H1 particle detector

H1 particle detector. Technician working on the H1 detector of the HERA accelerator at DESY (Deutsche Elektronen Synchrotron). HERA (Hadron Electron Accelerator Ring) consists of a pair of accelerator rings mounted in a 6.3km circumference tunnel. The H1 detector is placed at one crossing point of the rings. In the centre of the detector, protons from one ring will collide with electrons from the other ring at a combined energy of 850 GeV. It is hoped that data from this detector will provide more information about the quarks in protons and the gluon force moderators that bind them together.

Satellite image of Hurricane Nora over the Pacific

Hurricane Nora. Satellite image of Hurricane Nora off the coast of Baja California, Mexico. The hurricane is the swirl of clouds surrounding the dark hole (the "eye") at lower right. The "eye" is comprised of relatively calm, cloud-free air at a very low pressure. Around this "eye" are very strong winds which blow at over 100 kilometres per hour. Hurricanes form in tropical regions and are caused by large-scale evaporation and convection due to warm sea temperatures. The eastward movement of warm water in the Pacific (known an El Nino event) may cause more hurricanes to form off the American continent's coast.
