Acanthamoeba is a microscopic, free-living amoeba, or amoeba (single-celled living organism), that can cause rare but serious eye, skin, and central nervous system infections. The amoeba is found worldwide in the environment in water and soil. The amoeba can spread to the eyes through the use of contact lenses, cuts or wounds in the skin, or by being inhaled into the lungs. Most people will be exposed to Acanthamoeba in their lifetime, but very few will become ill from this exposure.

Scanning electron microscopic image of Streptococcus bacteria

Range 12.9 million miles (8.0 million miles) P-29468C This false color Voyager photograph of Uranus shows a discrete cloud seen as a bright streak near the planets limb. The cloud visible here is the most prominent feature seen in a series of Voyager images designed to track atmospheric motions. The occasional donut shaped features, including one at the bottom, are shadows cast by dust on the camera optics. The picture is a highly processed composite of three images. The processing necessary to bring out the faint features on the planet also brings out these camera blemishes. The three seperate images used where shot through violet, blue, and orange filters. Each color image showd the cloud to a different degree; because they were not exposed at the same time , the images were processed to provide a good spatial match. In a true color image, the cloud would be barely discernable; the false color helps to bring out additional details. The different colors imply variations in vertical st
