报告摘要

The advent of the microscope in the 17th century ushered in radical perspective change in contemporary science with systems thought to be mundane and static, such as a droplet of water, found to be teeming with activity and life. A similar "resolution revolution" is now underway in the astronomical sciences with new technologies capable of delivering images of stellar systems at extremely fine angular scales. The results have been nothing short of breathtaking. Newborn planets have been revealed still circling within their embryonic disks. Elegant plumes and jets cast by dying stars have been imaged at unprecedented angular resolution. Several critical steps have been added to our understanding of the grand cycle of matter from primordial hydrogen processed through stellar nuclear furnaces, only to be recycled by stellar winds and star formation into subsequent generations of stars. Such discoveries are rapidly cementing the role of optical interferometers as today's microscopes for the stars.
