Sky of Two Hemispheres
As seen on Astronomy Picture of the Day why the constellation Orion stands so different in these two images? Move the slider on the image to see the constellation figure. Some of the familiar constellations of the northern hemisphere are also visible from the south but they appear upside down! Both images are taken in December and the field of view is similar. The left image is from the southern-most Australia in the beautiful island of Bruny, off the cost from Tasmania. In this moonlit night the Orion stands on its head above the Southern Ocean (Antarctic Ocean). The right image shows the Hunter above Alborz Mountains of Iran. The comparing images also illustrate two different environment at the same time. The snow-covered landscape displays the beginning of winter in northern hemisphere while in the south the new year eve is during the warm of summer. The northern image is from Dec 2007 and the southern one is from Dec 2003.
