Orion, Horsehead Nebulae and Orion's Belt
A panoramic view Including the very familiar three bright stars of Orion's belt Alnitak (to the left of the image), Alnilam and Mintaka. Part of the Orion Molecular Cloud and two of the most recognizable sky objects in the constellation Orion, these immense stellar nurseries are approximately 1500 light years distant "The Great Orion Nebula and The Horsehead Nebula".
