Open Star Cluster NGC 6791 - Ancient Stellar Gathering in Lyra #1894514 (License: Personal Use)

This Hubble Space Telescope image captures NGC 6791, a remarkably old open cluster situated about 13,300 light-years away in the constellation Lyra. Its stars are unusually metal-rich for their age, offering astronomers critical insights into galactic chemical evolution and stellar aging. The cluster’s dense core and surrounding field stars highlight the dynamic structure of Milky Way star-forming regions.

Used on astronomy education sites, NASA/ESA press releases, and astrophysics blogs to illustrate stellar populations, cluster evolution, and deep-sky observing targets; matches user intent for learning about star clusters, cosmology, or telescope imaging.
