Ua hoʻokuʻu ka US National Aeronautics and Space Administration (NASA) i kahi kiʻi kupanaha o Messier 2, he pūʻulu hōkū honua i ka hui hōkū ʻo Aquarius.
Loaʻa i nā pūʻulu pōʻai he nui nā hōkū. Hoʻopaʻa paʻa ʻia ia mau hale e ka ʻumekaumaha a ʻorbit i ke kikowaena galactic ma ke ʻano he satellite.
ʻAʻole like me nā pūʻulu hōkū hāmama, aia i loko o ka galactic disk, aia nā pūʻulu honua i ka halo. He ʻano spherical symmetrical kēlā mau hale, ʻike maopopo ʻia i ke kiʻi i hōʻike ʻia.
Pono e hoʻomaopopo ʻia ʻo Messier 2, e like me nā puʻupuʻu globular ʻē aʻe, ua ʻike ʻia e ka piʻi ʻana o ka neʻe ʻana o nā hōkū ma ka ʻāpana waena.
Ua manaʻo ʻia aia ʻo Messier 2 ma kahi o 150 mau kukui. Aia ma kahi o 000 mau makahiki māmā ka lōʻihi o ka puʻupuʻu a he 55 mau makahiki māmā ka lōʻihi.
Hoʻohui mākou ua manaʻo ʻia ʻo Messier 2 kekahi o nā puʻupuʻu saturated a compact globular clusters.
Ua hoʻoili ʻia ke kiʻi i paʻi ʻia mai ka Hubble orbital telescope (NASA/ESA Hubble Space Telescope). E hoʻomanaʻo mākou i ka hoʻomaka ʻana o ka Discovery shuttle STS-31 me ka mea i kapa ʻia i lawe ʻia ma ʻApelila 24, 1990, ʻo ia hoʻi, kokoke i 30 mau makahiki i hala. Hoʻolālā ʻia ʻo Hubble e hana a hiki i ka makahiki 2025.
