Starry Night
In the Perseus arm of the Milky Way
The ‘Double Cluster’
Provides the lustre
For the astro-photographer at play
It is so much younger than other star clusters that astronomers find
Created so long after, it’s more illustrious ‘starry and clustery’ peers
Its estimated age is quoted as being, just over, thirteen million years
NGC869 and NGC884 star clusters, in one focussed view combined
Originally catalogued by the ‘Hipparchus the Greek’ two millennia ago in 130 BCE
Rediscovered through a telescope by Bill Herschel, in the early Nineteenth Century
The 'Double Cluster' has both ‘Blue and Red Giant Stars’ when viewed telescopically
‘Blue-shifted’, travelling towards us at 38Km per second, but no threat to you or me
