Cabbage white caterpillar, SEM

Cabbage white caterpillar. Coloured scanning electron micrograph (SEM) of the caterpillar (larva) of a large (or cabbage) white butterfly (Pieris brassicae). Several dark ocelli (simple eyes) can be seen on the caterpillar's head (upper left). Some of its legs are seen at lower centre. This caterpillar is covered in hairs which make it unpalatable to predators. These caterpillars do huge amounts of damage to the cabbage crops in Europe, as they feed almost exclusively on these plants from birth until they pupate. Magnification: x19 at 5x7cm size.

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. NASA 5x4 photo number 86 HC 82
