View of our Milky Way galaxy

The Milky Way. Map of the central region of our galaxy, seen from a tilted angle. The Milky Way is a spiral galaxy with a short bar (yellow-white) at centre and a diameter of about 100, 000 light years. It contains about 15 billion stars. Molec- ular clouds (orange) and bright nebulae (purple) populate the galaxy's spiral arms. Molecular clouds consist of molecules and dust, and are associated with regions of star formation. Nebulae are formed by hydrogen lit up and ionised by nearby young, hot stars. Clouds of neutral hydrogen are in yellow. Based on locations of 1500 stars, nebulae and other objects, the Henbest/Baum map of the galaxy was published in 1994

Coloured SEM of dentine with protoplasmic fibres

Dentine. Coloured scanning electron micrograph (SEM) of a section of healthy human dentine, a dense calcified tissue which forms the bulk of the body of a tooth. Dentine is similar to bone in composition, but is more highly mineralised & consequently much harder than bone. Dentine forms when the organic matrix secreted by cells called odontoblasts becomes calcified. It occurs between the enamel and the inner dental pulp and is permeated by a network of minute channels. These channels contain protoplasmic processes (coloured pink) of the odontoblasts. Dentine is highly sensitive to both touch & extremes of temperature. Magnification: x1, 100 at 6x7cm size. x2, 960 at 8x6ins, x1570 at 10x7cm master size
