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. -

AN ANALYSIS of FLAG CHANGES in LATIN AMERICA Ralph Kelly
Comunicaciones del Congreso Internacional de Vexilología XXI Vexilobaires 2005 CAUDILLOS, COUPS, CONSTITUTIONS AND CHANGES: AN ANALYSIS OF FLAG CHANGES IN LATIN AMERICA Ralph Kelly Abstract: The paper provides a review of historical changes in the design of national flags in Latin America since independence. Despite the perception that their national flags do not change, a number of Latin American countries have changed the design of their national flag since independence, either in minor ways or by adopting a completely new design. Some countries have experienced frequent flag changes in the past and only two Latin American national flags have never changed since independence. The paper undertakes a statistical analysis of the pattern of such changes and their reasons, which can be categorised into eight factors. The paper seeks to explain the past changes of the national flags of Latin America in the context of the unique history of the continent. Many flag changes in the past have been associated with changes of government, but in the past century the national flag is a more significant symbol than contemporary governments. The paper assumes an existing general knowledge of the designs and meaning of Latin American flags. Illustrations include reproductions from some of the major historical flag books of the Nineteenth Century and new re-constructions by the author. Text: The initial impression of Latin American flags is that they do not change. All of the national flags shown in "The Flags of the Americas" issue of The National Geographic -
