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. This includes, but is by no means restricted to, the development of modern scientific astronomy. This close and perpetual interaction between astronomical knowledge and its role within human culture is a vital element of the outstanding universal value of these properties. These material testimonies of astronomy, found in all geographical regions, span all periods from prehistory to today. The main goal of the meeting was to define the strategy of the thematic initiative and a methodology which will aid States Parties in identification of the sites connected with astronomy.

This web site gives access to up-to-date meteorological forecasts in order to provide astronomers with information to plan their sky observation activities. The forecasts cover North America and are produced by the numerical weather prediction models that execute at the Canadian Meteorological Centre. The following forecast parameters are available in real time: forecasts of cloud, surface winds, temperatures and humidity as well as more specific parameters such as seeing forecasts and sky transparency.
Cloud forecast Cloud forecasts at hourly intervals up to 48 hours. These forecasts can be interpreted in the same way as satellite pictures in the visible spectrum. Seeing forecast Seeing forecasts at 3-hourly intervals up to 48 hours. The “seeing” is the term used in astronomy to quantify the steadiness or the turbulence of the atmosphere.
The detailed observation of planets, planetary nebulae or any celestial object requires excellent seeing conditions. Sky transparency forecast Sky transparency forecast at hourly intervals up to 48 hours. Observing deep sky objects such as faint galaxies and nebulae requires excellent sky transparency. Astronomers evaluate sky transparency based on the magnitude of the faintest star visible to the unaided eye.

Use it to locate a planet, the Moon, or the Sun and track their movements across the sky. The map also shows the phases of the Moon, and all solar and lunar eclipses. Need some help? Mercury is just 11 degrees from the Sun in the sky, so it is difficult to see. Venus can best be seen in the hours just before sunrise. Visibility deteriorates as the sky gets brighter.
8 ASTRONOMICAL DATING OF ABORIGINAL ASTRONOMY. There are several ways in which astronomical phenomena could in principle be used to date a site.
Come take part in a community discussion to reflect on the state of the profession and envision how to improve it into the s. Information about important dates, logistics, and accessibility will be posted at the IA2 website. Registration and abstract submission are expected to open by the end of June. Questions can be directed to Inclusion2 stsci. It has been four years since the Nashville Inclusive Astronomy meeting, an event that brought astronomers together with sociologists, policy makers, and leaders in the field to discuss issues affecting underrepresented groups in astronomy.
The Nashville Recommendations , which emphasize equity and intersectionality, build upon a rich history of work to broaden participation and improve climates. We now have the opportunity to bring together the astronomy community to discuss the current state of the profession and make recommendations for the s and beyond. Specifically, we will discuss community expectations on inclusivity and representation, evaluate our progress towards meeting equity goals, and address the needs of marginalized groups in the workforce.
Astronomers have discovered thousands of planets circling distant stars. This is the hottest field in astronomy. How do you find exoplanets and what are they like? Have we discovered a Second-Earth?

With a few swipes of your finger, these apps can help you identify objects, take you on a tour of the night sky and even plan your stargazing for that upcoming holiday. Whatever your level of interest in astronomy — from casual stargazer to professional astronomer — there is likely an app to suit you. In this edition of Mobile Stargazing, we’ll focus on sky-charting apps — mobile star atlases loaded with features that run circles around stuffy old paper atlases.
There are many to choose from, at a range of prices. Let’s look at how sky-charting apps work, how to set them up and what to consider when you’re browsing the App Store or the Google Play store. The stars, and the deep-space objects outside our solar system , are so distant that they effectively appear fixed in place with respect to one another, and this has allowed maps of the sky to be created.
Over time, the star patterns that ancient skywatchers first imagined have become standardized into 88 modern constellations that completely cover the sky. Each one has a fixed boundary, with no gaps or overlap, so everything in the sky can be indexed to a particular constellation. The regular motions of the Earth’s rotation every 24 hours and the planet’s orbit around the sun every The same stars are overhead at the same time on the same date every year. And where you are located on the Earth determines which constellations are in your sky, too.
After all, the midnight sky for a stargazer in the Southern Hemisphere will be much different from that of a skywatcher in the Northern Hemisphere, even within the same time zone. That’s why astronomers take vacations! Solar system objects — such as Earth’s moon, the planets, comets and asteroids — move constantly, in a predictable way, so these are handled by algorithms in the app that know the objects’ orbital parameters, and therefore can accurately predict where they will be at any given time — past, present or future.

Plenty of Fish. Use this astronomy to figure it out. But sometimes, awesome can use a bit of cost in the dating girl. Not because there’s no one out there nerds are.
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.
It is frighteningly easy, then, to fit a star and a date fortuitously and made all the easier when we consider that only rarely does one single alignment at a particular monument stand out as the obvious astronomical candidate. In order to be fair with the data—one of the most fundamental methodological principles—we should consider all possible alignments. If we are willing to postulate as some people have done that structures were aligned upon the point of appearance or disappearance of a star rather than its actual rising and setting point, it increases the chances of our being able to fit a date and star fortuitously to any given alignment especially at high latitudes, where the astronomical bodies rise and set at a fairly shallow angle.
Overall, the potential for circular argument is obvious.
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.

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.
As an influential institution that was not devoted solely to astronomy, the Maragha Observatory revived advanced scientific studies during what is normally considered the period when science declined in Islam. Ideas initiating from the Maragha School impacted well beyond the Islamic territories and influenced the astronomical revolution of the 16th century. The observatory site before top and after bottom the first stage of excavation. Model replica of the observatory site. Bottom: Auxiliary observational sites close to the main building of the observatory.
The central structure, which is assumed to be the main building of the observatory, is circular. Its diameter is 22m and the base of its enclosing wall is 80 cm thick. On each side of the central corridor are 6 rooms, the pair at each end being smaller than the rest. Outside the main building towards the south, south-east and north-east are five circular constructions. These were the places where the smaller observational instruments were once mounted.
