It’s all… — 8 Comments

  1. We don’t get to look in the sky and see any blue planets. That alone makes it interesting. It reminds me of the Christmas message from the moon (or thereabouts) of Apollo 8.

  2. A grain of sand in the Sahara. No wonder the aliens haven’t found us

  3. As the linked article points out, the Messenger spacecraft orbiting Mercury imaged Earth on the same day, and you can also see the Moon in that photo.

    APOD has them both.

  4. Umm…it’s not perspective, folks, it’s DISTANCE!

    NTL, Saturn is HUGE compared to our little rock. If Saturn was the size of a basketball (10″ diameter), Earth would be about the size of a pingpong ball (0.9″ dia).
