This weekend, skywatchers can witness a rare blue micromoon, which is the second full moon in May and the smallest full moon of the year. This spectacle, not to be repeated until late 2028, will be particularly striking when viewed alongside Antares, a prominent star in the constellation Scorpius. Astronomers note that in the Southern Hemisphere, the micromoon will temporarily obscure Antares, creating an exciting visual event. The blue micromoon will be approximately 252,360 miles away from Earth, making it 6% smaller and 10% dimmer than an average full moon. Despite its name, the blue micromoon won't actually appear blue; the term refers to the occurrence of two full moons within a single month. For those unable to see it in person, the Virtual Telescope Project will provide live streaming of the event.
