Hubble Telescope, Captures Image of Saturn's , Mysterious Spokes.<br />Fox News reports that NASA's <br />Hubble Space Telescope has captured <br />a remarkable new image of Saturn. .<br />According to the space agency, the images mark <br />the beginning of the ringed planet's "spoke season," <br />which comes as it reaches its equinox.<br />The cause of the enigmatic spokes <br />has yet to be fully explained.<br />Fox News reports that Saturn's <br />tilted axis means it has <br />seasons just like Earth.<br />However, its much larger orbit means <br />that each of Saturn's four seasons <br />last for around seven Earth years.<br />The spokes were first observed <br />by NASA's Voyager mission <br />in the early 1980s. .<br />Scientists believe that the spokes are <br />caused by the planet's magnetic field, <br />however, this has yet to be proven.<br />Despite years of excellent observations <br />by the Cassini mission, the precise beginning <br />and duration of the spoke season is still <br />unpredictable, rather like predicting <br />the first storm during hurricane season, Amy Simon, NASA senior planetary scientist head of the Hubble <br />Outer Planet Atmospheres Legacy (OPAL) program, via Fox News.<br />Fox News reports that the last time Saturn <br />experienced an equinox was in 2009, when the <br />Cassini spacecraft was orbiting the massive gas giant.<br />It's a fascinating magic trick <br />of nature we only see on Saturn<br /> – for now at least, Amy Simon, NASA senior planetary scientist head of the Hubble <br />Outer Planet Atmospheres Legacy (OPAL) program, via Fox News
