OBJECT DESCRIPTION AND IMAGE SESSION

This young open cluster of stars is around 5 million years old. Most of its stars are young and hot and shine with an intense blue light. Like many open clusters, NGC 2367 is embedded within an emission nebula, the molecular cloud from which its stars were born. In this case the background emission material is part of the Brand 16 Nebula, and of the super shell region GS234-02. NGC 2367 is around 7000 light years from Earth, in the constellation of Canis Major. NGC 2367 was discovered by German British astronomer Sir William Herschel in 1784 using a 6.2 inches (160 mm) diameter Newtonian telescope.
