  2. Flags and Astronomy For many countries the national flag is connected with astronomy:

  3. With the Sun: Bangladesh Japan Argentina Uruguay Flags and Astronomy For many countries the national flag is connected with astronomy:

  4. For many countries the national flag is connected with astronomy: With the Sun: Bangladesh Japan Argentina Uruguay With the Moon: With the Moon: Algeria Maldivas Islands Pakistan Malaisia Flags and Astronomy

  5. For many countries the national flag is connected with astronomy: With the Sun: Bangladesh Japan Argentina Uruguay With the Moon: With the Moon: Algeria Maldivas Islands Pakistan Malaisia With stars United States of America Europa China Syria Flags and Astronomy

  6. With constellation(s) (mainly Southern Cross): Papouasia New Guinea Brazil New Zeland Australia Flags and Astronomy

  7. One country has an astronomic instrument on the national flag: it’s Portugal with an astrolab: With constellation(s) (mainly Southern Cross): Papouasia New Guinea Brazil New Zeland Australia Detail: astrolab Flags and Astronomy This list is not limited! You can find other examples.

  8. Flags and Astronomy 1st step: Sun, Moon and stars Sun : flags are connected to religious reasons: Japan ( Sun Godness Amaterasu is said to be the Emperor’s ancestress) ; Argentina (Inca god Inti ) or for poetic reason : Bengladesh ( Tagore’spoem :Thanksgiving) Moon:most of the countries that have the Moon on their national flag are muslim ones. For many cultures, the Sky is the land of the perfection, the Heaven; the link between the Sky and us is the light of the stars, perfect objects.

  9. Flags and Astronomy About the European Flag An interpretation of this flag: Europa is a christian land The blue color is the color of Virgo and the cercle of the twelve golden stars is the crown of Virgo You can see the Virgo with her crown on a painting inside the church of the benediktin monastery of Ettal (Bavaria, Germany).

  10. Flags and Astronomy 2nd step: Southern Cross Constellation on three flags: New Zeland, Australia , Brazil Southern Cross Constellation has been chosen by countries of Southern Hemisphere because the sky helpt travellers inland or at sea.

  11. Flags and Astronomy What can we see? On the New Zeland flag : South Cross with 4 stars On the Australian flag : South Cross with 5 stars! Why? On the Brazilian flag: South Cross with 5 stars but this South Cross is axial Symetric with the South Cross of the Australian flag! Why? And more than that, they are many stars (27 exactly) on the brazilian flag. What do they stand for?

  12. Flags and Astronomy 3th step : Difference between New Zeland flag and Australian flag The 5th star who appears on the Australian flag and not on the New Zeland flag is εCru This is a picture of the South Cross made with Stellarium (Free software) The five brightest stars are: α Cru (Acrux) Mag: 1.25 β Cru ( Mimosa) Mag: 1.25 γ Cru ( Gacrux) Mag: 1.55 δ Cru Mag: 2.75 ε Cru Mag: 3.55 The bigger is magnitude, less bright the star is. On the NewZeland flag there is only the 4 brightest stars of this constellation

  13. Flags and Astronomy 4 th step: The axial symetry of the Southern Cross between the Australian flag and the Brazilian flag Southern Cross see from the Earth Australian flag Brazilian flag Southern Cross seen from the Cosmos It’s the different point of view that explain this axial symetry! Brazilian flag maps the Constellation seen from the Cosmos

  14. Flags and Astronomy 5 th step: the Brazilian flag, a planetarium viewed from the sky The brazilian flag: We can see Southern Cross ( Axial symetry) and other constellations

  15. Flags and Astronomy Sky on Rio De Janeiro the 15th of november 1889 à 12h 30 GMT, the day of independance. Let us use Stellarium

  16. Flags and Astronomy And the same sky seen from the cosmos: we get the brazilian flag!

  17. Flags and Astronomy At the moment of the independance’s declaration the main axe of Southern Cross was perfectly in line with the meridian of Rio de Janeiro On the Brazilian flag , there are 8 constellations: Canis Minor Canis Major Hydra Carina Octans Virgo Australe triangulum and Scorpius Try it: find these constellations an the Brazilian Flag! Nota: there are 27 stars = the number of states in Brazil
