Primordial Dry Ice Fuels Comet JetsCollege Park MD (SPX) Nov 11, 2010 One of the biggest comet findings coming out of the amazing images and data taken by the University of Maryland-led EPOXI mission as it zipped past Comet Hartley 2 last week is that dry ice is the 'jet' fuel for this comet and perhaps many others. Images from the flyby show spectacular jets of gas and particles bursting from many distinct spots on the surface of the comet. This is the first time images of a comet have been sharp enough to allow scientists to link jets of dust and gas with specific ... read more |
