With the unaided eye, the best-known nebula that is visible from the northern hemisphere (though it is just south of the celestial equator) is the Orion Nebula, a star-forming gaseous region that appears as a fuzzy blob just below the left side of the belt of Orion (the Hunter). The southern hemisphere, which faces the general direction of the center of the Milky Way, has many other beautiful nebulae to observe. Two well-known emission nebulae in the south are the Carina Nebula and the Lagoon Nebula; the best-known dark nebula in the southern sky is the Coalsack, which is easily visible next to the Southern Cross.
