EponymWilliam Herschel & John Herschel

Herschel is an impact crater[1] in Mars's southern hemisphere. At roughly 304 kilometers in diameter, it is a moderately large impact crater. Located at 14.5°S, 130°E, Herschel is in the Mare Tyrrhenum region[2] of Mars. The crater is jointly named after the seventeenth/eighteenth century father and son astronomers William Herschel and John Herschel.[3]

Dark dunes in Hershel crater.

Moving Sand Dunes

Mars Global Surveyor spacecraft originally photographed fields of dark sand dunes within Herschel.[4][5] Images from the NASA Mars Reconnaissance Orbiter showed that sand dunes on the floor of the Herschel crater are not stationary (as previously believed), but moved over time. Images from photos taken by the Orbiter's High Resolution Imaging Science Experiment (HiRISE) on March 3, 2007 and December 1, 2010 show clear shifting of dunes and ripples.[6] Research published in Icarus stated that the dunes in Hershel Crater moved 0.8 m in a time span of 3.7 Earth-years. Also, it was determined that dune ripple moved 1.1 m in that time period.[7]

Character pairing in The Lord of the Rings

Psychological pairing of characters in The Lord of the Rings Character pairing in The Lord of the Rings is a literary device used by J. R. R. Tolkien, a Roman Catholic, to express some of the moral complexity of his major characters in his heroic romance, The Lord of the Rings. Commentators have noted that the format of a fantasy does not lend itself to subtlety of characterisation, but that pairing allows inner tensions to be expressed as linked opposites, including, in a psychoanalytic inte...
