Today's APOD (Astronomy Picture Of the Day, a NASA posting) is quite striking -- the same section of sky, including the constellation Orion, taken from sites in the northern and southern hemispheres -- specifically Tasmania and Iran. Lovely. [Click on image to enlarge for best effect. Note that Orion appears upside-down between photos, visual proof that they are taken from different hemispheres, not unlike a plane appearing to reverse orientation as it passes overhead.]
