Working within a large geographic area, McDonald Observatory lacks the resources to send staff to present professional development workshops to teachers – and only limited numbers of teachers have the resources to attend workshops at our observatory. Our solution is the development of a new program to bring the workshop to teachers in their own communities through videoconferencing. Each workshop location has a co-facilitator who prepared for his/her duties through an orientation/training session held at McDonald Observatory. At the observatory, they experienced a variety of activities and selected the ones most suitable for the grade-levels of the teachers in their region; they recruit the teachers for the local workshop. Each videoconference session includes pre/post assessment of the participants, an interactive videoconference with an expert presenter, and assistance from the co-facilitator who manages the materials and assists with the activities. Through use of this technology, we expect to reach 500 teachers. An independent evaluator is preparing formative and summative evaluation for the project.

The view of the night sky from most of the populated regions of Earth is now seriously compromised by light pollution. An entire generation of citizens is now growing up without ever having the opportunity to gaze upon the magnificent night sky from a dark location. Much of modern astronomy involves study of faint objects, often with brightnesses similar to or fainter than the night sky. Astronomers are therefore extremely vulnerable to increases in sky brightness from light pollution. Despite their remote locations, the dark night skies over the major optical observatories are increasingly threatened by growth of artificial light at night.

Inquiry-based science education is currently receiving a consensus as a pedagogy to teach science at primary and middle school levels, with the goal to reach all children and youngsters, no matter what their future professional choices will be. By the same token, it also greatly increases the fraction of the school population in which future technicians, engineers and sciences could be recruited for further training. La main à la pâte is the name of the action undertaken by the French Académie des Sciences to develop inquiry in France, and then in many collaborating countries. The focus is on science as a whole, and not on particular disciplines such as physics, biology, and so on, since it is the understanding of scientific method and use of evidence which is at the heart of inquiry. Yet, astronomy is offering so many opportunities to demonstrate the scientific method that La main à la pâte has developed a number of inquiry activities in this field, which are presented here, such as Measuring the Earth, Calendars and cultures, the use of One Laptop per Child for Moon observations, etc.

The TENPLA project (pronounced as “ten-pla”, like a famous Japanese food “Tempura”) is designed to communicate Astronomy with the public in Japan. We have been working to suggest various ways to enjoy astronomy. We have organised star gazing parties, science cafés, and lectures. We have made many goodies which make people interested in astronomy (e.g. “Astronomical Toilet Paper”). We have also provided opportunities to communicate with each other for people who have interests in such activities. In this paper we present a broad overview of the TENPLA project.

In 2002 in the region of North-East Macedonia a site was discovered, for which archaeoastronomical analyses have shown that it encompasses all elements of an ancient observatory dated 2000 BCE. In line with the analysis the existence of a central position, from where Sunrises and rises of Full Moon were observed, was confirmed, as well as that in the rocks on the east horizon a markers were crafted marking the places of the rise of the Sun and Moon in exactly determined days. From this central position, total 9 markers can be seen on the east horizon, 3 of which used to mark the places of the Sunrise in the course of the year, and remaining 6 marked the places of Full Moon rise. By continuous monitoring of the periodicity of the Full Moon rise, ancient sky observers could develop 19 years periodic lunar calendar. In addition, on the site there is a special observation place related to the cycles of solar and lunar eclipse. Only from there and toward the east horizon 4 markers can be seen, which were used for marking the positions of the Full Moon rise on the day of the beginning of the new periodic cycle of eclipse of 54 years and 34 days. The most outstanding content on the territory of the observatory are 4 stone seats called thrones. Also, on the east horizon there is one specially crafted marker that had ritual purpose. Archaeoastronomical analysis has shown that on the day when the harvest ends, rise of Sun could be seen exactly trough the aperture of this marker, enlightening by beam only one of the thrones where most probably a community headman was sitting. That was a ritual joining of the God Sun with the community headman and renewal of his energy as a guarantee for rich harvest in the coming year. This is just a fragment of information that Megalithic Observatory Kokino has to offer, linked with the culture and cosmological presentations of people of the early agricultural community in the Bronze Age.

Astronomy as one of the oldest sciences has influenced and spurred steady development of society and culture. Inherent superstitious beliefs and their related rituals that have been hampering the progress and prosperity of nations have been dispelled and reduced considerably through the promotion of astronomical activities at all levels of the society. For disseminating basic knowledge and logic of astronomical facts that were deemed important for the development of our society, various programmes have been conducted through mass media. Many talk programmes, seminars and star parties were organised in different places. Our experiences when planning and executing such programmes are summarised and illustrated. The effectiveness of our programmes with the participation of general public is discussed in detail. Positive results of our activities that have contributed towards creation of substantial awareness of astronomy for the development of our society in Nepal are explained.

