Via the always engrossing Web Curios, we discover this lovely calendar, almanac called Nights on Earth by Phil Mosby that gives one a preview of what astronomical wonders one might behold in the upcoming evenings, assuming clear skies and minimal light pollution, triangulated for one’s location. It strikes just the right balance of coming-attractions without being overwhelming in terms of information and telemetry, and we especially liked the timetables of the various twilights and offer to suggest an event.
