Early haze likely shaded Earth from UV
U. COLORADO (US)—A thick organic haze that enshrouded early Earth several billion years ago may have been similar to the haze now hovering above Saturn’s largest moon, Titan, and would have protected primordial life on the planet from the damaging effects of ultraviolet radiation. (more…)

Model suggests it’s raining rocks on exoplanet
WASHINGTON-ST. LOUIS (US)—An exoplanet discovered last February by the COROT space telescope is close enough to its star that its “day-face” is hot enough to melt rock. Theoretical models suggest the planet has a gaseous-rock atmosphere and boiling oceans on its surface. (more…)

Dancing with high-temp superconductors
A computer-generated representation of the data obtained by scanning a cuprate superconductor in sub-atomic steps. Each cross represents a “Cooper pair” of electrons. At a temperature below 37K (bottom sheet) the pairs are in an orderly arrangement and current can flow without resistance. At a higher temperature the Cooper pairs are still present, but no longer orderly. (Credit: Jhinhwan Lee/Davis Group/Cornell University)
