Die Astronomie gilt als eine der ältesten Wissenschaften. Ihre Anfänge liegen im Nachdenken über die Himmelserscheinungen, in der kultischen Verehrung der Gestirne und im Erarbeiten von Kalender bzw. Zeitbestimmung.In einem jahrtausendelangen Prozess - besonders gut erkennbar in der Himmelskunde Mesopotamiens und Griechenlands - trennten sich zunächst Astronomie und (Natur. Astronomy (from the Greek astron (ἄστρον) meaning star and nomos (nόμος) meaning law) is the scientific study of celestial bodies such as stars, planets, comets, and galaxies . The objects studied include stars, galaxies, planets, moons, asteroids, comets and nebulae.Phenomena outside the Earth's atmosphere are also studied. That includes supernovae explosions, gamma ray bursts. (double-click any word to see its definition) Introduction. If you think the answer to this question is obvious, think again. The best minds of physics have studied this question for over a century, and the current answer may surprise you. In 1826, the astronomer Heinrich Olbers asked, Why is the sky dark at night?.

Welcome to the Encyclopedia of Astronomy and Astrophysics. This unique resource covers the entire field of astronomy and astrophysics and this online version includes the full text of over 2,750 articles, plus sophisticated search and retrieval functionality, links to the primary literature, and is frequently updated with new material Theoretical astronomers use several tools including analytical models and computational numerical simulations; each has its particular advantages. Analytical models of a process are better for giving broader insight into the heart of what is going on. Numerical models reveal the existence of phenomena and effects otherwise unobserved.
Une étoile est une boule massive et lumineuse de plasma liée par sa propre gravité dont le diamètre et la densité sont tels que la région centrale, le cœur, atteint la température. Greek Astronomy after Aristotle Apart for a few exceptions, the general consensus among Greek astronomers was that the universe was earth-centred. During the 4th century BCE, Plato and Aristotle agreed on a geocentric model but both thinkers did so based on mystical arguments: The stars and planets were carried around the earth on spheres. Fundamental to the structure of the Universe is the existence of dark matter and dark energy. These are now thought to be its dominant components, forming 96% of the mass of the Universe. For this reason, much effort is expended in trying to understand the physics of these components.

Introductory Astronomy: Ellipses (And you'd better not confuse ellipses with eclipses!) Kepler's first law is that planets orbit on ellipses with the sun at one focus. An ellipse is (sort of) an oval shape, with two interior points called foci (singular: focus), a long axis (the major axis), a short axis (the minor axis), and a center (which.

An ellipse is defined as the locus of all points in the plane for which the sum of the distances r1 and r2 to two fixed points F1 and F2 (called the foci) separated by a distance 2c, is a given constant 2a. Therefore, from this definition the equation of the ellipse is: r1 + r2 = 2a, where a = semi-major axis. [ Atmospheric Refraction Applet Apparent Flattening of the Sun. The true elevation angles of the Sun are not corrected for atmospheric refraction, which is bending the light while passing through the Earth's atmosphere. The effect of refraction depends on atmospheric conditions (pressure, temperature, relative humidity) and on the wavelength NOAO is the national center for ground-based nighttime astronomy in the United States and is operated by the Association of Universities for Research in Astronomy (AURA). under cooperative agreement with the National Science Foundation.

A scholarly legal publication containing all the law relating to a particular area, such as Criminal Law or Land-Use Control.. Lawyers commonly use treatises in order to review the law and update their knowledge of pertinent case decisions and statutes During the Renaissance, Nicolaus Copernicus proposed a heliocentric model of the solar system. His work was defended by Galileo Galilei and expanded upon by Johannes Kepler. Kepler was the first to devise a system that correctly described the details of the motion of the planets around the Sun. However, Kepler did not succeed in formulating a theory behind the laws he wrote down. It was Isaac Newton, with his invention of celestial dynamics and his law of gravitation, who finally explained the motions of the planets. Newton also developed the reflecting telescope. Cosmology (from the Greek κόσμος (kosmos) "world, universe" and λόγος (logos) "word, study" or literally "logic") could be considered the study of the Universe as a whole.
Research Interests. Alex Filippenko and his collaborators are determining the nature of the progenitor stars and the explosion mechanisms of different types of supernovae and gamma-ray bursts In early historic times, astronomy only consisted of the observation and predictions of the motions of objects visible to the naked eye. In some locations, early cultures assembled massive artifacts that possibly had some astronomical purpose. In addition to their ceremonial uses, these observatories could be employed to determine the seasons, an important factor in knowing when to plant crops and in understanding the length of the year.

The discipline is an overlap of astronomy and chemistry. The word "astrochemistry" may be applied to both the Solar System and the interstellar medium. The study of the abundance of elements and isotope ratios in Solar System objects, such as meteorites, is also called cosmochemistry, while the study of interstellar atoms and molecules and their interaction with radiation is sometimes called molecular astrophysics. The formation, atomic and chemical composition, evolution and fate of molecular gas clouds is of special interest, because it is from these clouds that solar systems form.
aberration: the apparent angular displacement of the observed position of a celestial object from its geometric position, caused by the finite velocity of light in combination with the motions of the observer and of the observed object. Annual aberration is due to the motion of the Earth around the Sun, while diurnal aberration is due to the Earth's rotation Difference between astrology and astronomy in the simplest form is this; astronomy is a science while astrology is considered a pseudo-science by modern scientists. However, we can all accept that astronomy and astrology are similar looking words that are also somewhat related The International Astronomical Union (IAU) was founded in 1919. Its mission is to promote and safeguard the science of astronomy in all its aspects, including research, communication, education and development, through international cooperation

Observations of the large-scale structure of the Universe, a branch known as physical cosmology, have provided a deep understanding of the formation and evolution of the cosmos. Fundamental to modern cosmology is the well-accepted theory of the Big Bang, wherein our Universe began at a single point in time, and thereafter expanded over the course of 13.8 billion years to its present condition. The concept of the Big Bang can be traced back to the discovery of the microwave background radiation in 1965. Astronomy.
