A Basic Requirement for Studying the Heavens Is Determining Where In
Abasic requirement for studying the heavens is determining where in the sky things are. To specify sky positions, astronomers have developed several coordinate systems. Each uses a coordinate grid projected on to the celestial sphere, in analogy to the geographic coordinate system used on the surface of the Earth. The coordinate systems differ only in their choice of the fundamental plane, which divides the sky into two equal hemispheres along a great circle (the fundamental plane of the geographic system is the Earth's equator) . Each coordinate system is named for its choice of fundamental plane. The equatorial coordinate system is probably the most widely used celestial coordinate system. It is also the one most closely related to the geographic coordinate system, because they use the same fun damental plane and the same poles. The projection of the Earth's equator onto the celestial sphere is called the celestial equator. Similarly, projecting the geographic poles on to the celest ial sphere defines the north and south celestial poles. However, there is an important difference between the equatorial and geographic coordinate systems: the geographic system is fixed to the Earth; it rotates as the Earth does . The equatorial system is fixed to the stars, so it appears to rotate across the sky with the stars, but of course it's really the Earth rotating under the fixed sky. The latitudinal (latitude-like) angle of the equatorial system is called declination (Dec for short) . It measures the angle of an object above or below the celestial equator. The longitud inal angle is called the right ascension (RA for short). -

The Distribution of Molecular Hydrogen in Planetary Nebulae
THE DISTRIBUTION OF MOLECULAR HYDROGEN IN PLANETARY NEBULAE J. W. V. Storey, B. L. Webster and P. Payne School of Physics, University of New South Wales Kensington, Australia M. A. Dopita Mt. Stromlo & Siding Spring Observatory Canberra, Australia ABSTRACT. A correlation has been found between strong molecular hydro- gen emission and the morphological type of a planetary nebula. Those with an equatorial toroid and bipolar extensions have H^ 1-0 S(l) stronger than Brackett Ύ. H? maps of several objects, and NGC 2346 in particular, are consistent with a fast stellar wind interacting with an anisotropic medium. The first detection of infrared lines of molecular hydrogen from a planetary nebula was made in 1975 in NGC 7027. Since that time, some 35 planetaries have been searched for in H? at various detection levels, and most planetaries have revealed a detectable emission of H^. The ra- tio of this emission to ionized gas content may vary over many orders of magnitude. We propose that planetary nebulae with very strong H~ emission be- long to one morphological class. These are characterised By a dominant equatorial toroid, and bipolar extensions. Planetaries of this form pre- dominantly fall into a class called Type I. Type I planetaries are dis- tinguished by their bipolar structure as well as a high Ν and He abun- dances, and some, but not all, have a pronounced equatorial toroid plus less dense extended polar lobes. To test our hypothesis we chose a se- ries of Type I planetaries to be observed in H^ on the Anglo-Australian Telescope. -

The list was compiled Featured content by Sir Patrick Caldwell-Moore, better known as Patrick Moore, as a complement to the Messier Catalogue. Current events The Messier Catalogue is used frequently by amateur astronomers as a list of interesting deep-sky objects for observations, but Moore noted that the list did not include Random article many of the sky's brightest deep-sky objects, including the Hyades, the Double Cluster (NGC 869 and NGC 884), and NGC 253. Moreover, Moore observed that the Donate to Wikipedia Messier Catalogue, which was compiled based on observations in the Northern Hemisphere, excluded bright deep-sky objects visible in the Southern Hemisphere such [1][2] Interaction as Omega Centauri, Centaurus A, the Jewel Box, and 47 Tucanae. He quickly compiled a list of 109 objects (to match the number of objects in the Messier [3] Help Catalogue) and published it in Sky & Telescope in December 1995. About Wikipedia Since its publication, the catalogue has grown in popularity and usage within the amateur astronomical community. Small compilation errors in the original 1995 version Community portal of the list have since been corrected. Unusually, Moore used one of his surnames to name the list, and the catalogue adopts "C" numbers to rename objects with more Recent changes common designations.[4] Contact Wikipedia As stated above, the list was compiled from objects already identified by professional astronomers and commonly observed by amateur astronomers. -
Annual Report Astronomy Australia Limited
2011 / 12 Annual Report Astronomy Australia Limited Vision Astronomers in Australia will have access to the best astronomical research infrastructure. Mission AAL will achieve its vision by: 1. Engaging with Australian astronomers to advance the national research infrastructure priorities of the Australian astronomy decadal plan. 2. Advising the Australian Government on future investments in national astronomical research infrastructure. 3. Managing investments in national astronomical research infrastructure as required. Principles 1. Access to major astronomical research infrastructure should be available to any Australian-based astronomer purely on scientific merit. 2. The concept of national astronomical research infrastructure includes Australian participation in international facilities. 3. The AAO and CSIRO are empowered by the Australian Government to provide a component of the national astronomical research infrastructure and there is no need for AAL to directly manage investments to upgrade or operate the AAT and ATNF. Front cover image Gemini Legacy image of the complex planetary nebula Sh2-71 as imaged by the Gemini Multi-Object Spectrograph on Gemini North on Mauna Kea in Hawai‘i. A research team, led by Australian astronomers David Frew and Quentin Parker (Macquarie University, Sydney) are studying the dimmer, bluer star to understand its nature. The long-assumed central star is the brightest star near the centre, but the much dimmer and bluer star (just to the right and down a little) might be the parent of this beautiful object. The image is composed of three narrow- band images, and each is assigned a colour as follows: H-alpha (orange), HeII (blue) and [OIII] (cyan).

The Caldwell Catalogue+Photos
The Caldwell Catalogue was compiled in 1995 by Sir Patrick Moore. He has said he started it for fun because he had some spare time after finishing writing up his latest observations of Mars. He looked at some nebulae, including the ones Charles Messier had not listed in his catalogue. Messier was only interested in listing those objects which he thought could be confused for the comets, he also only listed objects viewable from where he observed from in the Northern hemisphere. Moore's catalogue extends into the Southern hemisphere. Having completed it in a few hours, he sent it off to the Sky & Telescope magazine thinking it would amuse them. They published it in December 1995. Since then, the list has grown in popularity and use throughout the amateur astronomy community. Obviously Moore couldn't use 'M' as a prefix for the objects, so seeing as his surname is actually Caldwell-Moore he used C, and thus also known as the Caldwell catalogue. http://www.12dstring.me.uk/caldwelllistform.php Caldwell NGC Type Distance Apparent Picture Number Number Magnitude C1 NGC 188 Open Cluster 4.8 kly +8.1 C2 NGC 40 Planetary Nebula 3.5 kly +11.4 C3 NGC 4236 Galaxy 7000 kly +9.7 C4 NGC 7023 Open Cluster 1.4 kly +7.0 C5 NGC 0 Galaxy 13000 kly +9.2 C6 NGC 6543 Planetary Nebula 3 kly +8.1 C7 NGC 2403 Galaxy 14000 kly +8.4 C8 NGC 559 Open Cluster 3.7 kly +9.5 C9 NGC 0 Nebula 2.8 kly +0.0 C10 NGC 663 Open Cluster 7.2 kly +7.1 C11 NGC 7635 Nebula 7.1 kly +11.0 C12 NGC 6946 Galaxy 18000 kly +8.9 C13 NGC 457 Open Cluster 9 kly +6.4 C14 NGC 869 Open Cluster
