What are the divisions of the History of astronomy?
594615
A traditional division of astronomy is given by the region of the electromagnetic spectrum observed:\n\nOptical astronomy is the part of astronomy that uses optical components (mirrors, lenses, CCD detectors and photographic films) to observe light from near infrared to near ultraviolet wavelengths. Visible light astronomy (using wavelengths that can be detected with the eyes, about 400 - 700 nm) falls in the middle of this range. The most common tool is the telescope, with electronic imagers and spectrographs. \nInfrared astronomy deals with the detection and analysis of infrared radiation (wavelengths longer than red light). The most common tool is the telescope but using a detector which is sensitive to the infrared. Space telescopes are also used to avoid atmospheric thermal emission, atmospheric opacity, and the effects of astronomical seeing at infrared and other wavelengths. \nRadio astronomy detects radiation of millimetre to dekametre wavelength. The radio telescope receivers are similar to those used in radio broadcast transmission but much more sensitive. \nHigh-energy astronomy includes X-ray astronomy, gamma ray astronomy, and extreme UV (ultraviolet) astronomy, as well as studies of neutrinos and cosmic rays.

ASTRONOMY is a map of the sky...\n\nASTROLOGY is using planetary positions to predict the future (which is BS)

Nasa's site definatelly. you can have full studies in Astronomy:) and... I consider the APOD....(Astronomy Picture Of the Day)\nOne picture for everyday since 1995......with full explanation and many links....

I believe this was filed under the wrong category.  This is the astronomy section- not the astrology section.  Astronomy is science.  Astrology is nonsense.

IT STARTED IN THE ORIENT,THE PERSIANS,OBSERVATION IN THE NIGHT SKY,THEY NOTICED THAT EVERY CERTAIN TIME THE POSITION OF THE STARS\nCHANGED IN THEIR POSITIONS IN THE SKY ,THIS IS THE MOST CONDENSED THAT I CAN EXPLAIN

this is not a question about astronomy.\n\nhttp://en.wikipedia.org/wiki/astronomy

This sounds too much like someone's homework!\n\nThe period is far to wide to narrow down any of the categories you want info in.  Perhaps you should actually look it up in some books - you know, actually do some research!

Easy.  Use a newer astronomy text (the newer ones have more pictures than the older ones) or web page and check out the section of seasons.  www.astrnomynotes.com has some good stuff.

Yeah, sure...\n\nStar...moon...universe...\nplanet...comet...\nconstellation...

so much is written coz u asked an explanation\nThe Copernican Model\n(a.k.a Sun Centered)\nAs we discussed in the previous subunit, the Earth-centered model of the universe, refined by Ptolemy, was set firmly in place in the early part of the first millennium. It was not until 1543 that it met serious competition in the Sun-centered model of Nicolas Copernicus.\n\nCopernicus was born in 1473 in Poland and studied, among other subjects, mathematics and astronomy. He is mainly remembered for formally introducing the idea that the Sun is the center of our solar system. This heliocentric concept (sun-centered concept) was a radical idea for his time. Nearly all contemporary astronomers had adopted the Greek Earth-centered model. It was so radical a concept, in fact, that Copernicus waited until the year of his death to publish his famous essay titled, “On the Revolutions of the Heavenly Spheres.” \n\nCopernicus had two main reasons for asserting that the Sun was the center of our solar system.\n\n1. While the Ptolemaic model was very good at predicting the positions of the planets, it wasn't precise, and over the centuries its predictions got worse and worse.\n\n2. Copernicus didn't like the fact that the Ptolemaic model had big epicycles to explain the retrograde motions of the planets. He knew that this could be explained instead by having the Earth also moving around the Sun.\n\nThe true motion of the planets around the Sun is not uniform circular motion, so Copernicus' model still needed to have epicycles. He had 1500 years of post-Ptolemy data to work with, and needed quite a lot of epicycles to make a new set of accurate predictions for the motions of the planets. \n\nThe main simplification of the Copernican model was that the retrograde loops of the planets as seen from the Earth occur naturally as a result of the Earth's motion combined with the motions of the planets.You worked on this problem in the second part of Activity Two. Here are some illustrations to consider.\n\n\n\nThe Ptolemaic Model\nClaudius Ptolemy lived in Rome around 100 AD. His model of the solar system and heavenly sphere was a refinement of previous models developed by Greek astronomers. Ptolemy’s major contribution, however, was that his model could so accurately explain the motions of heavenly bodies, it became the model for understanding the structure of the solar system. It is beyond the scope of this course to discuss all the complex social and historical implications of an Earth-centered versus a Sun-centered model of the solar system. But nearly all the early models, including Ptolemy’s version of the solar system, assumed that the Earth was the center of not only the solar system, but the entire universe. \n\nThe Ptolemaic model accounted for the apparent motions of the planets in a very direct way, by assuming that each planet moved on a small sphere or circle, called an epicycle, that moved on a larger sphere or circle, called a deferent. The stars, it was assumed, moved on a celestial sphere around the outside of the planetary spheres.

Try Googling "Ancient Egyptian Astronomy". If you're looking for stuff that old, it may be hard to find. That's prehistory, so it's either unrecorded or still in translation - if they've uncovered anything on the subject.\n\nYou might also try National Geographic's website, and perhaps your local science museum may have something as well.

The Egyptians and Babylonians decided to divide the day from sunrise to sunset into twelve parts that are called hours. They also divided the night, the time from sunset to sunrise, into twelve hours. But the day and the night are not the same length, and the length of the day and night also changes through the year

Jesus studied/knew astronomy with the elders in the temple. He would tell them things they themselves didn't know about the heavens, which is one reason they were both astounded and angered by him.\n\n  The difference is astronomy is the study of stars and the plots of planets and black holes, etc. It's scientific. Astrology is the belief that the stars and planet's alignment and movement affects our lives and rules it. Since according to Jesus's and God's teachings, God rules us all, the idea of astrology is considered tabboo by Christians and would be highly contradictory if Jesus was "learning" it.
