From Wiktionary under the GNU Free Documentation License. Astronomy (from the Greek words astron (ἄστρον), "star", and nomos (νόμος), "law") is the scientific study of celestial objects (such as stars, planets, comets, and galaxies) and phenomena that originate outside the Earth's atmosphere (such as the cosmic background radiation). It is concerned with the evolution, physics, chemistry, meteorology, and motion of celestial objects, as well as the formation and development of the universe. Astronomy is one of the oldest sciences. Astronomers of early civilizations performed methodical observations of the night sky, and astronomical artifacts have been found from much earlier periods. However, the invention of the telescope was required before astronomy was able to develop into a modern science. Historically, astronomy has included disciplines as diverse as astrometry, celestial navigation, observational astronomy, the making of calendars, and even astrology, but professional astronomy is nowadays often considered to be synonymous with astrophysics. Since the 20th century, the field of professional astronomy split into observational and theoretical branches. Observational astronomy is focused on acquiring and analyzing data, mainly using basic principles of physics. Theoretical astronomy is oriented towards 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. Amateur astronomers have contributed to many important astronomical discoveries, and astronomy is one of the few sciences where amateurs can still play an active role, especially in the discovery and observation of transient phenomena. Old or even ancient astronomy is not to be confused with astrology, the belief system which claims that human affairs are correlated with the positions of celestial objects. Although the two fields share a common origin and a part of their methods (namely, the use of ephemerides), they are distinct. 2009 has been declared by the UN to be the International Year of Astronomy 2009 (IYA2009). The focus is on enhancing the public’s understanding and engagement with astronomy. From Wikipedia under the
GNU Free Documentation License What kind of place is usually the best place for astronomy? Q. So i bought a decent binocular and want to start astronomy, but whereever i go there is some sort of a light source like a lamppost. What place is usually the darkest? Asked by Young P - Thu Feb 26 22:12:44 2009 - - 4 Answers - 0 Comments A. as far away from the lights as you can get. If you have a school nearby you can go out into the middle of the athletic field and that will help (provided the lights aren't on). The top of a building gets you above a lot of the street-level glow. By the way, which kind of binocs did you wind up getting? Visit my 'resources' page below for some links to free downloadable star atlases and planispheres. I've also got a list of binocular objects and the Astronomy League's page for the binocular Messier challenge.

I know he explained gravity but I don't understand how Newton s work linked physics and astronomy? Thanks in advance Asked by thuyaamz - Sun May 10 19:02:12 2009 - - 1 Answers - 0 Comments A. Here's the answer in Newton's own words (from the introduction of Book 3 of his "Principia"). Slightly re-written from a published translation of Newton's original Latin: Rules of Reasoning in Science: Rule 1: We are to admit no more causes of natural things, than those that are both relevant and sufficient to explain them. Rule 2: Therefore, to the same natural effects, we must so far as possible assign the same causes. Rule 3: The properties of objects which are found to belong to all the objects within the reach of our experiments, are to be assumed to be universal properties of all objects in the universe. Those ideas may seem "obvious" today, but they were completely different from ancient Greek and medieval science, which for… [cont.] Answered by Rob T - Sun May 10 19:35:38 2009 What are some good ideas for a research paper on astronomy?
Q. I need to write a 3-4 page research paper on astronomy (double spaced) what are some good and unique ideas? Asked by djsqueakz - Mon Feb 9 17:38:30 2009 - - 5 Answers - 0 Comments A. There are many things that you could write about. You can write about the big bang theory, a star's life cycle, light years, all the exoplanets that NASA has discovered, reasons why Pluto ain't a planet anymore or the different types of galaxies. Exoplanets Big Bang Theory Stars Dwarf Planets Oh and you can write a research paper about Titan. Titan is an interesting moon and theres much to learn about it.
