NGC 104, also known as 47 Tucanae, is a globular cluster located in the constellation Tucana. It is one of the brightest globular clusters visible from Earth and is approximately 13,000 light-years away. NGC 104 contains hundreds of thousands of stars, tightly packed together, and is estimated to be around 13 billion years old. This cluster is notable for its rich population of stars, including many red giants and blue stragglers. NGC 104 is often studied by astronomers to understand stellar evolution and the dynamics of star clusters. Its brightness and proximity make it a popular target for both amateur and professional astronomers.
