An international team of astronomers, led by a University of Arizona graduate student, has discovered the most distantly orbiting planet found to date around a single, sun-like star. Weighing in at 11 times Jupiter’s mass and orbiting its star at 650 times the average Earth-Sun distance, planet HD 106906 b is unlike anything in our own Solar System and defies current planet formation theories.

Pinning Down Aerosols to Shed Light on Visibility, Clouds, Climate Change

UANews | December 3, 2013
UA researcher Armin Sorooshian and his research team recently conducted two aircraft field studies to investigate haze, dust and smoke – those little-understood ubiquitous aerosol particles. In studying the properties of such particles in the atmosphere, the team is working to help scientists to better understand aerosol-cloud interactions and predict climate change.
