On the highest hill of Antananarivo, the capital of Madagascar, known as Tana, you can find one of the few palaces outside Europe. This is the royal palace complex that has been used as the home of the kings of this country since the 17th century. Now it is known as the Queen’s Palace and is one of Tana's cultural sites. Look out at the sky above the palace; can you recognize the constellation above it? Your answer is probably that it looks like the constellation Orion, but it seems that there is something wrong with that? You guessed right, the constellation is Orion, but upside down! The reason is very simple. The night sky view changes with the change of latitude, and the inhabitants of the southern hemisphere and the northern hemisphere observe different views of the night sky.
You may ask, why the Orion Nebula is so distinguished in the heart of the capital? The reason is hidden in the relationship between the transparency of the sky and the diffusion of light. In fact, the clearer the sky, the less light scattered by light pollution, resulting is relatively dark night sky.
