Look south eastwards (135°) and search for Cygnus first
The brightest star is deneb which is from dhaneb, the Arabic for "tail" (Tail of the swan) Part of the constellation makes up of theNorthern Cross. (Bolder green in the image.)
Now look for Vega in Lyra to the right of Cygnus (see image above). The final of the three stars is another bright star below Deneb and Vega. It is called Altair. It comes froman abreviation of the arabic phrase 'the flying eagle'
Join the three stars up and you have the Sumer triangle.
In the film Contact, (originally a book by Carl Sagan) the message intercepted by Jodi Foster's character is coming from Vega.
Jodie Foster character in Contact 'I was given something wonderful, something that changed me forever... A vision... of the universe, that tells us, undeniably, how tiny, and insignificant and how... rare, and precious we all are! A vision that tells us that we belong to something that is greater then ourselves, that we are not, that none of us are alone!'
