                         Astronomy Picture of the Day

    Discover the cosmos! [1] Each day a different image or photograph of our
 fascinating universe is featured, along with a brief explanation written by a
                           professional astronomer.

Explanation: Light-years across, this suggestive [5]  shape known as the
Seahorse Nebula appears in silhouette against a rich, luminous background of
stars. Seen toward the royal northern constellation of Cepheus, the dusty,
obscuring clouds are part of a Milky Way molecular cloud some 1,200
light-years distant. It is also listed as Barnard 150 (B150), one of 182 dark
markings of the sky [6] cataloged in the early 20th century by astronomer E.
E. Barnard [7] . Packs of low mass stars are forming within [8] from
collapsing cores only visible at long infrared wavelengths [9] . Still,
colorful stars in Cepheus add to the pretty, galactic skyscape [10] .
