Anxious to see the closest shot of Pluto ever? NASA is set to release high res photos soon, but in the meantime, the space agency has posted a "love note back to Earth" with a low-res Instagram image. That marks the first time the agency has given a social network first dibs on a major image, according to Wired. The image itself was snapped by the New Horizon probe 16 hours before its closest approach, some 476,000 miles away. NASA said it will release higher resolution versions of the image later tonight and discuss them in a briefing at 8AM briefing (EDT) on NASA Television. We'll bring you all the details of that a bit later on, but in the meantime, enjoy the best photo ever taken of our solar system's bastard stepchild planet.
