We've seen lots of pictures of our planet, and you've got to admit, we have a beautiful blue marble. But what does Earth look like from hundred million miles away?

The image above was captured by Solar Terrestrial Relations Observatory B (STEREO-B) showing comet PanSTARRS and Earth last month.

PanSTARRS was about .3 astronomical units from the Sun and about 1.1 AU from Earth (AU is roughly 93 million miles, the distance from Earth to the Sun). NASA says:
The HI [Heliospheric Imager] instrument observes the area just off the limb of the Sun (left) in order to detect the faintly visible light of the solar wind and coronal mass ejections (CMEs) as they blow out into the solar system. STEREO-B was on the far side of the Sun from the Earth, at about a 150 to 160 degree angle from the Earth-Sun line. Puffs of solar wind and from a CME are visible in a video made from the same images in March. [NASA via Discover]
