The cluster contains several young, massive stars and is known for its bright and colorful appearance. Discovered by John Herschel in 1830, NGC 6611 is often studied by astronomers to understand star formation and the evolution of stellar clusters. The cluster is surrounded by gas and dust, which contribute to the formation of new stars, making it a significant area of interest in astrophysics.
