Cometary close-up reveals dogbone cast from Eden

Having traveled approximately 13 million miles in space, EPOXI intercepted the comet Hartley 2 yesterday, providing scientists with a close up look at Eden.

Comets and asteroids contain primitive material from the development of our solar system some 4.5 billion years ago. One key difference between the two is the presence of a coma, the temporary atmospheres formed as the comet sheds its volatile compounds in the presence of our star.
