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: The Crab Nebula is cataloged as M1, the first object on
   [7]Charles Messier's famous list of things which are not comets. [8]In
   fact, the Crab is now known to be a [9]supernova remnant, expanding
   debris from massive star's death explosion, witnessed on planet Earth
   in 1054 AD. [10]This brave new image offers a 21st century view of the
   Crab Nebula by presenting image data from across the
   [11]electromagnetic spectrum as wavelengths of visible light. From
   space, [12]Chandra (X-ray) [13]XMM-Newton (ultraviolet), [14]Hubble
   (visible), and [15]Spitzer (infrared), data are in purple, blue, green,
   and yellow hues. From the ground, [16]Very Large Array radio wavelength
   data is shown in red. One of the most exotic objects known to modern
   astronomers, [17]the Crab Pulsar, a neutron star spinning 30 times a
   second, is the bright spot near picture center. Like a cosmic dynamo,
   this collapsed remnant of the stellar core powers the Crab's emission
   across the electromagnetic spectrum. Spanning about 12 light-years, the
   Crab Nebula is 6,500 light-years away in the constellation [18]Taurus.
