SOLAR SYSTEM About 5 Billion years ago‚ y There was no Sun‚ no Earth& no Moon y Only cosmic dust and gasses drifted in the darkness of space SOLAR SYSTEM THEORY The solar system was formed by a slowly spinning cloud of gas and cosmic dust‚ gradually the cloud began to spin faster and faster this formed a large spinning whirl at the centre and smaller whirls surrounding it at various distances. SOLAR SYSTEM THEORY The huge and heavy centre became hot enough to start thermo nuclear

Advantages and disadvantages of solar energy: The major benefit of solar is avoiding green house gases that fossil fuels produce. The first and foremost advantage of solar energy is that it does not emit any greenhouse gases. Solar energy is produced by conducting the sun’s radiation – a process void of any smoke‚ gas‚ or other chemical by-product. This is the main driving force behind all green energy technology‚ as nations attempt to meet climate change obligations in curbing emissions. Italy’s

Madison Gaddy Lunar & Solar Eclipse Lunar Eclipse occurs when the earth comes between the sun and the moon in such a way that it blocks the sun’s rays completely from reaching the moon. Solar Eclipse occurs when the moon passes between the earth and the sun in such a way that the sun is totally blocked from view. Lunar Eclipse only occurs on the full moon night which means that the moon is on the other side of the earth from the sun. Solar eclipse always occurs on the new moon which means that

Solar Powered Cars By SolarCars on October 25‚ 2009 Cars that run on fossil fuels are still standard‚ but many would like to replace those diesel or gas engines with alternative fuels. One promising possibility is to develop solar powered cars. Although this is not yet a reality‚ prototypes have been built and proven to be functional and now many researchers are trying to find ways of using solar energy to power cars. Solar powered cars would have many advantages over those that run on fossil

was a part of NASA’s ERAST programme (Environmental Research Aircraft and Sensor Technology). It was developed by NASA and Californian company AeroVironment Inc. ERAST programme develops pilotless solar powered airplane technology. The HELIOS construction is based upon its predecessors like NASA’s solar plane Pathfinder‚ which was successfully tested a few years prior to HELIOS. Due to its speed HELIOS was able to fly over the same spot for days or weeks‚ therefore‚ in the future such aircrafts could

astronauts when an amount of radiation gets through the walls of a space shuttle or station and enters the body. Solar radiation usually affects astronauts walking in space‚ outside of their space shuttles‚ but sometimes it can even affect the people on Earth‚ causing electricity failures. Many people - astronauts mostly- fear the consequences of solar radiation‚ due to the fact that solar radiation can cause dangerous effects to one’s health. Even though sometimes the effects are so minor‚ you can

Stars A star is a massive‚ luminous sphere of plasma held together by gravity. The nearest star to Earth is the Sun‚ which is the source of most of the energy on the planet. Solar System The Solar System consists of the Sun and its planetary system of eight planets‚ their moons‚ and other non-stellar objects. It formed 4.6 billion years ago from the gravitational collapse of a giant molecular cloud. The vast majority of the system’s mass is in the Sun‚ with most of the remaining mass contained

Solar Power In India India’s power sector has a total installed capacity of approximately 1‚46‚753 Megawatt (MW) of which 54% is coal-based‚ 25% hydro‚ 8% is renewables and the balance is the gas and nuclear-based. Power shortages are estimated at about 11% of total energy and 15% of peak capacity requirements and are likely to increase in the coming years. In the next 10 years‚ another 10‚000 MW of capacity and investment of about Rs. 24 lakh crore are required. Fortunately‚ India lies in sunny
