From the classroom, to the Universe

Crux

 Crux or the Southern Cross is probably the most popular constellation in Australia and is as well a symbol in their flag. In the southern hemisphere, it is used to approximate then location of the south celestial pole by extending it 4 1/2 times to where it points. In one aboriginal culture, it is regarded as a stingray.
