This is a condensed version of the Fab Fifty Presentation on January 19, 2018 TAAS Fabulous Fifty A program for those new to astronomy Friday Evening, January 19, 2018, 1900 MST (7 pm) All TAAS and other new and not so new astronomers are welcome. What is the TAAS Fabulous 50 Program? It is a set of 4 meetings events spread across a calendar year in which a beginner to astronomy learns to locate 50 of the most prominent night sky objects visible to the naked eye. These include stars, constellations, asterisms, and Messier objects. Methodology 1. Meeting dates for each season in year 2018 Winter Jan 19 Spring Apr 20 Summer Jul 20 Fall Oct 19 2. Locate the brightest and easiest to observe stars and associated constellations 3. Add new prominent constellations for each season Tonight’s Schedule 7:00 pm – We meet inside for a slide presentation overview of the winter sky. 7:45 pm – View night sky outside Remember coffee, warmth, & snacks in the Kitchen The Winter Midnight Sky Over London January 15, 1869 January 15 The Midnight Sky: Familiar Notes on the Stars and Planets, Edward Durkin, 1869 January 15 The Midnight Sky: Familiar Notes on the Stars and Planets, Edward Durkin, 1869 A Good Way to Start – Find North Polaris North Star Alcor - Mizar Polaris is about the 50th brightest star.

Image from The Astronomical Companion, Guy Ottewell, 1981 Ancient Constellation Modern Constellation Vincenzo Coronelli IAU and Sky & Telescope Magazine 1681-1683 What is a Asterism? An asterism is prominent pattern or group of stars, typically having a popular name but smaller than a constellation. Ursa Major The Great Bear Big Dipper Asterism Recognizing the Constellation Orion If you spot three bright stars in a row in the winter evening, you might realize, "Oh! That's part th of Orion!" 11 brightest Suddenly, the rest of the constellation falls into place. "There's BETELGEUSE in Orion's left shoulder and RIGEL is his foot." 8th brightest Once you recognize Orion, remember that his hunting dogs are following him. Procyon is bright star in the constellation Canis Minor, THE LITTLE DOG. Sirius is in the bright star in the constellation Canis Major, THE BIG DOG.

Her encouragement, guidance, and perspective helped me navigate many a challenging problem, and my conversations with her were a consistent source of positivity and learning throughout my time at Caltech. I leave graduate school a better scientist and person for having her as a role model. Heather fostered a wonderfully positive and supportive environment for her students, giving us the space to explore and grow - I could not have asked for a better advisor or research experience. I would also like to thank Konstantin Batygin for enthusiastic and illuminating discussions that always left me more excited to explore the result at hand. Thank you as well to Dimitri Mawet for providing both expertise and contagious optimism for some of my latest direct imaging endeavors. Thank you to the rest of my thesis committee, namely Geoff Blake, Evan Kirby, and Chuck Steidel for their support, helpful conversations, and insightful questions. I am grateful to have had the opportunity to collaborate with Brendan Bowler. His talk at Caltech my second year of graduate school introduced me to an unexpected population of massive wide-separation planetary-mass companions, and lead to a long-running collaboration from which several of my thesis projects were born.

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

    25/02/09JAHH/v4 1 THE DUNHUANG CHINESE SKY: A COMPREHENSIVE STUDY OF THE OLDEST KNOWN STAR ATLAS JEAN-MARC BONNET-BIDAUD Commissariat à l’Energie Atomique ,Centre de Saclay, F-91191 Gif-sur-Yvette, France E-mail: [email protected] FRANÇOISE PRADERIE Observatoire de Paris, 61 Avenue de l’Observatoire, F- 75014 Paris, France E-mail: [email protected] and SUSAN WHITFIELD The British Library, 96 Euston Road, London NW1 2DB, UK E-mail: [email protected] Abstract: This paper presents an analysis of the star atlas included in the medieval Chinese manuscript (Or.8210/S.3326), discovered in 1907 by the archaeologist Aurel Stein at the Silk Road town of Dunhuang and now held in the British Library. 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.

    Thanet Astronomy Group Astronomy for Everyone in Plain English What to see December 29th Constellation (Orion) Stars (Betelguese, Bellatrix, Alnitak, Alnilam, Mintaka, Rigel, Saiph,) Asterism (The Winter Triangle) Stars (Betelguese, Sirius, Procyon) November to March the constellation Orion the Hunter is at its best. There are some 20 prominent stars in this constellation. The brightest and more easily observed stars are the 8 in the main body. The other stars form Orion's right arm with club, and a slain animal in his left hand. These stars are dimmer and difficult to see due to light pollution. At 8:00pm Looking South East at 119° up to 30° you see the star Betelguese, the top left corner of Orion, a red super giant, more than 1½ billion kms in diameter. Look at 127° up to 33° you see the star Bellatrix, the top right corner of Orion, at 8½ million kms in diameter. Look at 128° down to 24° you see Alnitak, the first of three stars side by side, forming Orion's belt. Alnitak, Alnilam (at 128° 25°) and Mintaka (at 129° 26°). Probably one of the more easily recognised groups of stars in this area of sky. Look at 137° down to 21° you see the star Rigel, the bottom right corner of Orion. A blue/white super giant, 108 million kms in diameter. Look at 130° down to 16° you see the star Saiph the bottom left corner of Orion, nearly 31 million kms in diameter.

