This Initiative offers to the States Parties a possibility to evaluate and recognize the importance of this specific heritage, in terms of enrichment of the history of humanity, the promotion of cultural diversity and the development of international exchanges. It provides an opportunity not only to identify the sites connected with astronomy but also of keeping their memory alive and preserving them from progressive deterioration, through the through inscription on the World Heritage List of the most representative properties. The sky, our common and universal heritage, forms an integral part of the total environment that is perceived by mankind. Including the interpretation of the sky as a theme in World Heritage is a logical step towards taking into consideration the relationship between mankind and its environment. This step is necessary for the recognition and safeguarding of cultural properties and of cultural or natural landscapes that transcribe the relationship between mankind and the sky. Properties relating to astronomy stand as a tribute to the complexity and diversity of ways in which people rationalised the cosmos and framed their actions in accordance with that understanding.

History of astronomy

An aerial view of the observatory site. Tehran: Amirkabir Publications, The Maragha Observatory has a unique place in the history of medieval astronomy. It represents a new wave of scientific activities in the Islamic world in the mid 13th century, it had a key role in the development of some sophisticated pre-Copernican non-Ptolemaic systems for explaining the planetary motions, and it was the model for several observatories that were built in Persia, Transoxiana, and Asia Minor up to the 17th century.

Is it possible to date an archaeological site by astronomical means? In theory, the answer is yes, for if we can identify an alignment and the intended astronomical target, measure where the alignment points, and then use modern astronomy to calculate where that event occurred at different times in the past, then we can fit the best date to the alignment. Stellar alignments would seem to be most promising, because the rising and setting positions of most stars change significantly over the centuries owing to precession.

The rising and setting position of the sun at the solstices and the moon at the standstill limits also alter with time, although by much less, owing to the slow change in the obliquity of the ecliptic. In practice, however, astronomical dating is rife with pitfalls. The main one is that we rarely have reliable e. Where we do have historical evidence, we are likely to know the date fairly accurately already. More often, we are dealing with prehistoric structures where we have no evidence other than the alignments themselves.

If we find an alignment that we suspect to be stellar, we can try different stars and different dates to see if any combination fits particularly well. The problem here is that if, say, we are willing to consider the fifteen brightest stars and a five-hundred-year date range, then there is approximately a one-in-three chance that we will be able to find a star and a date to fit any alignment.

The stars have always fascinated mankind. Telescopes aren’t exactly cheap though, so how do you know which ones are worth the money? Where do you find charts that show you which stars are which? How do you know when the weather will be best suited for viewing?

A new dating method for stars, based on the radioactive decay of isotopes of uranium and thorium, has refined the estimates of the age of the Milky Way and added weight to the argument that the structure of the universe was established very soon after the Big Bang.

This astronomy calendar of celestial events contains dates for notable celestial events including moon phases , meteor showers , eclipses , oppositions , conjunctions , and other interesting events. Most of the astronomical events on this calendar can be seen with unaided eye, although some may require a good pair of binoculars for best viewing. Many of these events and dates used here were obtained from the U.

Events on the calendar are organized by date and each is identified with an astronomy icon as outlined below. Please note that all dates and times are given in Coordinated Universal Time UTC must be converted to your local date and time.

Its activities will include establishing a worldwide network of National Astronomy Education Coordinators NAECs , promoting astronomy in national curricula, supporting teachers with evidence-based education research and helping the community with its professional development. The OAE is also intended to facilitate discussion and knowledge sharing within the community, particularly between astronomy education researchers and astronomy education practitioners.

For instance, common language errors that we only see at times are not included in the explanations because they are explained in other general grammars, dictionaries, and handbooks. The LEs strive for consistency in editing those MSs selected for language editing. Nevertheless, there will always be variations in the English found in the Journal as a whole.

This occurs because there is often more than one way to construct a phrase or sentence or even to correct a grammar problem. This includes the following:. Also see Sect. We ask that the cardinal endings be left off for dates because it is informal style and that the month be written out, since is ambiguous between cultures, and it too is informal inside the text. Since abstracts are supposed to be self-contained, LEs suggest substituting most citations of earlier work with other wording.

The required sections are Aims, Method, and Results, even if you choose not to use the headings. If the content of a section is missing or if it contradicts the headings, LEs point it out and suggest an adjustment. We also adjust the caption to resemble the expected style: e. These include.
