Astronomy Picture of the Day

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

    [2]The featured image shows a central region of IC 2944, the Running
   Chicken Nebula. Visible are stars and dense clouds that form stars one
       day. Please see the explanation for more detailed information.

   Explanation: In one of the brightest parts of [4]Milky Way lies a
   nebula where some of the [5]oddest things occur. NGC 3372, known as the
   [6]Great Nebula in Carina, is home to massive stars and changing
   nebulas. The [7]Keyhole Nebula (NGC 3324), the bright structure just
   below [8]the image center, houses several of these massive stars. The
   entire [9]Carina Nebula, [10]captured here, spans over 300 [11]light
   years and lies about 7,500 light-years away in the [12]constellation of
   Carina. [13]Eta Carinae, the [14]most energetic star in the nebula, was
   one of the brightest stars in the sky in the 1830s, but [15]then faded
   dramatically. While [16]Eta Carinae itself maybe on the verge of a
   supernova explosion, [17]X-ray images indicate that much of the
   [18]Great Nebula in Carina has been a veritable [19]supernova factory.
