1. 5月14日学术报告：Dawn at Vesta: A Whole New World 时间：5月14日上午10:00 报告人：Dr. Jian-Yang Li 单位：Department of Astronomy, University of Maryland 地点：东区 行政科研楼706 摘要：    Asteroids, as both the building blocks of and leftovers from the formation of our planetary system, retain important information about the processes of planet formation. Vesta is one of the largest asteroids, representing the early stage of terrestrial planet formation and the transition from planetesimals to a full-sized planet. Dawn spacecraft currently in orbit around Vesta returned a huge amount of multispectral imaging and spectroscopic data in the visible and near-infrared wavelengths at a scale as high as 20 m/pix, converting Vesta from an astronomical object to a whole new world of geology and mineralogy. Vesta's geology is mostly controlled by its complicated impact history since its formation.  The heterogeneous surface of Vesta in its albedos, colors, and spectra suggest an extremely diverse mineralogy. Vesta, as seen by Dawn, is a unique world full of surprises in many aspects. 欢迎感兴趣的空间物理、地球物理、地球化学、天文学老师和同学参加。
