrogen layer that is covered by another liquid layer of mixed hydrogen and helium that dissipates to the gaseous outer layer (Saumon, Hubbard, and Lunine, 1992). In order to support life, Saturn would have to be stripped of its
Gemini South telescope is located at Chilean Andes, while Gemini North is located at Mauna Kea in Hawaii. In 2000, scientific operations begun on Gemini in the North while those in the Gemini South begun the following year. The construction and maintenance
This research has been conducted with the aim of unmasking the potential that the solar energy possess if it was fully exploited. In this case, various aspects relating to solar energy harnessing have been highlighted to enlighten readers on how to install their own solar panels to tap this environmental friendly energy source.
The author states that solar energy has many advantages in Hong Kong since there is abundant sunlight. High-rise and high-density urban environment often create difficulties for energy applications. There have been interesting results derived from using solar systems. Wind and solar energy have been proposed to be used in the "Hong Kong Disneyland”.
