1817 — Henry David Thoreau was born in Concord, Massachusetts. The writer, philosopher and naturalist became known for Walden, his ideas about simple living and his close observations of the natural world. His work may feel especially relatable to anyone who has found a little peace beside the Mississippi or along a Hastings trail. Library of Congress
2022 — NASA released the James Webb Space Telescope’s first full collection of images and spectra. The remarkable views demonstrated Webb’s ability to study everything from nearby planets to some of the earliest galaxies. It was the beginning of a new era of space science—and a reminder that a Sunday sky can hold quite a bit more than sunshine. NASA Science
