the Webfooted Astronomer Seattle Astronomical Society • September 2003 Sept. Meeting: September Meeting Galaxy Formation in Speaker: Vandana Desai Rich Clusters Galaxy Formation Vandana Desai grew up in Chicago, in Rich Clusters majored in Astronomy at Caltech in Pasadena, CA, then came directly to Wednesday, September 17 graduate school at the UW, where 7:30 p.m. she is working with Professor Physics-Astronomy Building Julianne Dalcanton. Ms. Desai is Room A102 interested in all topics related to University of Washington galaxy formation and evolution, but Seattle has concentrated her efforts on how galaxies evolve in clusters. Come early at 7 p.m. for coffee and snacks and to visit with your In order to understand this evolu- fellow members! tion, Ms. Desai uses both space- based imaging data as well as numerical simulations. She’ll show examples of both during her talk in September about galaxy formation in rich clusters. She will give a basic description of how galaxies are expected to form if the mass of the Uni- verse is dominated by Cold Dark Matter, and will then discuss how the evolution of a galaxy is affected by its environment, focusing on clusters of galaxies. These are active areas of research at the University of Washing- ton, so she will show us some work in progress, including an extremely high-resolution numerical simulation of galaxies forming within a cluster and new Hubble Space Telescope images of clusters at high redshift.

In This Exercise, You Will Learn Some of the Stars That Make up Patterns in the Sky
PHYS 1830 - Perspectives on the Universe Winter 2015 PLANETARIUM EXERCISE In this exercise, you will learn some of the stars that make up patterns in the sky. These are properly known as asterisms. Constellations, on the other hand, are defined as 88 regions or patches of sky that are officially designated by the International Astronomical Union (IAU). Constellations often contain the familiar patterns of stars that are the asterisms, but constellations are usually identified by their Latin name. For example, the asterism of the Big Dipper is contained within the constellation of Ursa Major, the Greater Bear. You will also be introduced to the astronomical coordinate system that is most commonly used to describe positions of objects in the sky: the equatorial coordinate system. Part 1: Sketching You will sketch several asterisms on a single page. Draw a line across the bottom of the page to indicate the position of the horizon. Label this line with the cardinal points. Draw a cross near the top of your sketch to represent the position of the zenith. Label this point. Lightly draw in the position of the meridian and label it. For each sketch, label the time for which the planetarium is set and record your location within the dome. Use circles to mark the relative positions of the stars. The size of the circle should reflect the relative brightness with larger circles indicating brighter stars. Use straight lines to connect the relevant stars to draw the asterism shape. Sketch #1: Big Dipper, Little Dipper, and Cassiopeia Label the asterism/constellation name. -

Asterism and Constellation: Terminological Dilemmas
www.ebscohost.com www.gi.sanu.ac.rs, www.doiserbia.nb.rs, J. Geogr. Inst. Cvijic. 67(1) (1–10) Original scientific paper UDC: 521/525 DOI: https://doi.org/10.2298/IJGI1701001P ASTERISM AND CONSTELLATION: TERMINOLOGICAL DILEMMAS Zorica Prnjat *1, Milutin Tadić * * University of Belgrade, Faculty of Geography, Belgrade, Serbia Received: March 14, 2017; Reviewed: March 23, 2017; Accepted: March 31, 2017 Abstract: In contemporary astronomical literature, there is no uniform definition of the term asterism. This inconsistency is the consequence of differences between the traditional understanding of the term constellation, from the standpoint of the naked eye astronomy, and its contemporary understanding from the standpoint of the International Astronomical Union. A traditional constellation is a recognizable star configuration with a well-established name, whereas the International Astronomical Union defines a constellation as an exactly defined sector of the cosmic space that belongs to a particular traditional constellation. Asterism is a lower rank term in comparison to constellation, and as such it may not denote a whole traditional constellation, as these terms would become synonymous and parts of constellations would become “asterisms of asterisms“. Similarly, asterism cannot define a macro configuration composed of the brightest stars in more constellations, thus, the Summer Triangle and other sky polygons are not asterisms. Therefore, asterisms are neither constellations nor sky polygons, but the third – easily recognizable parts of traditional constellations with historically well-established names, including separate groups of smaller stars that belong to star clusters (autonomous asterisms). Forms and names of asterisms may or may not be consistent with the parent constellation, and accordingly asterisms can be divided into compatible and incompatible. -

Alternate Constellation Guide
ARKANSAS NATURAL SKY ASSOCIATION LEARNING THE CONSTELLATIONS (Library Telescope Manual included) By Robert Togni Cover Image courtesy of Wikimedia. Do not write in this book, and return with scope to library. A personal copy of this guide can be obtained online at www.darkskyarkansas.com Preface This publication was inspired by and built upon Robert (Rocky) Togni’s quest to share the night sky with all who can be enticed under it. His belief is that the best place to start a relationship with the night sky is to learn the constellations and explore the principle ob- jects within them with the naked eye and a pair of common binoculars. Over a period of years, Rocky evolved a concept, using seasonal asterisms like the Summer Triangle and the Winter Hexagon, to create an easy to use set of simple charts to make learning one’s way around the night sky as simple and fun as possible. Recognizing that the most avid defenders of the natural night time environment are those who have grown to know and love nature at night and exploring the universe that it re- veals, the Arkansas Natural Sky Association (ANSA) asked Rocky if the Association could publish his guide. The hope being that making this available in printed form at vari- ous star parties and other relevant venues would help bring more people to the night sky as well as provide funds for the Association’s work. Once hooked, the owner will definitely want to seek deeper guides. But there is no better publication for opening the sky for the neophyte observer, making the guide the perfect companion for a library telescope. -

Talafha ([email protected]) ABSTRACT In the past, the Arabs in Al-hara Zone used many stars to deduce the seasons of the year and also to deduce the roads, at that time this was the most convienent way to figure their ways and to know the time of the year they have to travel or to planet, The most important used stars at that time were the Pleiades, Canopus, Arcturus and other stars. This study shows the inscriptions found in Al-hara Zone in many field trips in the year 2018 which were written on smooth black rocks and how these inscriptions related to the stars and to the seasons – at that time - of the year.

Introduction the Constellations of the Winter
Introduction The winter sky is an excellent place to begin exploring the constellations that make up the night sky. Orion is the key, or signpost, for locating many of the other constellations in the winter sky. There are two convenient ways to locate all of the main constellations around Orion once Orion is located. Fortunately, Orion is easy to locate and well known to most people. The first way is to follow lines made by pairs of stars in Orion. The second way is to locate the great winter Orion is the key for hexagon of bright star around Orion. cracking the winter sky. The Constellations of the Winter Sky If you live in the northern latitudes and you scan the sky from the southern horizon to the region overhead, you should be able to see the following constellations on a clear winter night: Orion the Hunter, Canis Major the Great Dog, Canis Minor the Little Dog, Taurus the Bull, Auriga the Charioteer, Gemini the Twins and the Pleiades star cluster. (See the map on the next page). In Greek mythology, Orion was a great hunter who eventually offended the gods, especially Apollo. Apollo tricked Artemis, the Goddess of the hunt, into shooting Orion on a bet. When she discovered that she had shot Orion, she quickly lifted him to the heavens and made him immortal, where he now hunts eternally with his two dogs, Canis Major and Canis Minor. In front of him is his prey Taurus the Bull. The myths surrounding Auriga the Charioteer vary, but it is an ancient constellation dating back to at least to the Ancient Greeks.
