It's known as "first light," and, broadly speaking, it's the first snapshot taken by an instrument. However, in this case, this first snapshot is historic, because it's the first light taken by the world's largest digital camera. This Monday, the first images from the Rubin Observatory, located in Chile, were made public. Its mission is to create the most complete film of the night sky ever made. The Legacy Survey of Space and Time (LSST) is the mapping project that will scan the southern sky over the next 10 years. The project is an international collaboration funded by the U.S. National Science Foundation (NSF) and the U.S. Department of Energy (DOE), with the participation of two centers of the Spanish National Research Council (CSIC).
