Astronomers at the American Astronomical Society meeting in
Nashville presented on May 27 a new atlas of diffuse
interstellar bands, or DIBs, spectroscopic signatures from
gas residing between stars. Scientists have used vertical
rules to highlight the DIBs in the bottom copy of the
spectroscopic data shown above. DIBs are detectable nearly
everywhere astronomers have looked in the Milky Way Galaxy
and even in the nearby Large Magellanic Cloud satellite
galaxy, but have not been observed in the solar system so
far. The new atlas, assembled from data taken at the Apache
Point Observatory by astronomers at several institutions,
should provide a rich source of potential information on
the chemistry and structure of materials between the
stars. PHOTO CREDIT: P. Sonnentrucker (Johns Hopkins), D. G. York (Univ. Chicago), J. Thorburn (Yerkes Obs.), T. Oka, S. Chapman (Univ. Chicago), S. D. Friedman (STScI), B. McCall (Univ.
