Topographic map of Venusian north polar region Featured May Print

Topographic map of Venusian north polar region

Colour-coded topographic map of the region surrounding Venus north pole. The view is centred on the pole and extends down to a latitude of 20 degrees north. Yellow areas represent high ground & orange areas low ground. The yellow region just below centre is Ishtar Terra and contains Lakshmi Planum (smooth area at left) and the Maxwell Montes (rough terrain at right), the highest mountains on Venus. The rope-like ridges at upper left are thought to be tectonic in origin. The map was compiled using data from the Soviet Venera 15 & 16 spacecraft, the American Pioneer Venus spacecraft and the Arecibo radio telescope in Puerto Rico

False-colour SEM of the crown wheel of a watch Featured May Print

False-colour SEM of the crown wheel of a watch

False-colour scanning electron micrograph of the crown wheel of a Swiss-made, 17-jewel INCABLOC watch. The crown wheel is part of the watch's winding mechanism. When the watch is wound, the winding pinion (small gear wheel seen edge-on at bottom) rotates, meshing with the crown wheel. The rotation of the crown wheel causes the ratchet wheel at top left to turn, & this wheel is attached to the barrel which holds the mainspring of the watch. The mechanism is clean; the tiny dust particles would not affect its function. The absence of screwdriver marks in the crown wheel's slot shows that the assembly has never been serviced. Magnification: x4 at 6x4.5cm size
