02 Southern Cross
Asterism Southern Cross The Southern Cross is located in the constellation Crux, the smallest of the 88 constellations. It is one of the most distinctive. With the four stars Mimosa BeCrux, Ga Crux, A Crux and Delta Crucis, forming the arms of the cross. The Southern Cross was also used as a remarkably accurate timepiece by all the people of the southern hemisphere, referred to as the ‘Southern Celestial Clock’ by the portuguese naturalist Cristoval D’Acosta. It is perpendicular as it passes the meridian, and the exact time can thus be calculated visually from its angle. The german explorer Baron Alexander von Humboldt, sailing across the southern oceans in 1799, wrote: “It is a timepiece, which advances very regularly nearly 4 minutes a day, and no other group of stars affords to the naked eye an observation of time so easily made”. Asterism - An asterism is a distinctive pattern of stars or a distinctive group of stars in the sky. Constellation - A grouping of stars that make an imaginary picture in the sky.

I Nomi Delle Stelle
I nomi delle stelle Se state leggendo questa pagina perché volete acquistare il nome di una stella, visitate IAU Theme Buying Stars and Star Names. Altrimenti, proseguite con il testo sottostante. L'UAI intende delineare una distinzione tra i termini nome e designazione. In questo testo, così come in altre pubblicazioni dell'UAI, il nome si riferisce al termine (solitamente colloquiale) utilizzato per una stella nel linguaggio quotidiano, mentre la designazione è esclusivamente alfanumerica e viene usata quasi esclusivamente nei cataloghi ufficiali e nell'astronomia professionale. Storia dei cataloghi stellari La catalogazione delle stelle ha una lunga storia alle spalle. Sin dalla preistoria, culture e civiltà in tutto il mondo hanno dato dei propri nomi alle stelle più luminose e importanti nel cielo notturno. Attraversando le culture greca, latina e araba, alcuni nomi hanno subito pochi cambiamenti e altri sono in uso ancora oggi. Mentre l'astronomia si sviluppava e si evolveva nel corso dei secoli, sorgeva la necessità di un sistema di catalogazione universale, in base al quale le stelle più luminose (e quindi quelle più studiate) fossero conosciute secondo gli stessi appellativi, indipendentemente dal Paese o dalla cultura da cui provenivano gli astronomi. Per risolvere questo problema, gli astronomi durante il Rinascimento hanno tentato di produrre cataloghi stellari seguendo un insieme di regole. Il primo esempio, ancora oggi popolare, è stato introdotto da Johann Bayer nel suo atlante Uranometria del 1603. Bayer ha catalogato le stelle in ogni costellazione con lettere greche minuscole, seguendo l'ordine approssimativo della loro luminosità apparente, in modo che la stella più luminosa di una costellazione fosse solitamente (ma non sempre) etichettata come Alpha, la seconda più brillante fosse Beta, e così via. -

ALL RIGHTS RESERVED. Venture out under a clear night sky, in city or country, bright moon or dark moon, and you will see at least a few stars. Fortunately, the brightest stars visible offer a wide variety of characteristics that can be observed or computed easily. With this activity, students have the chance to see these bright stars and learn that these neighbor stars plotted on the appropriate map echo the construction of the whole Milky Way galaxy. Students will first familiarize themselves with the brighter stars in the evening sky. At first glance, the stars’ positions will appear random. Moving into the classroom, students will plot the positions of the stars in two different coordinate systems. A plot prepared using the stars’ positions in the “equatorial” coordinate system (essentially an expansion of latitude and longitude into the sky) will initially seem to present the apparent randomness of the stars’ positions. -
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). -

Yes, Aboriginal Australians Can and Did Discover the Variability of Betelgeuse
Journal of Astronomical History and Heritage, 21(1), 7‒12 (2018). YES, ABORIGINAL AUSTRALIANS CAN AND DID DISCOVER THE VARIABILITY OF BETELGEUSE Bradley E. Schaefer Department of Physics and Astronomy, Louisiana State University, Baton Rouge, Louisiana, 70803, USA Email: [email protected] Abstract: Recently, a widely publicized claim has been made that the Aboriginal Australians discovered the variability of the red star Betelgeuse in the modern Orion, plus the variability of two other prominent red stars: Aldebaran and Antares. This result has excited the usual healthy skepticism, with questions about whether any untrained peoples can discover the variability and whether such a discovery is likely to be placed into lore and transmitted for long periods of time. Here, I am offering an independent evaluation, based on broad experience with naked-eye sky viewing and astro-history. I find that it is easy for inexperienced observers to detect the variability of Betelgeuse over its range in brightness from V = 0.0 to V = 1.3, for example in noticing from season-to-season that the star varies from significantly brighter than Procyon to being greatly fainter than Procyon. Further, indigenous peoples in the Southern Hemisphere inevitably kept watch on the prominent red star, so it is inevitable that the variability of Betelgeuse was discovered many times over during the last 65 millennia. The processes of placing this discovery into a cultural context (in this case, put into morality stories) and the faithful transmission for many millennia is confidently known for the Aboriginal Australians in particular. So this shows that the whole claim for a changing Betelgeuse in the Aboriginal Australian lore is both plausible and likely. -
Life Histories Stars
Life Cycles Of The Stars This activity helps students conceptualize the time scales involved in astronomical processes – such as the life cycles of the stars. Materials Needed • Star histories (see attached sheets) • Pens, pencils, crayons, stickers, marking pens (to decorate the timelines) • Rulers and/or meter sticks • Register tape, in rolls What To Do: 1. Have students work together in groups of 3 - 5. Give each group one of the six star histories attached. Each of these is a history of a real star in the sky. All are main sequence stars – that is, stars that are currently fusing hydrogen in their cores and have not yet depleted their reserves of fusible hydrogen. 2. Each group will construct a time line showing the life cycle of their star. For each group, there are at least 5 key events that groups need to include in their time lines: (1) Conception (t=0) – when gases that will one day form the star start to gravitationally collapse within a giant cloud of gas (called a nebula). (2) Birth – when hydrogen fusion begins within the core and the new star ignites. (3) Old Age – when © 2002 Exploratorium, www.exploratorium.edu The Exploratorium grants reprint permission of this material for noncommercial, educational use only. Copyright notice must be included on all reprints. Requests for electronic or other uses should be directed to <[email protected]> the hydrogen within the core is exhausted. (4) Death – when the star “dies, usually through the expulsion of the outer layers of gas or with a huge explosion. (5) The Corpse – what remains in space shortly after the star “dies”.
