Beginning with a hundred(100), a thousand (1000), a million(1,000,000), a billion (1,000,000,000) even a trillion (1,000,000,000,000). These are words that occur in most of our everyday speech; as quantifiable proper nouns or financial sums. First let's take a moment to understand the magnitude of these numbers and to appreciate the differences among them.
One thousand is easy enough to understand, otherwise called millennium for years; at the rate of one number per second, you could count to a thousand in about 16 minutes. However, if you wanted to count a million, you would need more than two weeks of counting at the rate of one number per second, a minimum of 16 hours per day (allowing 8 hours per day for sleep). Facts are that a young boy beginning a count to a trillion at ten would be closing off on numbering proximately at 61- the better part of an entire human lifetime.
The earth is estimated by NASA to be 4.543 billion years, hence my beginning expository on number variableness. So much study and research has been invoked as regards the universe's existence exceeding hundreds, thousands, even millions of years. Simply put, the universe is the totality of all space, time, matter and energy.
Over the last 60 years, NASA has launched a variety of spacecraft to explore our solar system. The Moon, which is the closest celestial body to Earth, was the logical first target. Subsequent fleets of space probes started exploring other planets such as those relatively close and those in the more distant reaches of our solar system as well as comets, asteroids, and other small bodies. Satellite communication stations on Earth make these flights into deep space possible.
The missions are providing insights into the physical nature, chemistry, and biology of worlds outside of ours. They will help inform future searches for life beyond Earth and opportunities for human exploration and habitation. Understanding the planets and small bodies of our solar system helps answer questions about its formation, how it reached its current diverse state, how life evolved on Earth and possibly elsewhere, and what characteristics of the solar system lead to the origins of life. A proper study of the earth would entail the concept of astronomy.
Nature itself offers no greater splendor than the starry sky on a clear, dark night. Silent and jeweled with the constellations of ancient myth and legend, the night sky which has inspired wonder throughout the ages. A wonder that leads our imaginations far from the confines of mother earth and the pace of the present day and lures out into the distant reaches of space and cosmic time itself.
Astronomy, born in response to the wonder called earth, is built on two of the most basic traits of human nature: the need to explore and the need to understand. Through the interplay of our curiosity , discovery, and analysis which is the key to exploration and understanding.
Our place in space of all the scientific insights attained till date, one stands out boldly: Earth is neither central nor special though we inhabit unique places in the universe. Astronomical researchs, especially within the past few decades, strongly suggests that we live on what seems to be an ordinary rocky planet called Earth, which is one of nine known planets orbiting a giant star called the Sun, which is one star near the edge of a huge collection of stars called the Milky Way Galaxy. One of such galaxies among countless billions of others spread throughout the observable universe.
