CAPE CANAVERAL, Fla. (AP) — Get set for a rare blue micromoon this weekend — a blue moon that’s also the most distant and smallest-looking full moon of the year. A bonus: The brilliant star Antares will photobomb Sunday’s spectacle for a celestial three-for-one. A blue moon occurs every two to three years when a second full moon squeezes into a single month.
