Image of Comet ISON taken by the Hubble Space Telescope (HST) on April 10, 2013, when, at 386 million miles, ISON was slightly closer to the Sun than Jupiter. A model analysis of the image reveals the solid, icy nucleus of ISON a jet blasting dust particles off the Sunward-facing side of the comet's nucleus. The dust tail extends more than 57,000 miles, far beyond Hubble's field of view (Image credit: NASA).
