A comet heading inbound from deep in the solar system on account of the European Space Agency’s Rosetta mission left earth in 2004 and 10 years later arrived at its object of study.Early Thursday morning, Comet 67P/Churyumov-Gerasimenko made its closest approach to the sun (also known as its perihelion), whipped around it, and has begun its long journey back out, deeper into the cold.
As we’ve seen this year from spacecraft observing the dwarf planet Ceres, the dwarf planet Pluto, and earth itself,thus,don’t expect to attain the instantaneous photos that inspire awe across languages and national boundaries.What scientists are looking for may be awe-inspiring; it’s just a different kind of awe.
At the cosmic chemistry,Rosetta can be looked at.In the wake of 67P’s approach, the sun’s energy will burn away its ice and dust faster and faster. Scientists expect a kind of heat lag. The comet’s warmest temperature, and peak activity, will come after perihelion—just as the hottest day of summer comes a couple of weeks after the summer solstice.
