A total solar eclipse will sweep across the United States on Monday, treating 13 states from Texas to Maine to a stunning celestial show.
During the eclipse, the moon will cast its shadow on parts of North America as it comes between Earth and the sun, said Gina DiBraccio, the deputy director of heliophysics at NASA's Goddard Space Flight Center.
But the solar eclipse will be visible far outside the path of totality. Pittsburgh would see about 90% of the sun obscured. Washington, D.C., is set to see about 85% coverage.

As the paths of the sun and moon overlap, the sky will grow darker, winds may change, and temperatures are expected to slightly drop.

The next total solar eclipse to sweep across the continental United States is set to occur on August 12, 2045, following a path from northern California to Florida, according to NASA (although Alaska will see one in 2033, and a total eclipse will pop over Montana and North Dakota in 2044, Forbes reports).
