Watering hole: An illustration released Monday by NASA shows the possible size what was once an ancient lake inside Mars’ Gale Crater. Analyzing sedimentary rock, NASA’s Curiosity rover found evidence of the ancient lake . The possible extent was estimated by mapping stream deposits and recognizing that water flowed from the crater rim into the basin (arrows). The water would have pooled in the linear depression created between the crater rim and Mount Sharp.
The late Victorians and the Edwardians lived through a domestic revolution.

Mike the Hog-a-Nator remembers thinking: What the world? Then he went inside for his weekly appointment.
