  • The Summer Sky by Dr
    The Summer Sky by Dr. Whitney Shane, MIRA’s Charles Hitchcock Adams Fellow Fixed Stars Some years ago this column had occasion to discuss planetary nebulae, using the Ring Nebula in Lyra, everyone’s favorite, as an example. The simple morphology of the Ring Nebula makes it ideal for this purpose. It can be explained as a slightly ellipsoidal expanding shell, where the asym- metry is due to a slight anisotropy in the initial expansion velocity. Very few planetary nebulae have the simple structure of the Ring Nebula. In fact, there is a baffling variety in the shapes of these objects. Most of them, however, show symmetry about a plane, which we might identify with the equator of the central star. The expansion seems to take place mainly in the direction of the poles. This could be caused by the presence of a massive ring of material around the equator, which would direct the expansion toward the poles. This ring might have been left over from the giant phase of the star. This agreeable situa- tion came to an abrupt end when Hubble Space Telescope images of planetary nebulae, starting with the Cat’s Eye Nebula (NGC 6543), showed far more com- plex structures than had been previously sus- pected. This complexity, particularly its fine detail, could not be ex- plained by the model of an equatorial ring direct- ing a general expansion toward the poles. Attempts to explain these structures seem to fall into two categories. The presence of a companion star would provide both the dy- namical perturbations and the symmetry plane (in this case the orbital plane) required by the observa- tions.

  • Planetary Nebula
    How Far Away Is It – Planetary Nebula Planetary Nebula {Abstract – In this segment of our “How far away is it” video book, we cover Planetary Nebula. We begin by introducing astrophotography and how it adds to what we can see through a telescope with our eyes. We use NGC 2818 to illustrate how this works. This continues into the modern use of Charge-Coupled Devices and how they work. We use the planetary nebula MyCn18 to illustrate the use of color filters to identify elements in the nebula. We then show a clip illustrating the end-of-life explosion that creates objects like the Helix Planetary Nebula (NGC 7293), and show how it would fill the space between our Sun and our nearest star, Proxima Centauri. Then, we use the Cat’s Eye Nebula (NGC 6543) to illustrate expansion parallax. As a fundamental component for calculating expansion parallax, we also illustrate the Doppler Effect and how we measure it via spectral line red and blue shifts. We continue with a tour of the most beautiful planetary nebula photographed by Hubble. These include: the Dumbbell Nebula, NGC 5189, Ring Nebula, Retina Nebula, Red Rectangle, Ant Nebula, Butterfly Nebula, , Kohoutek 4- 55, Eskimo Nebula, NGC 6751, SuWt 2, Starfish, NGC 5315, NGC 5307, Little Ghost Nebula, NGC 2440, IC 4593, Red Spider, Boomerang, Twin Jet, Calabash, Gomez’s Hamburger and others culminating with a dive into the Necklace Nebula. We conclude by noting that this will be the most likely end for our Sun, but not for billions of years to come, and we update the Cosmic Distance Ladder with the new ‘Expansion Parallax’ rung developed in this segment.} Introduction [Music @00:00 Bizet, Georges: Entracte to Act III from “Carman”; Orchestre National de France / Seiji Ozawa, 1984; from the album “The most relaxing classical album in the world…ever!”] Planetary Nebulae represent some of the most beautiful objects in the Milky Way.

  • 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.

  • Messier Objects
    Messier Objects From the Stocker Astroscience Center at Florida International University Miami Florida The Messier Project Main contributors: • Daniel Puentes • Steven Revesz • Bobby Martinez Charles Messier • Gabriel Salazar • Riya Gandhi • Dr. James Webb – Director, Stocker Astroscience center • All images reduced and combined using MIRA image processing software. (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.

This major work contains an extensive star catalogue, which lists star co-ordinates and magnitude estimates, as well as detailed star charts. Other topics include descriptions of nebulae and Arabic folk astronomy. As I mentioned before, al-Ṣūfī’s work was first translated into Persian by al-Ṭūsī. It was also translated into Spanish in the 13th century during the reign of King Alfonso X. The introductory chapter of al-Ṣūfī’s work was first translated into French by J.J.A. Caussin de Parceval in 1831. However in 1874 it was entirely translated into French again by Hans Karl Frederik Schjellerup, whose work became the main reference used by most modern astronomical historians. In 1956 al-Ṣūfī’s Book of the fixed stars was printed in its original Arabic language in Hyderabad (India) by Dārat al-Ma‘aref al-‘Uthmānīa.

The project was carried out in partnership with The Navajo Nation Council, Office of the Speaker. The project evolved from a 2004 NASA Explorer Institute Focus Group conducted by ArtReach International. In the Focus Group, members of the Navajo education community identified needs and desires in partnering with NASA on educational initiatives. The educational materials created within the NASA and the Navajo Nation project, this activity booklet and a short film, both entitled “S-’ Baa Hane’ - Story of the Stars,” are a direct result of the Focus Group’s findings.
