Abstract:

The data on the far-ultraviolet extinction of starlight in our galaxy and in external galaxies is interpreted in terms of the widespread occurrence of organic particles of optical refractive index 1.4 and radii less than or equal to 20~nm. Such particles are candidates for nanobacteria such as recently been found in abundance on the Earth.
