Astronomers have discovered a rare and unusual star cluster, NGC 6505, located 590 million light-years away. This star cluster is unique because it is both faint and dense, making it difficult to detect. The discovery was published in the journal Astronomy & Astrophysics.
The star cluster is located in the constellation Sagittarius and is about 4.42 million light-years across. It is so dense that it is difficult to see individual stars within it. The cluster is also very faint, making it difficult to detect with traditional telescopes.
The discovery of NGC 6505 is significant because it provides new insights into the formation and evolution of star clusters. The cluster's unusual properties suggest that it may have formed in a different way than other star clusters. The cluster's discovery also highlights the importance of using new and innovative techniques to explore the universe.
