Starwatch: keep an eagle eye out for Aquila in full flight

Constellation's brightest star, Altair, gives out 11 times more light than our sun

The celestial eagle is in full flight at this time of the year for the northern hemisphere.

The constellation of Aquila is one of the 48 constellations defined by Ptolemy in the 2nd century, though it had been mentioned in Greek tradition as long ago as the 4th century BC by Eudoxus. In mythology, Aquila represents the eagle that holds Zeus's thunderbolts.
