Sorry, it's a scientific paper, no web page link that I can find as of now...
We report the discovery for the first time of diatom frustules in a carbonaceous meteorite that fell in the North Central Province of Sri Lanka on 29 December 2012. Contamination is excluded by the circumstance that the elemental abundances within the structures match closely with those of the surrounding matrix. There is also evidence of structures morphologically similar to red rain cells that may have contributed to the episode of red rain that followed within days of the meteorite fall. The new data on “fossil” diatoms provide strong evidence to support the theory of cometary panspermia.
In the higher resolution image of Fig3 we can unambiguously identify an object as being a diatom from its complex and highly ordered microstructure and morphology, a structure that cannot result from any conceivable mineralisation or crystallisation process. The mineralised fossil structure of the original diatom has been preserved intact and displays close similarities in elemental abundances with the surrounding material. This is shown in the EDX maps in Fig.4, that compares the distribution of elements inside and outside the fossilised object.
Comparison of the SEM images of another fossil diatom in the Polonnaruwa meteorite with a modern diatom Sellaphora blackfordensis (Mann, 1989,1999) is shown in Fig 7 and leaves scarcely any room to doubt the identity of the former. Again we stress that contamination is decisively ruled out because the structure in the meteorite is deemed to be a fossilised object, and fossils diatoms were not present near the surface of the Earth to contaminate a new fall of meteorites.
So basically... diatoms (algae-like cells) were found in a meteorite that fell last december. Scientists ruled out contamination and ruled out that what is in the images were produced by any non-biological method. Cells on a meteor = life outside of earth = ALIENS!
