UA Astronomers Discover Planet That Shouldn't Be There

Mon, 2014-02-03 00:02
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.

Growing Hydroponic Strawberries in the Desert

Mon, 2014-02-03 00:02
Chieri Kubota came to the UA from Japan with many goals, including growing strawberries hydroponically in the desert Southwest. Her focus is flavor over shelf life. Her goal is to test varieties and high-tech growing methods – then work with greenhouse growers to cultivate strawberries in the winter for local farmers markets, grocers and restaurants. Little did she know that in the 1890s Arizona was famous for its luscious off-season strawberry crop.
