Two Voyager 2 images of the planet Uranus

Voyager 2 images of Uranus taken on 17 January 1986, when the spacecraft was 9.1 million kilomet- res (5.7 million miles) from the planet. The left true-colour image was composed from a series taken with blue, green & orange filters. The darker shading corresponds to the day-night boundary. The blue-green colour results from absorption of red light by methane gas in Uranus's atmosphere. The right image uses false colour & contrast enhancement to bring out details in the polar region. A dark polar hood is visible surrounded by progressively lighter concentric bands. This might be due to a brown smog being arranged into bands by zonal motions of the upper atmosphere.

Rosebay pollination, SEM

Rosebay pollination. Coloured scanning electron micrograph (SEM) of the pistil (orange) and stamens (yellow) of a rosebay (Nerium oleander) flower. Numerous pollen grains (round) can be seen on the ripened, split, stamens (one seen from bottom left corner to centre left and lower centre). The stamen is the male reproductive organ and pollen grains contain the male gametes (sex cells) of a flowering plant. When they land on the pistil, the male gametes travel to the ovaries where they fertilise the female gamete (ovule). Rosebay is a poisonous evergreen shrub that is native to waterside habitats of the Mediterranean. Magnification: x100 at 6x7cm size
