NASA/Ben Smegelsky Clouds curling around the full “blue” moon gives the night sky an eerie feel in this image from Aug. 19, 2024. As seen here, a blue moon is not actually blue; the third full moon in a season with four full Moons is called a “blue” moon.
Another moon will be visible in the sky the morning of Oct. 25: Jupiter’s icy moon Europa, the destination of NASA’s recently launched Europa Clipper, will be easily observable with binoculars on one side of Jupiter by itself.
