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]Complex filaments of many colors cross the image in front of a
     starry background. Some regions have a diffuse red or orange glow.
          Please see the explanation for more detailed information.

   Explanation: The explosion is over, but the consequences continue.
   About eleven thousand years ago, a star in the constellation of
   [13]Vela could be seen to [14]explode, creating a strange point of
   light briefly visible to humans living near the beginning of
   [15]recorded history. The outer layers of the star crashed into the
   [16]interstellar medium, driving a [17]shock wave that is still visible
   today. The [18]featured image captures some of that filamentary and
   gigantic shock in [19]visible light. As gas flies away from the
   detonated star, it [20]decays and reacts with the interstellar medium,
   producing light in many different colors and energy bands. Remaining at
   the center of the [21]Vela Supernova Remnant is a [22]pulsar, a star as
   dense as nuclear matter that [23]spins around more than ten times in a
   single second.