The Pierre Auger Observatory, dedicated to the detection and study of Ultra High Energy Cosmic Rays, has as one of it fundamental missions outreach activities. With this in mind, a specially conceived Visitor Center was included in the design of the Pierre Auger campus in the city of Malargüe, Mendoza, Argentina. One of its main objectives is the contact with the community, through educational courses, talks, conferences and workshops for differen t levels. The permanent exchange between the Pierre Auger scientists and teachers, professionals and society, is important to the impact of the Observatory in the vision by the community of science in general, and scientists in particular. Activities in the outreach area during the last 10 years, resulted in changes to the curricula of study in the schools. Important topics are discussed, like astronomy, light pollution control, and modification of the behavior of the local society. In this presentation we will show how an extensive outreach program, organized by scientists in contact with the community and based on (or near) a research center, can be a factor of social transformation.

En 1665, Adrien Auzout (1622-1691) figure parmi les membres des cercles scientifiques qui fleurissent en France depuis une trentaine d'années. Une comète est apparue l'année précédente et il adresse à Louis XIV son «Ephéméride du Comète» [sic] correspondant à cette voyageuse. Cette épître permet de voir combien art et science sont pour lui étroitement associés. L'observatoire Royal créé deux ans plus tard illustrera cette interaction comme le montre l'examen de ses collections.

In this talk I shall try to highlight some themes that seem to promise specially interesting progress in the coming decades. I can't claim to be much of a prophet myself, but I'd like to recall someone who was: Arthur C. Clarke. He lived in Sri Lanka, and died in 2007, aged 90. I'd like to discuss three issues that he would have found interesting: space and alien life; galaxies and their origin; and (more speculatively) the size of our universe.

The objective of this contribution is to present some results of an evaluation on the local conditions at the site that were considered in order to propose that the Observatorio Astronómico Nacional, Tonantzintla, (OAN-Tonantzintla) become a National Facility for Astronomy Education. The evaluation included a quantitative diagnostic (CCD photometry) on the quality of the local sky. The attributes of the 1-m telescope, the current instrumentation and a well planned upgrading that includes new instrumentation is considered at the basis for a successful transition maintaining the attractiveness of the site for astronomy education. A 3-year upgrading program actually in progress at UNAM is providing funding for that purpose. Physics and astronomy programs at college and graduated levels at UNAM will benefit from this, yielding clear connections among astronomy researchers and educators and students at various levels. Although the OAN-Tonantzintla faces the danger of deteriorating its sky conditions, we are maintaining awareness of the night sky characteristics in long-term monitoring campaigns and encouraging the local authorities to find alternative solutions to this problem.

Properties with a relationship to science are amongst the least represented on the UNESCO World Heritage List and the values of these properties, located in all the regions of the world, are not sufficiently recognised. The UNESCO and IAU encourage the States Parties to the World Heritage Convention to actively participate in the development and implementation of the Thematic Initiative “Astronomy and World Heritage” aiming to provide an opportunity to identify the properties connected with astronomy and for keeping their memory alive and preserving them from progressive deterioration, through the inscription of the most representative properties on the World Heritage List.

The Ciel, miroir des cultures poster-exhibition was designed by the Association Française d'Astronomie and printed in 300 copies in 2005. Each copy is composed of 14 posters introducing the different ways human beings and societies have used the sky and the heavens in history. More than three hundred cultural events have now been using the exhibition in schools and community structures as public libraries and social centres, taking place mainly in low-income urban or suburban neighbourhoods. This three-year work demonstrated the relevance of this kind of tools and events to pedagogical and social aims, specifically if the event is not limited to showing posters and also offers an opportunity for dialogue.

Since 1995, the University the Carabobo, in Venezuela, has come developing a program of astronomical popularization and learning Astronomy using the Non formal education methods. A synopsis of the activities is presented. We will also discuss some conceptual aspects about the extension of the knowledge like supplementary function of the investigation and the university teaching. We illustrate the characteristics of the communication with an example of lectures and printed material. The efficiency of the heuristic arguments could be evaluated through a ethnology study. In that order of ideas, we show some images of the activities of astronomical popularization. We can see the population and great concurrence with chronological (and cultural) heterogeneity. We conclude that the Non formal education, structured with characteristic different to the usual educational instruction, constitutes a successful strategy in the diffusion and the communicating astronomy.

