Omega Centauri (ω Cen, NGC 5139, or Caldwell 80) is a globular cluster in the constellation of Centaurus that was first identified as a non-stellar object by Edmond Halley in 1677. Located at a distance of 17,090 light-years (5,240 parsecs), it is the largest known globular cluster in the Milky Way at a diameter of roughly 150 light-years. It is estimated to contain approximately 10 million stars, with a total mass of 4 million solar masses, making it the most massive known globular cluster in the Milky Way.

A Sound Garden is an outdoor public art work in Seattle, Washington, United States. It is one of six such works on the National Oceanic and Atmospheric Administration (NOAA) campus, which lies adjacent to Warren G. Magnuson Park on the northwestern shore of Lake Washington. Designed and built by sculptor Douglas Hollis from 1982 to 1983, the sound sculpture is composed of twelve 21-foot (6.4 m) high steel tower structures, at the top of each of which hangs an organ pipe attached to a weather vane that produces soft-toned sounds when stirred by the wind.
