Analyses of Cassini imaging data with this model reveals that the moons Aegaeon, Methone and Pallene are darker than one would expect given trends previously observed among the nearby mid-sized satellites. On the other hand, the trojan moons Calypso and Helene have substantially brighter surfaces than their co-orbital companions Tethys and Dione. These observations are inconsistent with the moons' surface brightnesses being entirely controlled by the local flux of E-ring par- ticles, and therefore strongly imply that other phenomena are affecting their surface properties. The darkness of Aegaeon, Methone and Pallene is correlated with the fluxes of high-energy protons, implying that high-energy radiation is responsible for darkening these small moons. Meanwhile, Prometheus and Pandora appear to be brightened by their interactions with nearby dusty F ring, implying that enhanced dust fluxes are most likely responsible for Calypso's and Helene's excess brightness. -

The presence of water has long been seen as a key condition for life in planetary environments. The Cassini spacecraft discovered water vapour in the Saturnian system by detecting absorption of UV emission from a background star. Investigating other possible manifestations of water is essential, one of which, provided physical conditions are suitable, is maser emission. -

The Dunhuang Chinese Sky: a Comprehensive Study of the Oldest Known Star Atlas

Although partially studied by a few Chinese scholars, it has never been fully displayed and discussed in the Western world. This set of sky maps (12 hour angle maps in quasi-cylindrical projection and a circumpolar map in azimuthal projection), displaying the full sky visible from the Northern hemisphere, is up to now the oldest complete preserved star atlas from any civilisation. It is also the first known pictorial representation of the quasi-totality of the Chinese constellations. This paper describes the history of the physical object – a roll of thin paper drawn with ink. We analyse the stellar content of each map (1339 stars, 257 asterisms) and the texts associated with the maps. We establish the precision with which the maps are drawn (1.5 to 4° for the brightest stars) and examine the type of projections used. -

Universal Mythology: Stories
Universal Mythology: Stories That Circle The World Lydia L. This installation is about mythology and the commonalities that occur between cultures across the world. According to folklorist Alan Dundes, myths are sacred narratives that explain the evolution of the world and humanity. He defines the sacred narratives as “a story that serves to define the fundamental worldview of a culture by explaining aspects of the natural world, and delineating the psychological and social practices and ideals of a society.” Stories explain how and why the world works and I want to understand the connections in these distant mythologies by exploring their existence and theories that surround them. This painting illustrates the connection between separate cultures through their polytheistic mythologies. It features twelve deities, each from a different mythology/religion. By including these gods, I have allowed for a diversified group of cultures while highlighting characters whose traits consistently appear in many mythologies. It has the Celtic supreme god, Dagda; the Norse trickster god, Loki; the Japanese moon god, Tsukuyomi; the Aztec sun god, Huitzilopochtli; the Incan nature goddess, Pachamama; the Egyptian water goddess, Tefnut; the Polynesian fire goddess, Mahuika; the Inuit hunting goddess, Arnakuagsak; the Greek fate goddesses, the Moirai: Clotho, Lachesis, and Atropos; the Yoruba love goddess, Oshun; the Chinese war god, Chiyou; and the Hindu death god, Yama. The painting was made with acrylic paint on mirror. Connection is an important element in my art, and I incorporate this by using the mirror to bring the audience into the piece, allowing them to see their reflection within the parting of the clouds, whilst viewing the piece. -

Copenhaver Excerpt More information CHAPTER ONE THE SCRUPLES OF J. G. FRAZER Frazer is much more savage than most of his savages. 1 1 SCAREHORSE Where chariots raced in the stadium at Olympia, part of the track was called the Scarehorse – Taraxippos. Sometimes horses galloped past it, but sometimes they panicked, ending the race at that spot in a jum- ble of wheels and harness that no one could explain. Some said that a horse-whisperer was buried there. Some claimed that the tomb was empty, built long ago to atone for a murder. Others insisted that there was a corpse – of a man who had bad luck at racing and became a malevolent spirit ( daimona ) jealous of the riders. A man from Egypt said that Pelops got the idea to bury something there from Amphion of Thebes. This Egyptian thought that Amphion and also Orpheus from Thrace worked dreadful magic ( mageussai ) so that wild animals came to Orpheus when they chanted, and rocks built them- selves into walls for Amphion. 2 The spectators at the Games were humans – mortal men – and it was they who traded tales about the Taraxippos. -

First of all, I owe a lot of gratitude to my supervisor Dr. Rolf Strootman, whose lectures not only inspired the subject for this thesis, but whose door was always open in case I needed advice or felt the need to discuss complex topics. With his incredible amount of knowledge on the Hellenistic Period provided me with valuable insights, yet always encouraged me to follow my own view on things. Over the course of this study, there were several people along the way who helped immensely by providing information, even if it was not yet published. Firstly, Prof. Dr. Miguel John Versluys, who was kind enough to send his forthcoming book on Nemrud Dagh, an important contribution to the information on Antiochos I of Kommagene. Secondly, Prof. Dr. Panagiotis Iossif who even managed to send several articles in the nick of time to help my thesis. Lastly, the National Numismatic Collection department of the Nederlandse Bank, to whom I own gratitude for sending several scans of Hellenistic coins. -
