After discovering Uranus in 1781, William Herschel opened new areas of research in 1800 by discovering infrared radiation - a type of light that is not visible to the human eye. The Andromeda Galaxy was first described in his book The Book of Fixed Stars. One of these star clusters For example, when two researchers at the University of Utah announced in 1989 that they had discovered a way to achieve nuclear fusion (the process that powers the stars) at room temperature, other scientists at more than 25 laboratories around the United States attempted to duplicate cold fusion within a few weekswithout success, as it turned out. CAIRO (Reuters) -A hidden corridor nine metres (30 feet) long has been discovered close to the main entrance of the 4,500-year-old Great Pyramid of Giza, and this could lead to further findings, Egyptian antiquities officials said on Thursday.

The initiations in India were even more ancient. Each of these wandering stars was thought to have an "unmoved mover" the entity that makes it move through the heavens. Rest was thus generally regarded as the natural state of matter. He began with several assumptions that were common in his time, such as the idea that the motions of the heavenly bodies must be made up of combinations of uniform circular motions. It is said to be the earliest known preserved star map in the world which dates back before AD 700. Copernicus wanted to develop an improved theory from which to calculate planetary positions, but in doing so, he was himself not free of all traditional prejudices. progression in the evolution of a world.

As Earth was demoted from its position at the center of the universe, so, too, was humanity. Astronomers such as Eudoxus (contemporary with Plato) observed planetary motions and cycles, and created a geocentric cosmological model that would be accepted by Aristotle. In this sense the book is a tool one can use to predict the locations of the stars Compared to earlier astronomy the book is much more focused on serving as a useful tool than as presenting a system for describing the nature of the heavens. His measurement was just off by two minutes; a level of accuracy that has never been attained. Similar to astrology, astronomy also originated thousands of years ago, and that is why the two fields of study are confused and often equated with the same thing. the Greek astronomers, Aristarchus presented evidence that the earth and The night skies & astronomical bodies have been a source of wonder & speculation since the development of early civilizations.
