The Milky Way
Most of us are familiar with the Milky Way. We may be lucky enough to live in a dark location and can see the misty band of light that stretches across the sky (see Figure 1.1). Others may live in an urban location and so can only glimpse the Milky way as a faint hazy patch that envelops several constellations. But how many of us make a point of observing the Milky Way as a celestial object in its own right? Very few I imagine, which is a pity as it holds a plethora of wonderful delights, ranging from deeply colored double and multiple star systems to immense glowing clouds of gas and mysterious dark nebulae which literally blacken the sky. It also holds quite a few star clusters that really do look like diamonds sprinkled on black velvet, not to mention the occasional neutron star, black hole and possible extra-solar planetary system! In fact, you could spend an entire career observing the Milky Way.
