Discovery of Jupiter's 'gossamer' ring.

abstract：:Collagen fibrils have been extensively studied by electron microscopy, but only scant evidence has yet been obtained about their transverse structure. A transverse pediodicity of about 40 or 80 A might be expected if the microfibril model (until recently the common preference) is correct, but little direct evidence fo...
