"Please Pardon Our Dust" with Doug Finkbeiner
Ζωντανή μετάδοση στις 15 Σεπ 2016
Many
beautiful astronomical images result from starlight being absorbed or
scattered by interstellar dust. These processes make for pretty
pictures, but also confound astronomers as they try to see through the
dust. New efforts are creating a 3-D map of cosmic dust within our
galaxy by measuring the colors of nearly 1 billion stars. The resulting
data visualizations are not only picturesque, but also crucial to the
star-mapping mission of the Gaia satellite and the science of the
upcoming Large Synoptic Survey Telescope. Generating this dust map
required years of work - but it beats wiping off shelves and
knick-knacks!
