People gather to observe the solar eclipse in the Kresge Oval and outside the Stratton Student Center at MIT 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. MIT set up telescopes to safely observe the eclipse, in addition to homemade camera obscura and pinhole viewers and eclipse glasses.
