Rosetta finds comet plume powered from below



Paris (ESA) Oct 27, 2017
Last year, a fountain of dust was spotted streaming from Rosetta's comet, prompting the question: how was it powered? Scientists now suggest the outburst was driven from inside the comet, perhaps released from ancient gas vents or pockets of hidden ice. The plume was seen by ESA's Rosetta spacecraft on 3 July 2016, just a few months before the end of the mission and as Comet 67P/Churyumov-Gerasimenko was heading away from the Sun at a distance of almost 500 million km. "We saw a bright plume ... read more

At the ends of the Solar System, beyond the orbit of Neptune, there is a belt of objects composed of ice and rocks, among which four dwarf planets stand out: Pluto, Eris, Makemake and Haumea. The latter is the least well known of the four and was recently the object of an international observation campaign which was able to establish its main physical characteristics.
