“Messina Chasmata”的意思、由来-开放百科全书

The Messina Chasmata are the largest canyon or system of canyons on the surface of the Uranian moon Titania, named after a location in William Shakespeare's comedy Much Ado About Nothing.^[1] The 1492 km long feature includes two normal faults running NW–SE, which bound a down-dropped crustal block forming a structure called a graben.^[2] The graben cuts impact craters, which probably means that it was formed at a relatively late stage of the moon's evolution,^[3] when the interior of Titania expanded and its ice crust cracked as a result. The Messina Chasmata have only a few superimposed craters, which also implies being relatively young. The feature was first imaged by Voyager 2 in January 1986.^[2]
