A young woman poses with her home-made eclipse viewers on the steps outside of MIT's Building 7 on Massachusetts Avenue on the campus of MIT after a solar eclipse viewing event in Cambridge, Massachusetts, USA, on Mon., Aug. 21, 2017. This solar eclipse is the first in nearly 40 years to have a path observable total eclipse from coast to coast in the United States. People at this location in Massachusetts, however, only observed about 66% coverage of the moon over the sun.
