Aquila (abbreviation: Aql, genitive: Aquilae)





The Eagle (of Zeus); a distinctive constellation on the celestial equator that spreads across many rich fields. Due to a lane of obscuring dust known as the Great Rift, the Milky Way splits in two through this constellation and also through Ophiuchus. Aquila has been a fruitful hunting ground for nova-seekers, producing four since 1899, including two of the brightest on record. One of these, in AD 389, became as bright as Venus; the other, in 1918, outshone Altair. See below for details of the constellation's brightest stars and interesting deep sky objects.
