NASA’s Wide-field Infrared Survey Explorer has helped researchers get a better look at the Phoebe ring’s enormity since it can only be seen as a faint halo at infrared wavelengths.

Graphene is a material with outstanding electronic characteristics. Many of them arise from the cone-like dispersion of charge carriers near the Fermi level (at which the occupation probability of energy levels is 0.5), where electrons behave as relativistic Dirac fermions, i.e., as if they had no mass. This excellent video from toutestquantique.fr summarizes them very […]

A extremely rare set of 4 quasars Astronomers have spotted an extremely rare grouping of four quasars within about 650,000 light-years of space. The odds against finding four so close together are 10 million to one. The rare quartet exists in an unusually bright nebula that has scientists scratching their heads as well. National Geographic […]
