AxS ("axis") is a 2-week city-wide festival produced by the Pasadena Arts Council, exploring the nexus of artistic and scientific inquiry and promoting cross-fertilization between these disciplines.  The theme of the 2014 Festival is "Curiosity" - the interplay between human curiosity, scientific investigation and artistic endeavor that also illuminates the diversity and innovation of human achievement in the 21st century.

Pasadena, CA—Something is amiss in the Universe. There appears to be an enormous deficit of ultraviolet light in the cosmic budget.

The vast reaches of empty space between galaxies are bridged by tendrils of hydrogen and helium, which can be used as a precise “light meter.” In a recent study published in The Astrophysical Journal Letters, a team of scientists finds that the light from known populations of galaxies and quasars is not nearly enough to explain observations of intergalactic hydrogen. The difference is a stunning 400 percent.
