I think that there is probably nothing as beautiful as a full disc image of Earth, though I would like it if I could find one that didn’t focus on the Americas. Either way, this most recent image was taken on August 24, 2011, by the NASA/NOAA GOES-13 satellite.
In the middle of the image can be seen Hurricane Irene as it sweeps in over the Bahamas at 12 miles per hour. To the right is the far west corner of Africa, and you can just see the Antarctic Peninsula down the bottom, reaching up to try and meet the southern tip of South America.
