International Journal of Astrobiology, 2003 If the discoveries of C60 and C70 fullerenes in terrestrial hard rocks are real, then some of these may have formed in the solid state by dehydrogenation-driven ‘zip-up’ of C60Hn and C70Hm progenitors. At three sites of such fullerene discoveries the building blocks for these large molecules may have come from algal remains.

On the Excitation and Formation of Circumstellar Fullerenes [PDF]
, 2012 We compare and analyze the Spitzer mid-infrared spectrum of three fullerene-rich planetary nebulae in the Milky Way and the Magellanic Clouds; Tc1, SMP SMC16, and SMP LMC56. The three planetary nebulae share many spectroscopic similarities. The strongest

A search for diffuse bands in fullerene planetary nebulae: evidence of diffuse circumstellar bands
, 2014 Large fullerenes and fullerene-based molecules have been proposed as carriers of diffuse interstellar bands (DIBs). The recent detection of the most common fullerenes (C60 and C70) around some planetary nebulae (PNe) now enable us to study the DIBs ...
