The ten July constellations contain many well-known groups such as Draco, the dragon, Hercules, the strongman, and Scorpius, the scorpion. These groups are famous for their large number of globular star clusters. Scorpius is home to four Messier star clusters, as well as a bright, giant red star known as Antares. Ophiuchus contains an incredible number of Messier globular clusters, seven in all. Two additional globulars can be found in the constellation of Hercules. A small, lenticular galaxy can be seen lurking in the constellation of Draco and Serpens contains two Messier objects, a galaxy and a nebula. This is a beautiful diffuse nebula known as the Eagle Nebula. Click on any constellation below for more information.
