Title:
The Big Corona
Explanation:
Most photographs don't adequately portray the magnificence of the Sun [ http://www.nineplan…]'s corona. Seeing the corona [ http://www.lmsal.co…] first-hand during a total solar eclipse [ http://www.mreclips…] is best. The human eye [ http://www.orlions.…] can adapt to see features and extent that photographic film [ http://web.islandne…] usually cannot. Welcome, however, to the digital [ http://gcc.bradley.…] age. The above picture [ http://www.mreclips…] is a combination of twenty-two photographs that were digitally processed to highlight faint features of a total eclipe that occurred in August of 1999. The outer pictures of the Sun's corona [ http://www.windows.…] were digitally altered to enhance dim, outlying waves and filaments. The inner pictures of the usually dark Moon [ http://antwrp.gsfc.…] were enhanced to bring out its faint glow from doubly reflected sunlight [ http://antwrp.gsfc.…]. Shadow seekers [ http://sunearth.gsf…] need not fret, though, since as yet there is no way that digital image processing can mimic the fun [ http://antwrp.gsfc.…] involved in experiencing a total solar eclipse [ http://www.mreclips…]. The next total solar eclipse [ http://sunearth.gsf…] will be visible from parts of Africa on June 21.
