- Lake Forest Park — Thumbnail History (historylink.org)
Lake Forest Park, located along the northern tip of Lake Washington, is one of King County’s first planned communities. It has an estimated population (in 2021) of 13,358. From its inception in 1909 until today, the community has paid great attention to its natural surroundings. It has created a marriage of residential dwellings and wooded terrain quite unlike many other suburban cities.
- Galaxy (Wikipedia)
A galaxy is a system of stars, stellar remnants, interstellar gas, dust, and dark matter bound together by gravity. The word is derived from the Greek galaxias (γαλαξίας), literally ‘milky’, a reference to the Milky Way galaxy that contains the Solar System. Galaxies, averaging an estimated 100 million stars, range in size from dwarfs with less than a hundred million stars, to the largest galaxies known – supergiants with one hundred trillion stars, each orbiting its galaxy’s center of mass. Most of the mass in a typical galaxy is in the form of dark matter, with only a few percent of that mass visible in the form of stars and nebulae. Supermassive black holes are a common feature at the centres of galaxies.
