Most scientists think that our solar system was made from a nearby star‚ called the supernova. These scientists believe that the explosion of the supernova squeezed a nearby cloud of dust‚ causing it to collapse. When the gravity gathered the dust together‚ it formed something called a solar nebula. Soon‚ the cloud became hotter‚ a disk of gas surrounding it. Molecules gathered in a clump as the disk got smaller. Scientists believe in this theory using technology. They used this technology to observe

The earth receives extremely large amounts of energy coming from the sun. Solar energy has become a number one option for a future reliable‚ greener energy source. An article by the National Academy of Engineering‚ Make Solar Energy Economical‚ has proposed this issue as one of the many challenges engineers face this 21st century. The academy emphasizes‚ the sun’s “availability far exceeds any conceivable future energy demands. It is environmentally clean‚ and its energy is transmitted from the sun

Why Do We Need Solar Energy? With the world’s natural resources depleting rapidly‚ humans must find a way to compensate. This society has milked oil‚ coal‚ gasoline‚ lead‚ uranium‚ and many other of these reservoirs in our Earth for hundreds of years and much has been done. Asphalt was used for our roads and highways‚ coal was originally used for heat before there was oil‚ and even water was used as a form of electricity on many rural farms. Luckily‚ more companies around the world are waking

"Environmentalists Against Solar Power" Summary Peter Maloney writes in his article‚ " Environmentalists Against Solar Power" that solar power projects are facing major scrutiny‚ not from the coal or oil industry‚ but from environmentalists. Maloney says that Southern California is pushing for solar power in the desert cause the amount of sunlight with virtually no clouds‚ "but its also the home to the Mojave ground squirrel‚ the desert tortoise and the burrowing owl‚ and to human residents"

a) Photovoltaic solar power systems are environmentally beneficial because they release no harmful pollutants or emissions such as CO2. These systems operate throughout the day‚ implying it is sunny‚ and do not rely greatly on other power sources to operate‚ thus there is less of a toll on the environment in terms of external resource usage. An environmental cost of photovoltaic systems is the manufacturing of these systems that uses energy and could possibly contribute to more atmospheric pollution

The Size of the Solar System Overview • Become familiar with the scale of the planets vs. their distances. • Get an overview of the solar system. Introduction It is easy to flip to the index of an astronomy textbook to discover that‚ say‚ the Sun lies 150 million kilometers away from Earth. It is far more difficult (if not impossible)‚ however‚ to picture this distance in the human mind. In this exercise‚ we will learn to access the often unpalatable distances encountered in astronomy
