Barnard's Milky Way
A 1927 atlas and catalog by famed observer Edward Barnard helped astronomers discover that dark patches in the Milky Way are interstellar dust, not "holes in the sky." MICHAEL E. BAKICH

Extreme imaging
Braving the elements and high altitude, a pair of amateur astrophotographers journeyed to the summit of Mauna Kea in pursuit of dark skies and returned with spectacular images. LISA JOHNSTON WITH JOHN SEFICK
