LCC-LFB Fireman in his fire kit with new cork helmet
A London fireman in his fire kit, including the new style compressed cork helmet with its LFB crest, which replaced the traditional brass helmets used since the days of the Metropolitan Fire Brigade. The change was necessary because of the risk of electrocution with the brass helmet and the greater strength, protection and lightness offered by the new helmet.

Europe at night, 1993-2003 changes
Europe at night, showing the change in illumination from 1993-2003. This data is based on satellite observations. Lights are colour-coded. Red lights appeared during that period. Orange and yellow areas are regions of high and low intensity lighting respectively that increased in brightness over the ten years. Grey areas are unchanged. Pale blue and dark blue areas are of low and high intensity lighting that decreased in brightness. Very dark blue areas were present in 1993 and had disappeared by 2003. Much of western and central Europe has brightened considerably. Some North Sea gas fields closed in the period.

Earth and Moon with dwarf planets
Earth and Moon with dwarf planets. Scaled computer artwork of (from left) Earth, the Moon, Pluto and Ceres. The latter are two of the solar system's dwarf planets. Pluto, which used to be a planet, was demoted in August 2006 to the status of dwarf planet, reducing the solar system's number of planets to eight. The definition of a dwarf planet is an object large enough to be spherical due to gravity, and with an independent orbit. A true planet, such as the Earth, has to dominate its orbit around the Sun. Pluto fails because it is one of many Kuiper Belt objects in the outer solar system. Ceres fails because it is one of many objects in the asteroid belt. The Moon fails because it is a satellite of the Earth.
