- The Montlake Cut, between the Montlake and University District neighborhoods in Seattle, connects Lake Washington and Lake Union as part of the Lake Washington Ship Canal. When it was completed in 1916, it marked the realization of a 62-year-old idea to link the lakes with Puget Sound, creating a freshwater harbor in Seattle and a waterway connecting Seattle’s shipping harbor in Elliott Bay with the resource-rich interior of King County. The canal boosted economic development on the lakes and helped reduce flooding in the Duwamish River valley (its former outlet), but it also had far-reaching environmental and cultural consequences.

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.
