The Chameleon's Dark Nebulae
Explanation: The Chameleon is a small constellation near the south celestial pole . Boasting no bright stars , it blends inconspicuously with the starry southern sky. But, taken in dark skies over Namibia, this image reveals a stunning aspect of the shy constellation -- a field of dusty nebulae and colorful stars. Blue reflection nebulae are scattered through the scene, but most eye-catching is the complex of silvery dust clouds that only faintly reflect starlight, punctuated by dense dark nebulae . The dark nebulae stand out because they block out background stars. This view of the cosmic dust clouds spans about 4 degrees on the sky.