(Mirametrics) What are Messier Objects? • Messier objects are a list of astronomical sources compiled by Charles Messier, an 18th and early 19th century astronomer. He created a list of distracting objects to avoid while comet hunting. This list now contains over 110 objects, many of which are the most famous astronomical bodies known. The list contains planetary nebula, star clusters, and other galaxies. - Bobby Martinez The Telescope The telescope used to take these images is an Astronomical Consultants and Equipment (ACE) 24- inch (0.61-meter) Ritchey-Chretien reflecting telescope. It has a focal ratio of F6.2 and is supported on a structure independent of the building that houses it. It is equipped with a Finger Lakes 1kx1k CCD camera cooled to -30o C at the Cassegrain focus. It is equipped with dual filter wheels, the first containing UBVRI scientific filters and the second RGBL color filters. Messier 1 Found 6,500 light years away in the constellation of Taurus, the Crab Nebula (known as M1) is a supernova remnant. The original supernova that formed the crab nebula was observed by Chinese, Japanese and Arab astronomers in 1054 AD as an incredibly bright “Guest star” which was visible for over twenty-two months. The supernova that produced the Crab Nebula is thought to have been an evolved star roughly ten times more massive than the Sun.

    Constellations with Prominent Stars That Can Be Found Near the Meridian at 10 Pm on January 15

    ONSTELLATIONS C Altitude Ruler The rotation of the Earth on its axis causes the stars to rise and set each evening. In addition, the orbit of the Earth around the Sun places different regions of the sky in our Horizon night-time view. The PLANISPHERE is an extremely useful tool for finding stars and 10 constellation in the sky, depicting not only what is currently in the sky but it also allows the 20 prediction of the rising and setting times of various celestial objects. 30 THE LAYOUT OF THE PLANISPHERE 40 50 The outer circumference of the dark blue circular disk (which is called the star wheel) you’ll notice that the wheel is divided into the 12 months, and that each month is divided into 60 individual dates. The star wheel rotates about the brass fastener, which represents the 70 North Celestial Pole. The frame of the planisphere has times along the outer edge. 80 Holding the planisphere on the southern corner you'll see "midnight" at the top. Moving Zenith counterclockwise, notice how the hours progress, through 1 AM, 2 AM, and so on through "noon" at the bottom. The hours then proceed through the afternoon and evening (1 PM, 2 PM, etc.) back toward midnight. Once you have the wheel set properly for the correct time and day, the displayed part represents what you see if you stand with the star and planet locator held directly over your head with the brass fastener toward the north. (Notice that the compass directions are also written on the corners of the frame.) Of course, you don't have to actually stand that way to make use of the Star and Planet Locator--this is just a description to help you understand what is displayed.

    CONSTELLATION BOÖTES, the HERDSMAN Boötes Is the Cultivator Or Ploughman Who Drives the Bears, Ursa Major and Ursa Minor Around the Pole Star Polaris

    CONSTELLATION BOÖTES, THE HERDSMAN Boötes is the cultivator or Ploughman who drives the Bears, Ursa Major and Ursa Minor around the Pole Star Polaris. The bears, tied to the Polar Axis, are pulling a plough behind them, tilling the heavenly fields "in order that the rotations of the heavens should never cease". It is said that Boötes invented the plough to enable mankind to better till the ground and as such, perhaps, immortalizes the transition from a nomadic life to settled agriculture in the ancient world. This pleased Ceres, the Goddess of Agriculture, so much that she asked Jupiter to place Boötes amongst the stars as a token of gratitude. Boötes was first catalogued by the Greek astronomer Ptolemy in the 2nd century and is home to Arcturus, the third individual brightest star in the night sky, after Sirius in Canis Major and Canopus in Carina constellation. It is a constellation of large extent, stretching from Draco to Virgo, nearly 50° in declination, and 30° in right ascension, and contains 85 naked-eye stars according to Argelander. The constellation exhibits better than most constellations the character assigned to it. One can readily picture to one's self the figure of a Herdsman with upraised arm driving the Greater Bear before him. FACTS, LOCATION & MAP • The neighbouring constellations are Canes Venatici, Coma Berenices, Corona Borealis, Draco, Hercules, Serpens Caput, Virgo, and Ursa Major. • Boötes has 10 stars with known planets and does not contain any Messier objects. • The brightest star in the constellation is Arcturus, Alpha Boötis, which is also the third brightest star in the night sky.

It consists of a humorous 24-minute show and educator’s package. The Orion Educator’s Guide is designed for Planetarians, Teachers, and parents. The information is researched, organized, and laid out so that the educator need not spend hours coming up with lesson plans or labs. This has already been accomplished by certified educators. The guide is written to alleviate the fear of space and the night sky (that many elementary and middle school teachers have) when it comes to that section of the science lesson plan. It is an excellent tool that allows the parents to be a part of the learning experience. The guide is devised in such a way that there are plenty of visuals to assist the educator and student in finding the Winter constellations.
