Astronomy Picture of the Day

                         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: Similar [5] in size to large, bright spiral galaxies in our
neighborhood, IC 342 [6] is a mere 10 million light-years distant [7]  in the
long-necked, northern constellation Camelopardalis [8] . A sprawling island
universe [9] , IC 342 would otherwise be a prominent galaxy in our night sky,
but it is hidden from clear view and only glimpsed through the veil of stars,
gas and dust clouds along the plane of our own Milky Way galaxy [10] . Even
though IC 342's light is dimmed and reddened by intervening cosmic clouds [11]
, this sharp telescopic image [12]  traces the galaxy's own obscuring dust,
young star clusters, and glowing pink star forming regions along spiral arms
that wind far from the galaxy's core [13] . IC 342 may have undergone a recent
burst of star formation [14]  activity and is close enough to have
gravitationally influenced the evolution of the local group [15] of galaxies
and the Milky Way.
