  • Image Caption: Artist’s impression of the graphenes (C24) and fullerenes found in a Planetary Nebula. The detection of graphenes and fullerenes around old stars as common as our Sun suggests that these molecules and other allotropic forms of carbon such a
    Nobel-prize winning scientists (2010), Andre Geim and Konstantin Novoselov, synthesized graphene in the laboratory in 2004. Just seven years later, this material of extraordinary strength, thinness and elasticity may have been found in space. The first evidence of the possible existence of C 24 - a flat two-dimensional molecule, one atom thick, possibly a "small piece of graphene - in space has been found. To confirm beyond a doubt that what has been detected is actually C 24, laboratory spectroscopy would have to be carried out, something which is practically impossible with current

  • Artistic composition of the fullerenes and polycyclic aromatic hydrocarbons found in a R Corona Borealis star rich in hydrogen. The non-detection of these molecules in the vast majority of very hydrogen-poor R Coronae Borealis stars contradicts the terres
    The largest known molecules in space, fullerenes, do not occur in hydrogen-poor environments as previously thought. Fullerenes are very stable molecules and difficult to destroy, they have a structure very similiar to that of a soccer ball and made of 60 carbon atoms arranged in three-dimensional spherical structures and patterns of alternative hexagons and pentagons. These molecules were synthesized in the laboratory by chemists Harold Kroto and Richard Smalley, who thus received the 1996 Nobel Prize in Chemistry. Kroto and Smalley, according to the laboratory experiments, believed that

  • Left: time evolution of a weak circular polarization patch. The black and white background represents the magnetic flux density computed in the weak field approximation, saturated to +- 20 Mx cm-2. Blue lines represent iso-magnetic flux densities of -130,
    As we enhance the spatial resolution and sensitivity of spectro-polarimetric measurements, it becomes increasingly evident that highly dynamic magnetic fields permeate the whole quiet Sun. These weak magnetic flux concentrations emerge somewhat preferentially in granules, where plasma motions are more favorable for the magnetic fields to rise across the solar atmosphere. Surprisingly (due to their weak nature), organized structures in the form of Omega-shaped loops survive convective motions and reach higher layers, at least the lower chromosphere (Martínez González & Bellot Rubio 2009
