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: [6]Active galaxy NGC 1275 is the central, dominant member
   of the large and relatively nearby [7]Perseus Cluster of Galaxies.
   Wild-looking at visible wavelengths, the active galaxy is also a
   prodigious source of [8]x-rays and [9]radio emission. NGC 1275 accretes
   matter as entire galaxies fall into it, ultimately feeding a
   supermassive black hole at the galaxy's core. This color composite
   [10]image made from Hubble Space Telescope data recorded during 2006.
   It highlights the resulting [11]galactic debris and [12]filaments of
   glowing gas, some up to 20,000 light-years long. [13]The filaments
   persist in NGC 1275, even though the turmoil of galactic collisions
   should destroy them. What keeps the filaments together?
   [14]Observations indicate that the structures, pushed out from the
   galaxy's center by the black hole's activity, are held together by
   magnetic fields. Also known as [15]Perseus A, NGC 1275 spans over
   100,000 light years and lies about 230 million light years away.
