\nDaphnis, one of Saturn\u2019s small ring-embedded moons, is seen here kicking up waves as it orbits within a gap between rows of icy ring particles.\n<\/p>\n
\nThe image was taken by the international Cassini mission, which recently concluded its incredible 13-year odyssey<\/a> in the Saturn system.\n<\/p>\n \nImages like the one featured here, which was first released in February 2017<\/a>, provide scientists with a close-up view of the complicated interactions between a moon and the planet\u2019s rings, as well as the interactions between the ring particles themselves.\n<\/p>\n \nDaphnis is just 8 km across, but its gravity is powerful enough to disrupt the tiny particles of the A-ring that mark the edge of a gap in the rings called the Keeler Gap. As the moon moves through the Keeler Gap, wave-like features are created in both the horizontal and vertical planes. \n<\/p>\n \nThree wave crests of diminishing size can be seen here in the wake of the moon\u2019s passage. In each subsequent crest, the shape of the wave evolves as the ring particles within the crests collide with one another.\n<\/p>\n \nZooming in towards the tiny moon reveals a faint, thin strand of ring material that almost appears to have been directly ripped out of the A-ring by Daphnis.\n<\/p>\n \nThe images of this feature were taken in visible light, using Cassini\u2019s narrow-angle camera at a distance of about 28 000 km from Daphnis. Image scale is 168 m\/pixel.\n<\/p>\n \nThe Cassini\u2013Huygens mission is a cooperative project of NASA, ESA and ASI, the Italian space agency.<\/p>\n","protected":false},"excerpt":{"rendered":" \nDaphnis, one of Saturn’s small ring-embedded moons, is seen here kicking up waves as it orbits within a gap between rows of icy ring particles.\n<\/p>\n \nThe image was taken by the international Cassini mission, which recently concluded its incredible 13-year odyssey<\/a> in the Saturn system.\n<\/p>\n<\/p>\n
