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: Why does the Sun's surface keep changing? The help find
   out, the US [7]National Science Foundation (NSF) has [8]built the
   [9]Daniel K. Ino[10]uye Solar Telescope in [11]Hawaii, [12]USA. The
   [13]Inouye telescope has a larger mirror that enables the capturing of
   images of higher resolution, at a faster rate, and in more colors than
   ever before. Featured are recently-released [14]first-light images
   taken over 10 minutes and combined into a 5-second time-lapse video.
   [15]The video captures an area on the Sun roughly the size of our
   Earth, features [16]granules roughly the size of a country, and
   resolves features as small as 30-kilometers across. Granule centers are
   bright due to the upwelling hot [17]solar [18]plasma, while granule
   edges are dim due to the cooled plasma falling back. Some regions
   between granules edges are [19]very bright as they are [20]curious
   magnetic windows into a deep and hotter solar interior. How the Sun's
   magnetic field [21]keeps changing, channeling energy, and affecting the
   distant Earth, among [22]many other topics, will be studied for years
   to come using data from the new [23]Inouye telescope.
