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.

   Explanation: [8]This fantastic skyscape lies near the edge [9]of NGC
   2174 a star forming region about 6,400 light-years away in the
   nebula-rich constellation of Orion. It follows mountainous clouds of
   gas and dust carved by winds and radiation from the region's newborn
   stars, now found [10]scattered in open star clusters embedded around
   the center of NGC 2174, off the top of the frame. Though star formation
   continues within these dusty cosmic clouds they will likely be
   dispersed by the energetic newborn stars within a few million years.
   Recorded at infrared wavelengths by the Hubble Space Telescope in 2014,
   the [11]interstellar scene spans about 6 light-years. Scheduled for
   launch in 2021, the [12]James Webb Space Telescope is optimized for
   exploring the Universe at infrared wavelengths.
