That is the time for the astronomer to get to work. The sequence is repeated backwards in the morning. As twilight ends, the Big Dipper of Ursa Major is now high overhead for those in the mid-northern hemisphere, the Little Dipper of Ursa Minor pointing up to meet it. If far enough north, above 35 degrees north latitude, you can see Cassiopeia swing beneath the pole opposite the Dipper. To the west of the Dippers and around toward Cassiopeia is an immense area of sky so devoid of bright stars that the ancients invented no constellations within it.
Nobody points out the dim figure at astronomy open houses.
Yet the ghostly Giraffe is not without its highlights, one of which is its luminary, Beta. This great star looks faint only because of its large distance of 1000 light years. The star is far enough away, and close enough to the Milky Way, that it is dimmed some 15 percent by interstellar dust. With a mass around 7 times that of the Sun, Beta Cam is only around 40 million years old. Beta Cam is also a double mystery.
