Rare Photos: Jupiter's Triple-Moon Conjunction in Pictures

Rare Sight on Jupiter

Efrain Morales Rivera

On Jan. 24, 2015, the shadows of three large moons of Jupiter crossed the face of the giant planet. The celestial shadow dance was captured by NASA's Hubble Space Telescope and amateur astronomers. See photos of the rare event in this gallery. HERE: Astrophotographer Efrain Morales Rivera of Aguadilla, Puerto Rico, sent in a composite photo showing the rare triple shadow transit of Jupiter's moons, Io, Callisto and Europa.
