Central in the southern sky is the constellation Orion the Hunter. look for the neat line of three similar-looking stars spaced about equally apart This means that inhabitants of far northern latitudes cannot see constellations that are close to the celestial south pole, because these are always below the horizon for such viewers, spinning once a day around a point that never comes into view. Kevin Beck holds a bachelor's degree in physics with minors in math and chemistry from the University of Vermont.

Whereas points on Earth are described in terms of latitude and longitude, astronomy has units of right ascension and declination. Just draw a line through Orion’s Belt and extend that line toward the horizon. More about Kevin and links to his professional work can be found at www.kemibe.com. This is easiest to find in the winter. The Big Dipper is an asterism, not a true constellation, but just a very clear dipper-shaped pattern of stars. Two of the most recognizable star patterns in the night sky are the belt of Orion and the Big Dipper. Orion’s belt consists of three stars in the middle of the Orion constellation that are so close together they look as if they could be the hunter’s belt.
