“Star Hopping”…using familiar patterns to help you find unfamiliar objects in the night sky, is a great method used by most amateur astronomers like me. You don’t need a telescope… a pair of binoculars or your eyes will be just fine. Check the photos for some familiar patterns and some easy “new” targets. 🙂 (All illustrations courtesy earthsky.org).
Star Hopping– An Easy Way to Learn the Night Sky
The “Big Dipper”… perhaps the most familiar pattern of stars in the night sky, and the stars Merak and Dubhe in the pot, which point to Polaris, our North Star… and the first star in the handle of the asterism known as the Little Dipper. This picture shows star hopping from Dubhe to Polaris.
Ursa Major (containing the Big Dipper asterism) also allows us to find the constellation of Cassiopeia. Follow the “pointer stars” in the Big Dipper to find Polaris, and then star hop on to Cassiopeia.
The Great Square of Pegasus, now high in the west on winter evenings. Start from the star on the top left of the square, star hop two stars to the left to the star Mirach, then above Mirach to the star Mu, and then the same distance again above Mu to the Andromeda Galaxy.
The belt in the Orion constellation is also another great sign post… with the three stars pointing down, star hop going in a straight line to the left to the bright star Sirius, then reverse direction upward through Orion’s Belt and hop to the right to the red supergiant Aldebaran in Taurus.
