Image of NGC 6791, an ancient and unusually metal-rich open star cluster. Thousands of stars, approximately 8 billion years old, are densely packed, defying typical metallicity expectations for stars of this age. This intriguing cluster presents a cosmic puzzle regarding stellar evolution within galactic centers.
