Astronomy Picture of the Day

Explanation: Here you are. Here is everyone you've ever known. Here is every human who has ever lived. Pictured above is the Earth-Moon system as captured by the Cassini mission orbiting Saturn in the outer Solar System. Earth is the brighter of the two spots near the center, while the Moon is visible to its lower left. The unprocessed image shows several streaks that are not stars but rather cosmic rays that struck the digital camera while it was taking the image. The image was snapped by Cassini on Friday and released on Saturday. At nearly the same time, many humans on Earth were snapping their own pictures of Saturn.
