The Rosetta Space Probe's Pictures Of A Comet Are Insane

The European Space Agency's Rosetta space craft arrived in orbit around a comet on Wednesday after a four billion mile journey through space.

These pictures, released by ESA shortly after the announcement, show just how incredible an opportunity to study the comet Rosetta has opened up. ESA explains:

"Comet 67P/Churyumov–Gerasimenko and Rosetta now lie 405 million kilometres from Earth, about half way between the orbits of Jupiter and Mars, rushing towards the inner Solar System at nearly 55 000 kilometres per hour.

The comet is in an elliptical 6.5-year orbit that takes it from beyond Jupiter at its furthest point, to between the orbits of Mars and Earth at its closest to the Sun. Rosetta will accompany it for over a year as they swing around the Sun and back out towards Jupiter again.

Comets are considered to be primitive building blocks of the Solar System and may have helped to ‘seed’ Earth with water, perhaps even the ingredients for life. But many fundamental questions about these enigmatic objects remain, and through a comprehensive,in situstudy of the comet, Rosetta aims to unlock the secrets within."
