transport and communication have made the word shrink in size. Men and things and news and views can go around the globe today with lightning speed. Man has already landed on the moon and a man-made satellite has just completed it’s voyage through the solar system. Our life has become healthier and longer. Modern hygiene‚ sanitation‚ medicine and surgery are conquering more and more physical and mental ills day by day. We now know and experience the joys of good health and longevity. Through the cinema

lasted from Earth’s inception to about 4 billion years ago. Initially‚ there was nothing but an enormous cloud of gas and dust. Progressively‚ the cloud began to rotate and contract and about 10 million years later the major planets that make up our Solar System - including the Earth - formed. During the Haden period our planet had an atmosphere deficient in oxygen‚ there was no life on it‚ its surface was mainly molted lava and the planet was constantly bombarded by meteorites.

Cosmologists don’t restrict themselves to our Solar System either‚ recommending that we ought to take a gander at diverse universes. Researchers want to utilize interferometry–an investigative method that executes lasers‚ which is utilized as a part of space science and also other fields– to discover planets

2010 Why Should We Explore Jupiter’s Moon Europa? The planet Jupiter‚ some 500 million miles from Earth is a very unique planet. Besides being 1200-1500 (estimates vary) times larger than the Earth‚ The planet Jupiter is surrounded by a small solar system by itself. The planet Jupiter has some 72 moons orbiting it at present count‚ and these moons come in all shapes‚ sizes‚ and physical variations. Many of these moons have quite interesting characteristics‚ such as the moon Io‚ which has volcanic

While when a average star becomes unstable they shed their outer layers and create a planetary nebula. Which has the potential to create whole solar systems. After the star sheds‚ it leaves it core exposed‚ and these core become white dwarfs that use stored thermal energy from its fusion days to stay luminicient. But eventually the core begins to cool‚ and after aa lot of time become black dwarfs (Cooled

An asteroid is a minor planet in the inner solar system‚ the term minor planet has historically been applies to any astronomical object orbiting the sun that did not show the disk of a planet. Asteroids supposedly don’t have the characteristics of an active comet but their volatile based surfaces resemble comets more closely than originally thought.(1) Whereas a meteorite is a small rocky or metallic body that travels through space‚ they are significantly smaller than asteroids and range in size

After Apollo 11 succeeded in the first manned mission to land on the Moon in 1969‚ people’s interests were gradually leaving the Moon and went on to Mars‚ which is the most similar planet to Earth in the solar system. In such a current of public opinion‚ the U.S. and other countries have been trying to send human beings to Mars. However‚ today‚ there is a debate as to whether we should continue making efforts to send mankind to Mars‚ or not. Some people say that it is not worth the expense and
