Object data of M16

Object type: Open cluster + emission nebula
Size: 35'
Magnitude: 6.0 mag
Constellation: Ser
Distance: 7,000 Ly
Notes: The Eagle Nebula (Messier 16) is a conspicuous region of active star formation, situated in Serpens Cauda. The starforming nebula, a giant cloud of interstellar gas and dust, has already created a considerable cluster of young stars. The cluster is also referred to as NGC 6611, the nebula as IC 4703.

Object data of M17

Object type: Emission nebula
Size: 11'
Magnitude: 6.0 mag
Constellation: Sgr
Distance: 5,000 Ly
Notes: The Swan Nebula (Messier 17), also called the Omega Nebula is a region of star formation and shines by excited emission, caused by the higher energy radiation of young stars. Unlike in many other emission nebulae, however, these stars are not obvious in optical images, but hidden in the nebula.
