M16 (NGC 6611)
M16 (NGC 6611) is an open cluster in the constellation Serpens, discovered by Philippe Loys de Chéseaux
in 1745–46. M16 (NGC 611) formed, some 5.5 million years ago, from
the interstellar cloud of gas and dust that it makes visible today as the Eagle Nebula (IC 4703). This famous
nebula, ionized and illuminated by the hot, young O
stars of M16, is still the scene of active star
formation. The brightest star of M16 is of visual magnitude 8.24.
