Starry Night is an excellent
aid for exploring the heavens...a superb, well documented program that
will transform you into an expert in no time. "There are few experiences as invigorating as being out in the countryside standing under a canopy of star on a still night. Starry Night conveys that feeling better than any other desktop planetarium" --New York Times |
StarGazer Using The Big Dipper To Find Two Wonderful Stars The handle of the Big Dipper points to Arcturs and then Spica, two of the brightest stars in the spring sky. This view was taken just after sunset on April 10 looking east. Notice that Spica is shaded blue, indicating that it is a young, hot star. Spica and Arcturus are two of the four bright stars in the asterism known as the "Diamond of Virgo". This shows how the stars appear at the present time. This view is taken from the year 9000 AD. Note how far Arcturus has moved from its original location. Because the other three stars in the diamond are more distant and not moving as fast, they have hardly shifted in position at all over the past 7000 years. |
