C93 소개
설명
NGC 6752 is the third-brightest globular cluster in the sky (after Omega Centauri and 47 Tucanae), located about 13,000 light-years away in Pavo. At magnitude 5.4, it is visible to the naked eye and spans 20 arcminutes.
관측 팁
A superb globular visible to the naked eye from dark sites. Binoculars show a bright, granular ball. Any telescope resolves the outer regions into streams of individual stars. A 6-inch scope provides a stunning view at 80-120x. Best from southern locations in summer and autumn.
역사
Discovered by James Dunlop on June 30, 1826 from Australia. It is one of the nearest globular clusters and has been the subject of intensive study, including Hubble observations of its white dwarf population.
재미있는 사실
NGC 6752 has undergone core collapse, resulting in an extremely dense center. Millisecond pulsars discovered in its core are among the fastest-spinning objects known. The cluster also contains one of the first known planetary systems in a globular cluster — a pulsar with a planet-mass companion.
