| Abstract | ||
| Microbial Model, an ancient idea, posits that microbial life is ubiquitous in the Universe. After several decades of almost irrational rejection, Astronomical data is shown to be consistent with the widespread distribution of complex organic molecules and dust particles that may have a biological provenance. A minuscule (10-21) survival rate of freeze-dried bacteria in space is all that is needed to ensure the continual re-cycling of cosmic microbial life in the galaxy. The aim of this work is to study the nature of interstellar matter throughout Milky Way Galaxy via comparison of stellar spectrum of reddened and un reddened stars of some spectral classes the galactic plane . Observations of six regions in the Milky Way Galaxy were adopted via (IUE) data satellites .These observations are made through wavelength (0.4 – 8.4)µm1.Extinction curve was compared with the microbial model ,the results show good agreement with this curve ,which explains the interstellar matter as a mixture of organic and inorganic particle of different size. | ||
