Astronomy (from Greek: αστρονομία) is a natural science that studies celestial objects and phenomena. It applies mathematics, physics, and chemistry, in an effort to explain the origin of those objects and phenomena and their evolution. Objects of interest include planets, moons, stars, galaxies, and comets; while the phenomena include supernova explosions, gamma ray bursts, and cosmic microwave background radiation. More generally, all astronomical phenomena that originate outside Earth’s atmosphere are within the purview of astronomy. A related but distinct subject, physical cosmology, is concerned with the study of the Universe as a whole.
Astronomy is the oldest of the natural sciences. The early civilizations in recorded history, such as the Babylonians, Greeks, Indians, Egyptians, Nubians, Iranians, Chinese, and Maya performed methodical observations of the night sky. Historically, astronomy has included disciplines as diverse as astrometry, celestial navigation, observational astronomy and the making of calendars, but professional astronomy is now often considered to be synonymous with astrophysics.
During the 20th century, the field of professional astronomy split into observational and theoretical branches. Observational astronomy is focused on acquiring data from observations of astronomical objects, which is then analyzed using basic principles of physics. Theoretical astronomy is oriented toward the development of computer or analytical models to describe astronomical objects and phenomena. The two fields complement each other, with theoretical astronomy seeking to explain the observational results and observations being used to confirm theoretical results.
Astronomy is one of the few sciences where amateurs can still play an active role, especially in the discovery and observation of transient phenomena. Amateur astronomers have made and contributed to many important astronomical discoveries, such as finding new comets.

Garden Lighting Made Easy With Solar Power

Garden Lighting Made Easy With Solar Power

Anyone who has ever visited a public garden will know that they are usually illuminated after dark. The garden designer will often use accent lights to highlight specimen trees and shrubs, or to create a certain mood or tone in the garden space. Such a thing can be easily replicated by the home gardener who chooses to use solar lighting fixtures.

It is important to remember, however, that a lighting fixture doesn’t disappear when the sun rises and the loveliest bed of roses can be made ugly by several large and unpleasant spotlights stuck in front of them. This is something to always keep in mind when selecting and placing garden fixtures.

Fortunately, anyone who wants to add decorative garden lighting, but who also wants to retain the charm of their daytime garden can do so with the many stylish and lovely solar powered lights. Because they are designed to be used strictly out of doors, solar fixtures are crafted from the same high-quality materials as traditional, hard wired fixtures. This means that copper, bronze and cast iron appear just as frequently in the solar powered selections as in the others.

Garden lighting can encompass everything from beauty to security and solar lighting fixtures are available for every need. There are sturdy and strong lamp posts, motion detector fixtures and even decorative strings of lights for porches and patios. The important thing for the gardener to do is remember that the lighting should highlight and accent the garden, but not be distracting. A good garden lighting plan takes into consideration the changes that occur throughout the seasons and will really emphasize the well-developed areas of a yard or garden.

The great thing about choosing solar lighting for a garden is that the fixtures can be quickly and easily installed without disrupting the plantings in any way at all. Consider that traditional electrical fixtures would require wiring, which could mean digging trenches to bury the lines, which in turn could mean digging up established beds and destroying roots.

Additionally, the appeal of solar lighting of any kind is that it requires only the initial investment, and then operates entirely for free thereafter. The light bulbs used in solar led lights are very efficient, and they offer an average life span of roughly sixty to one hundred thousand hours. This is compared to the standard fluorescent lifespan of twelve to twenty four thousand hours.

This means that solar garden lighting fixtures are free to operate, require little to no maintenance, install without disturbing the garden and are just as durable, lovely and sturdy as traditional fixtures.

EIB Keen On Financing Solar Farm Project in India

The European Investment Bank has expressed interest in funding solar park projects in India [Images], the Asian Development Bank [Get Quote], senior investment specialist exhaust Don said on Thursday.

“Our discussions with members of the donor’s investment banks and ADB, the Bank has expressed interest in financing the project of the Solar Park in India,” said sideline, and the Clean Energy Expo Asia conference in Singapore.

Financial support is also considered by the U.S. Export-Import Bank and the German KWF, he said, adding that financial support shows growing support for the mission of the National Solar India, which involves the installation of 20,000 MW by 2022.

This would be several billion dollars of investment, on the basis of $ 2,600,000 per MW for large investment projects and $ 3 million investment per MW for the small projects that Purkis said.Noting India has only 14 MW of solar energy in conjunction with the main network, it highlighted two solar park projects in Gujarat and Rajasthan [photos], which reflect the two state governments to support the development of clean energy in the country.

Gujarat has set aside a site of 2,500 acres for the projects of 1000 MW solar power, while Rajasthan has 8,000 hectares to 3,000 MWe-two parks will be part of the second phase of the national mission that requires solar 4000 MW solar installation 2015.The two countries will also be providing infrastructure leveled sites and transmission connectivity options and utilities such as water projects.

Manila-based ADB provides $ 3,000,000 technical assistance projects by organizing and monitoring the funding through its donor members and investment banks, “said Purkis who presented an industry report on” supporting ADB solar energy in India. “Meanwhile, the ADB also support installation missions for Phase I of 350 MW of solar panels, would be 150 MW 5 MW and 200 MW plant will 50 MW per plant.

“We saw a strong expression of the interests of smaller investment 5 MW solar power, about 300 investors, is valid, said the demolition, adding that the Indian government had been expected to make smaller projects first month.ADB also supported this project by providing credit guarantees for lending banks, to convince the 50 percent return on loans for projects of small size are unable to reach a business decision, he said.The banks agreed to support these projects small, where the duration of the loan for 15 years, he added.
