HUBBLE'S LARGEST GALAXY PORTRAIT OFFERS A NEW HIGH-DEFINITION VIEW

Giant galaxies weren't assembled in a day. Neither was this Hubble
Space
Telescope image of the face-on spiral galaxy Messier 101 (M101). It is
the largest and most detailed photo of a spiral galaxy that has ever
been released from Hubble. The galaxy's portrait is actually composed
of
51 individual exposures taken with Hubble's Advanced Camera for Surveys
and the Wide Field and planetary Camera 2 in March 1994, September
1994,
June 1999, November 2002, and January 2003. The newly composed image
also includes elements from images from ground-based photos. The final
composite image measures a whopping 16,000 by 12,000 pixels.
