NGC 104, also known as 47 Tucanae, is a massive globular cluster located in the constellation Tucana, about 13,000 light-years from Earth. It’s one of the brightest and most massive globular clusters in the Milky Way, containing several million stars densely packed within a roughly spherical shape. With a diameter of around 120 light-years, NGC 104 is easily visible to the naked eye in the southern hemisphere. The cluster is rich in older stars, giving it a golden hue, and is known for its dense core, where stars are packed thousands of times closer together than in our solar neighborhood.
