Orion's Constel

The distinction between astronomy and astrophysics has largely evaporated. As stated in the McGraw-Hill Multimedia Encyclopedia of Science and Technology, the older view that astronomers study objects in the sky as astrophysicists seek to explain then has been superseded. The new broadening of astronomy is illustrated by the use of chemical knowledge and methods in studying molecules in interstellar clouds; the use of geological knowledge and met

after he had had too much wine, he stumbled off and tried to take the lay by force. For this the king had Orion blinded and banished from his realm. In his blind state Orion sought the aid of Hephaestus, the God of the Forge, and eventually the healing rays of the sun restored his sight. The next story is called “Chasing the Pleiades” – In another story, Orion fell in love with Pleiades; some say that it was the mother of the Pleiades whom Orion loved. Her name was Pleione. The story has it that Zeus snatched up the Seven Sisters who are the Pleiades and placed them in the sky where Orion still pursues them. Another story that is a different version of the myth is called “The Fatal Scorpion” – Myth has it that Orion was killed by the sting of a Scorpion. The Scorpion is identified with the constellation of Scorpius, halfway around the sky from Orion. Some say that the Scorpion was sent by the Gaia the Goddess of the Earth; others say it was Artemis, the Goddess of the!

Although astronomy and astrophysics are very close, Astronomy, in itself, has a many divisions. As stated in the McGraw-Hill Multimedia Encyclopedia of Science and Technology, these divisions include stellar astronomy, the study of the stars, especially through observations of the intensity of the light and it’s variation and stellar spectra, interstellar astronomy, the study of interstellar space, especially the hydrogen gas and the molecules observed there, galaxies, which can now be studied principally by spectroscopy, with new techniques such as those described above, cosmology, mapping of the distance to thousands of galaxies has enabled three-dimensional maps of regions of space to be made the structure of space must be interpreted in models of galaxy formation. The other divisions are solar physics which the study of the sun, traditionally known as solar physics rather than solar astronomy, treats it not only as an individual object close enough to study in detail but also as a prototype of more distant stars. The next division is the solar-system astronomy, which tells us that the planets can be studied with telescopes from the ground, from spacecraft in the earth’s orbit. And from space craft passing near them or landing on them, also another division is the search for extraterrestrial life which is a serious observation that are being made or are proposed for searches for signs of celestial signals being sent by extraterrestrial beings. The last few divisions which are astrometry, the study of the positions and motions of stars and other celestial objects, telescopes that new technologies have led to advances in telescopes in all parts of the spectrum, computational astronomy which is the small and moderate sized computers that run telescopes and assist with data reduction. Finally there is the Celestial mechanics which is another topic that remains traditionally part of astronomy rather than astrophysics and is modern celestial mechanics, which became prominent in such matters as predicting the path of Haley’s Comet with sufficient accuracy to allow space craft rendezvous, and the last division which is the historical astronomy which is the study of astronomy’s rich history that not only enables the roots of the science to be better understood but also provides data for comparison with the present.

hods in analyzing the origin and evolution of life on the earth and in the search for extraterrestrial life. Astronomy has been transformed by new technology, notably electronics. Computers are integral to most astronomical research, both observational and theoretical. Electronic devices have transformed observation. For example, the use of electronic chips known as charge-coupled devises as detectors and of optical fibers to carry stellar images to spectrograph slits as reduced the time needed to determine the redshift of many galaxies from perhaps 8 h to about 1 min. This factor of 500 has led to a qualitative c
