Globular cluster 47 Tucanae (NGC 104).
Globular cluster 47 Tucanae (NGC 104).

47 Tucanae, also known as NGC 104, is the second brightest globular cluster in the Milky Way galaxy, surpassed only by Omega Centauri. It is located in the southern constellation of Tucana. Globular clusters are massive, ancient collections of stars, typically numbering in the thousands to hundreds of thousands, packed tightly into a spherical shape.1234

47 Tucanae is approximately 14,700 light-years away from Earth and possesses a strong central concentration of stars. For an observer within the cluster, the sky would appear as bright as twilight due to the immense number of nearby stars. These clusters are among the oldest objects in our galaxy, with ages estimated between 11 and 13 billion years.124
