here comes the sun history

Energy for life processes basically comes from the sun. During photosynthesis, green plants absorb energy from the sun to make glucose and oxygen from carbon dioxide and wate..

The sun is the most enormous and direct, source of energy. Where does this enormous energy that the sun radiates come from? The source of this energy was not known to mankind until the year 1939. It was a German physicist, Hans Bethe, who proposed that the s..

Sunlight falling on the earth's surface equals 50,000 times the energy used each year by man. Almost all our energy comes from sun. The sun's nuclear energy is responsible for the tidal energy, heat energy stored in water, the chemical energy stored in plants, and the ..

Atmospheric Refraction - Atmospheric refraction is the shift in apparent direction of a celestial object caused by the refraction of light rays as they pass through Earths atmosphere. The twinkling of stars and variation in size of the Sun are due to atmospheric refraction of starlight. T..

The Solar Energy - Sunlight falling on the earth's surface equals 50,000 times the energy used each year by man. Almost all our energy comes from sun. The sun's nuclear energy is responsible for the tidal energy, heat energy stored in water, the chemical energy stored ..

Nuclear Fusion - The sun is the most enormous and direct, source of energy. Where does this enormous energy that the sun radiates come from? The source of this energy was not known to mankind until the year 1939. It was a German physicist, Hans Bethe, who proposed that..

Asteroids - Asteroids are very small planets of rock and metal, which revolve round the sun mainly between the orbits of Mars and Jupiter. This area is known as the asteroid belt. Most of the asteroids have a diameter of only 1 kilometer. But some of them have diameters of more than 100 k..

Comets are like dirty snowballs from space. They are made up of rocks, ice and dust. They are basically aggregates of dust and frozen gases. The head of a comet is only a few kilometers wide, but its tail can be millions of kilometers long. Comet Comets orbit the sun in long, looping orbi..

"Remote Sensing" - can be defined as obtaining information about an object by observing it from a distance and without coming to actual contact with it. Infact when we see an object and understand what it is, our eye is sensing that object remotely. This is a broad definition. But we gene..

When a powerful beam of light is passed through a colloidal solution placed in a dark room, the path of the beam gets illuminated and appears as a glow in the colloidal solution. This is because of scattering of light by the colloidal particles...
