NASA has done it again. Their New Horizons spacecraft captured an amazing phenomenon—a 321-kilometer-high plume spewing from a volcano on Jupiter’s third largest moon, lo. The impressive eruption occurred back in 2007 and was caused by the tug of gravity on the little moon from the planet and its fellow neighboring moons. According to NASA, the constant tugging causes lo to stretch, leading to a buildup of intense friction and heat within its core that blows sky-high every now and then.