One of the reasons for which this symposium has been organised is to seek answers to several questions, one of which being: Can Astronomy help reducing the waning interest that the younger generations of students feel about science studies? My personal opinion is that it is indeed the case. In fact, I claim that astronomy can be very effective for this aim. The present situation of pupil shortages in scientific studies is a complex problem because there are multiple and diverse variables influencing this situation. One of them is that the contents are not introduced in the most appropriate form, because the methods used in teaching scientific disciplines are not appropriate. This paper relates my personal experience; first as a teacher and then as a student at the Faculty of Sciences in the University of Alicante.

Ephemerides are regularly made by astronomers for their own uses. However, the general public is also interested, as well as official organisms, because of the interactions of ephemerides with society. Astronomers in charge of the making of calendars and keeping the time are of great importance every day. Their calculations are also required for the positioning of ships and airplanes. Some ephemerides are also requested by the general public.

This text outlines the main features of two educational programmes of the International Astronomical Union (IAU): the International Schools for Young Astronomers (ISYA) and the Teaching for Astronomy Development programme (TAD), developed since 1967.

The main goal of the International Schools for Young Astronomers (ISYA) is to support astronomy (education and research) in developing countries in organizing a 3-week School for students with typically M.Sc. degrees.

The context in which the ISYA were developed changed drastically during the last decade. From a time when access to large telescopes was difficult and mainly organized on a nation-basis, nowadays the archives of astronomical data have accumulated at the same time that many major telescope become accessible, and they are accessible from everywhere, the concept of virtual observatory reinforcing this access.

A second programme of the IAU, Teaching for Astronomy Development (TAD), partially based on a School, but also of shorter duration (typically one week) has a complementary objective. It is dedicated to assist countries that have little or no astronomical activity, but that wish to enhance their astronomy education. The fast development of the TAD programme over the past years is emphasized.

The observation of the sky had an important rôle among the Maya, Aztecs and other prehispanic peoples of Mesoamerica. Their familiarity with the regularities of the apparent motion of the Sun, the Moon and bright planets is attested in a large amount of astronomical data contained in codices and monumental hieroglyphic inscriptions, as well as in their sophisticated calendrical system. On the other hand, the study of architectural alignments has disclosed that civic and ceremonial buildings were largely oriented on astronomical grounds, mostly to sunrises and sunsets on certain dates, allowing the use of observational calendars that facilitated a proper scheduling of agricultural and the associated ritual activities in the yearly cycle. Both accurate knowledge and other astronomically-derived concepts reveal that the significance attributed to certain celestial events by the ancient Mesoamericans can be explained in terms of the relationship of these phenomena with specific environmental and cultural facts, such as seasonal climatic changes and subsistence strategies. It was particularly due to its practical utility that astronomy, intertwined with religious ideas and practices, had such an important place in the worldview and, consequently, in the cosmologically substantiated political ideology of Mesoamerican societies

It is argued that Copernican astronomy is a key theme in Michelangelo's fresco of the Last Judgment in the Sistine Chapel, and was incorporated with the knowledge, consent and approval of the Popes concerned. In Christian art, the iconography of the Last Judgment (depicting the three parts of the universe: heaven, Earth and hell) was traditionally based on a layered structure relating to perceptions of the flat Earth covered by the dome of heaven according to biblical cosmology. In Michelangelo's revolutionary work, Christ is significantly depicted as a beardless Apollonian Sun-god, positioned in the centre of a dramatic circular design rather than at the top of a layered format. This appears to relate to the traditional Christian analogy between the deity and the astronomical feature of the sun, the neoplatonic cult of Sun-symbolism and sources in Dante. More importantly, the influence of the Copernican theory of heliocentricity is argued, since interest in such ideas in papal circles is demonstrated at exactly the time of the commission of the painting (1533). This provides important evidence of papal support for Copernican heliocentricity as early as the 1530s.

The World at Night (TWAN) is a global program to produce, collect, and present stunning photographs and time-lapse videos of the world's most beautiful and historic sites against the night-time backdrop of stars, planets, and celestial events. TWAN is a bridge between art, science and humanity to bring the message of peace, concealed in the sky. Organised by “Astronomers Without Borders”, the project consist of world's best night sky photographers in over countries and coordinators, regional event organisers, and consultants. TWAN was also designated as a Special Project of the International Year of Astronomy 2009. While the project's global exhibitions and educational events peaked during IYA2009, TWAN is planned for long term in several phases and will continue to create and exhibit images in the next years.

To date, among the hundred or so minor planets we discovered with various instruments around the world, twenty of these objects have been definitively numbered and named. We have choosen the names according to our centers of interest. In honouring people in domains as varied as astronomy, astronautics, music, paleontology, comic strips, . . . we had the opportunity of establishing fruitful relationships with a large horizon of cultures. It was also a good opportunity for the diffusion of astronomy towards other communities.
