Damn . This , noblewoman and gentlemen , is what stargazers call a globular cluster — a spheric grouping of gravitationally bond celestial bodies , swirling about deep in the ink-black black of space . [ Hi - Re available here ]
There are somewhere between 150 and 158 orbicular clusters in our galaxy ( the exact number depend onwhoyouask ) , but the one you see up top — known to astronomers as “ NGC 6752 ” — is one of the brightest in the entire night sky . It ’s also one of the most ancient ingathering of celestial body we ’ve ever observe ; at over 10 billion years one-time , the luminosity from NGC 6752 were shining more than five billion years before our solar system even exist .
According to NASA :
NGC 6752 contains a high numeral of “ blue straggler ” whizz , some of which are seeable in this image . These stars display characteristic of whiz young than their neighbour , despite simulation suggesting that most of the stars within global clusters should have mould at approximately the same time . Their origin is therefore something of a mystery .
Studies of NGC 6752 may shed spark on this position . It appears that a very high number — up to 38 percent — of the stars within its nub neighborhood are binary systems . hit between star in this tumultuous arena could produce the gamey stragglers that are so prevalent .
