One of the northern night sky’s superb globular star cluster wonders is our next target: M92 in Hercules. Visible through binoculars as a diffuse star, M92 is a tantalizing sight through telescopes of all sizes.

M92 “suffers” only in that its core is more compact than M13’s, so higher powers and greater patience are required to fully appreciate its glory.īoth of their brightest stars shine within range of small telescopes (12th magnitude) and can be fully resolved if one can reach to 15th magnitude. noted, if M92 were in any other constellation, it would be considered a showpiece. Modern studies have shown M92 is a stunning inner halo globular cluster system 27,000 light-years distant - a tad closer than M13 but about 20 light-years smaller.Įven Messier resolved no stars in it, noting that the core, however, was “clear and bright” and “resembles the nucleus of a large comet.” William Herschel first recognized it as a cluster, while his son John saw this “globular cluster” resolve into “small stars.” Johann Elert Bode discovered the cluster in 1777, saying it was “more or less round, with a pale glow,” which hardly does it justice by modern standards. Like M13, it can be glimpsed with unaided eyes under a dark sky, just 5° southwest of Iota (ι) Herculis, though it is a more significant feat to see it.
