Rosetta ‘sees’ comet emit more and more vapor




Space probe Rosetta Thursday put the time on which 67P / Churyumov-Gerasimenko came closest to the sun. At three minutes past four Dutch summer time on the night of Wednesday to Thursday, the comet was only 186 million kilometers from the sun.

Rosetta came a year ago on August 6 at the comet. Since then, the two along with space lander Philae traveled 750 million kilometers. Because the comet is now close to the sun and absorbs more and more solar heat, the whole heats up. Because of the heat spraying gas, steam and ice with increasing speed in space, writes the European Space Agency. Because of global warming, the coma, the gas cloud around a comet or “atmosphere”, and the tail getting bigger and more impressive.

perihelion rosetta The intensity is at its highest and continues in the coming weeks. Rosetta made beautiful images of them. The images are shot from about 327 kilometers away, an hour before the so-called perihelion was reached. The perihelion is the point at which an object that goes around the sun in an elliptical orbit is closest to the sun.

Astronomers have calculated that the comet now spits up about 300 kilograms of water vapor, a thousand times more than when Rosetta arrived a year ago when the comet. Presumably there will also be about 1000kg per second dust free, which does not make life safer for Rosetta. Because of all the dust and the like were the astronomers probe the continued removal of the comet.
