Comet NEOWISE streaks across the Northwestern sky above the Ridgefield National Wildlife Refuge in north Clark County on July 19. While it is visible to the naked eye, it appears as a light, white smudge under the right side of the Big Dipper. The comet, discovered in March, approached its closest point to earth on July 23, when it was 64 million miles away (about two-thirds of the distance between Earth and the sun). It's next swing through the inner solar system is expected in 6,800 years. The last time it swung through our solar neighborhood, humans had not begun to write or use numerals. Given the changes in civilization since then, what will our world be like when NEOWISE next visits in about the year 8,000? What a fun thing to speculate about.
