Dubbed the Orion Nebula, this particular nebula is among the brightest in our night sky and one of the most widely studied nebula in the history of the science. Situated near Orion’s Belt constellation (where it is visible to the naked eye as the middle star in Orion’s sword), the Orion Nebula is home to thousands of stars, all in various stages of life. It has been speculated that human civilizations as early as the Mayans were aware of the nebula and included it in their myths.
