The Largest Working Observatory In The United States

Key Points:

• The W.M. Keck Observatory, located atop Maunakea in Hawai'i at 13,600 feet elevation, hosts two of the world's largest telescopes, benefiting from exceptionally clear, stable, and dark skies ideal for astronomical observation.
• The twin Keck telescopes, each with a 10-meter segmented mirror controlled to nanometer precision, use advanced adaptive optics systems to produce images with clarity surpassing even the Hubble Space Telescope in some wavelengths.
• Keck has contributed to major discoveries including mapping star movements in the Andromeda Galaxy, identifying a galaxy composed mostly of dark matter, detecting distant quasars, and observing a planet still forming around its young star.
• The observatory employs a suite of specialized instruments such as MOSFIRE, DEIMOS, and the Keck Planet Finder to study stars, galaxies, black holes, and cosmic history, enabling insights into the universe's formation and evolution.
• Visitors can access a gallery to view Keck I and learn about its operations after acclimating at the Maunakea Visitors Information Station, with access to the summit restricted to 4WD vehicles to preserve the site and ensure safety.
