The oldest rocks in the crust by radioactive decay of age were identified as slightly less than 40 billion years old. Using the same method the age of the moon rock samples from roughly 4.1 billion years old the oldest dated rock samples up to 45 billion years old. Some meteorite samples has more than 40 billion years old. For all the evidence obtained about the solar system 4.6 billion years old. As the Milky Way has about 15 billion years old, so the sun and the plas and the Milky Way is only one-third of the age. Although there is no direct way to measure the age of the sun, but as the HR diagram main sequence stars on an orange star general appearance, but with the sun just is a quality, aged about 46 billion years old, spent half of it main sequence stars in the career should be expected

There are different definitions of Astronomy. Some define it as a branch of science dedicated to the study of the motions and natures of celestial bodies, like plas, stars, and galaxies. Others say it is the study of objects and matter outside the earth's atmosphere and of their physical and chemical properties. Still others would say it is the study of everything, because it's a study of the universe and everything is part of the universe. All three definitions are accurate, but however you define it, there are many fields within Astronomy. Co *** ologists study the Universe as a whole, including its beginnings. Astrometrists measure great distances. Plaologists study plas within our own Solar System as well as those orbiting distant stars. Radio Astronomers use radio-telescopes to study the Universe. There are also Mathematical Astronomers who use numbers, calculations and statistics to explain the universe. Astronomy is not a "stand-alone" science. It bines areas from a number of other fields, including mathematics, chemistry, geology, biology and physics. In fact, physics is such an integral part of the field that many astronomers are also known as Astrophysicists. The ancient Greeks were the first to start developing astronomy theories about the design of the Universe. There have been many astronomers throughout history who have played important roles in the science. Many have later been proved wrong as our knowledge and technology improved, but if not for the earlier work, later scientists would have had nothing on which to base their research Astronomy is the study of the universe beyond the Earth's atmosphere. The science does not claim to predict your future or lend credence to the practises of Astrology. Rather through the use of Physics principles, Astronomy explains the evolution of the universe and through sound mathematical simulations forecasts its development. Although Astronomy has been around for thousands of years and is perhaps the oldest science, it is only in the last century and particularly the last few decades that we have developed the technology to study the universe in greater detail. Every day we are gathering new data on everything from galaxy formation to black holes to the big bang itself using a staggering array of multi-wavelength telescopes on the ground and in space. We continue to answer one of humankind's most burning questions: "What is out there?" but perhaps more impressive is the great progress that has been made in answering the question "How does it all work?"銆
