Neil Ibata, a 15-year-old French high school student and the son of astrophysicist Rodrigo Ibata of the Strasbourg Observatory (Observatoire Astronomique de Strasbourg), poses next to a computer screen showing a 3D model representation of his research and the Andromeda galaxy at the observatory in Strasbourg Jan 5, 2013. Neil, working with his father, has participated in the discovery that many small companion dwarf galaxies surrounding Andromeda seem to orbit in concert, aligned in a vast, thin disk, which could change scientist's understanding of how galaxies form, according to media reports.
