Primary mirror of the Hobby-Eberly Telescope

Hobby-Eberly telescope. Astronomer with the primary mirror of the Hobby-Eberly Telescope (HET). Commissioned in late 1997, the HET has the world's largest primary mirror. The 11-metre mirror consists of 91 identical 1-metre hexagonal segments. The use of a segmented mirror greatly reduces construction costs. Unlike most telescopes, the HET tracks objects across the sky not by rotating the entire telescope but by moving just a few focusing instruments suspended above the primary mirror. This reduces by more than ten times the amount of mass that must be moved under precise control. Photographed at the McDonald Observatory in the Davis mountains of Texas, USA

Various pollen grains

Pollen grains. Computer-enhanced image of a Scanning Electron Micrograph (SEM) of several different types of pollen grain. The size, shape and surface texture of these pollen grains is unique in each plant species. The sculptured outer wall (or exine) of the grain plays a role in it's dispersal by wind, water or insects. Pollen grains contain the male gametes of the plant which fertilize the female egg (or ovule) to form the plant seed. Pollen also causes allergies and hay fever. Magnification: approximately x1000 at 4.5x6cm size
