The twins Castor and Pollux are the two bright stars on top(left and right stars respectively). Along with Taurus are part of the twelve Zodiac constellations, these are the constellations that are in the line of site of the ecliptic. The ecliptic is the plane of Earths orbit around the sun, from our point of view on Earth it is the apparent path the sun and the planets trace as they wander among the stars. Its like an imaginary road that the Sun and the Planets use to move around. Open cluster M35 can be seen here near the left foot of Pollux. About 2 degrees to the left of Propus the orange star on the bottom right.
