The name is due to William Parsons, 3rd Earl of Rosse, convention during May 2020. who observed the object in 1840 and produced a drawing that looked somewhat like a crab. The object is about 6,300 light-years distant with a mean radius of 5 light-years. Currently, at magnitude 8.4, it exploded and was visible in the daytime sky of July 1054 A.D.

The completely their hobby with the public. computerized telescopes we have today, the images we can take, the increasing involvement of amateur TCAA OFFICERS & CHAIRPERSONS astronomers with keeping and maintaining databases for President Tim Stone President, Director, & Property Manager use by professionals, and even more frequent pro/am collaborations, would have Tim Stone 309-531-2401 blown our mind 20 years ago. Getting into astronomy has never been simpler or [email protected] more rewarding. Vice President & Director/Membership Coord. It’s impossible for me to imagine what our hobby will be like ten years from Tom Willmitch 309-846-2423 now. I hope I can continue my active participation for these coming years, and I [email protected] certainly believe TCAA will be alive and well at the close of the next decade. It is my Treasurer & Director/Registered Agent fervent hope that everyone reading this will resolve anew to actively engage in Dave Osenga 309-287-0789 astronomy as these years come and go. The opportunity is clear and amazingly [email protected] present. Secretary & Director/Historian/Editor Thanks to the public relations functions of major scientific organizations such Carl J.

Yet they rarely have anyone who 5th Director/Assistant Property Manager can really explain what it all means to them. We can be that voice. Scott Wade 309-310-2464 Here’s an example of what I’m talking about. Everyone seems to be talking [email protected] about Betelgeuse’s current brightness minimum. The media is discussing the Astronomical League Correspondent possibility that Betelgeuse may supernova soon. Yet, if you asked most people to Robert Finnigan 309-846-9533 point out Betelgeuse, they couldn’t possibly do that. We can! We can point our [email protected] telescopes at that star, discuss its variability with them, discuss its color and age Technology Coordinator with them. We know Betelgeuse personally, and there are plenty of people who Justin Meyer 630-649-0611 [email protected] would like to meet it. This is what I’m talking about when I say, “Let’s be the voice of astronomy in Webmaster our community.” Read up on current astronomy events. Read this newsletter.

[email protected] Speaking of our club, our TCAA Holiday Party was quite a success again this year. We had approximately twenty of our members in our home, and we all had a The OBSERVER great time. We talked about astronomy, and about other things. We got to know Carl J. Wenning, Editor better some people we didn’t know so well before.

  • The Astronomical Garden of Venus and Mars-NG915: the Pivotal Role Of
    The astronomical garden of Venus and Mars - NG915 : the pivotal role of Astronomy in dating and deciphering Botticelli’s masterpiece Mariateresa Crosta Istituto Nazionale di Astrofisica (INAF- OATo), Via Osservatorio 20, Pino Torinese -10025, TO, Italy e-mail: [email protected] Abstract This essay demonstrates the key role of Astronomy in the Botticelli Venus and Mars-NG915 painting, to date only very partially understood. Worthwhile coin- cidences among the principles of the Ficinian philosophy, the historical characters involved and the compositional elements of the painting, show how the astronomi- cal knowledge of that time strongly influenced this masterpiece. First, Astronomy provides its precise dating since the artist used the astronomical ephemerides of his time, albeit preserving a mythological meaning, and a clue for Botticelli’s signature. Second, it allows the correlation among Botticelli’s creative intention, the historical facts and the astronomical phenomena such as the heliacal rising of the planet Venus in conjunction with the Aquarius constellation dating back to the earliest represen- tations of Venus in Mesopotamian culture. This work not only bears a significant value for the history of science and art, but, in the current era of three-dimensional mapping of billion stars about to be delivered by Gaia, states the role of astro- nomical heritage in Western culture. Finally, following the same method, a precise astronomical dating for the famous Primavera painting is suggested. Keywords: History of Astronomy, Science and Philosophy, Renaissance Art, Educa- tion. Introduction Since its acquisition by London’s National Gallery on June 1874, the painting Venus and Mars by Botticelli, cataloged as NG915, has remained a mystery to be interpreted [1]1.

    RASC Observing Committee Explore the Universe Observing Certificate Second Edition Explore the Universe Observing Certificate Welcome to the Explore the Universe Observing Certificate Program. This program is designed to provide the observer with a well-rounded introduction to the night sky visible from North America. Using this observing program is an excellent way to gain knowledge and experience in astronomy. Experienced observers find that a planned observing session results in a more satisfying and interesting experience. This program will help introduce you to amateur astronomy and prepare you for other more challenging certificate programs such as the Messier and Finest NGC. The program covers the full range of astronomical objects. Here is a summary: Observing Objective Requirement Available Constellations and Bright Stars 12 24 The Moon 16 32 Solar System 5 10 Deep Sky Objects 12 24 Double Stars 10 20 Total 55 110 In each category a choice of objects is provided so that you can begin the certificate at any time of the year. In order to receive your certificate you need to observe a total of 55 of the 110 objects available. Here is a summary of some of the abbreviations used in this program Instrument V – Visual (unaided eye) B – Binocular T – Telescope V/B - Visual/Binocular B/T - Binocular/Telescope Season Season when the object can be best seen in the evening sky between dusk. and midnight. Objects may also be seen in other seasons. Description Brief description of the target object, its common name and other details.

  • 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).
