NGC 7089

NGC 7089, also known as Messier 2, is one of the largest and richest globular clusters in the Milky Way. Located in the constellation Aquarius, M2 contains several hundred thousand stars and has a strikingly round and symmetrical appearance. Its dense core and extended halo make it a showcase object for deep imaging. The cluster is extremely old, with an estimated age of around 13 billion years. It hosts a wide variety of evolved stars, including red giants and variable stars, and shows evidence of multiple stellar populations. M2’s brightness and structure make it one of the finest globular clusters in the autumn sky.
