NASA's Deep Impact probe took this image of comet Hartley 2 on Nov. 2, 2010, from a distance of 2.3 million kilometers (1.4 million miles). The white blob and the halo around it are the comet's outer cloud of gas and dust, called a coma. At this distance, the spacecraft captures images with a resolution of about 23 kilometers/pixel (14 miles/pixel).
