And the question arose...........

........................................................"How much should we know?"  And the answer gently wafted by, " Not so much."

Explanation: Beautiful spiral galaxy NGC 6744 is nearly 175,000 light-years across, larger than our own Milky Way. It lies some 30 million light-years distant in the southern constellation Pavo and appears as only a faint, extended object in small telescopes. We see the disk of the nearby island universe tilted towards our line of sight in this remarkably detailed galaxy portrait, a telescopic view that spans an area about the angular size of a full moon. In it, the giant galaxy's elongated yellowish core is dominated by the light from old, cool stars. Beyond the core, grand spiral arms are filled with young blue star clusters and speckled with pinkish star forming regions. An extended arm sweeps past a smaller satellite galaxy (NGC 6744A) at the lower right. NGC 6744's galactic companion is reminiscent of the Milky Way's satellite galaxy the Large Magellanic Cloud.

      "The simplicity of the universe is very different from the simplicity of a machine.  He who sees moral nature out and out, and thoroughly knows how knowledge is acquired and character formed is a pedant.  The simplicity of nature is not that which may easily be read, but is inexhaustible.  The last analysis can no wise be made.  We judge of a man's wisdom by his hope, knowing that the perception of the inexhaustibleness of nature is an immortal youth.  The wild fertility of nature is felt in comparing our rigid names and reputations with our fluid consciousness."

-Ralph Waldo Emerson, from his 1841 Spiritual Laws essay
