NEW YORK: When the European Space Agency’s Rosetta spacecraft went out to land on and study the comet 67P/Churyumov-Gerasimenko it was truly a groundbreaking moment. And now we are able to enjoy everything that this spacecraft studies through the stunning images that the spacecraft has sent back to earth.
ESA officials comment, “As the comet continues to move closer to the sun, the warming continues and activity rises, and pressure from the solar wind causes some of the materials to stream out into long tails, one made of gas, the other of dust.”
The statement continues, “The comet’s coma will eventually span tens of thousands of kilometers, while the tails may extend hundreds of thousands of kilometers, and both will be visible through large telescopes on Earth.”
But the fact that we are able to get up close and personal with this comet is not the only reason this mission is special. What we have been able to learn about comets—and our galaxy—cannot be matched.
