This high-resolution scanning electron microscope image shows an unusual 
tube-like structural form that is less than 1/100th the width of a human hair 
in size found in meteorite ALH84001, a meteorite believed  to be of Martian 
origin. Although this structure is not part of the research published in the 
Aug. 16 issue of the journal Science, it is located in a similar carbonate 
glob in the meteorite. This structure will be the subject of future 
investigations that could confirm whether or not it is fossil evidence of 
primitive life on Mars 3.6 billion years ago.
