"It is always difficult to establish if the eclipses were seen in the ancient past as bad omens or good omens."

About two weeks after the blood moon comes a partial solar eclipse visible in the early morning, giving the sun a crescent shape.

Saturday's partial solar eclipse offers the rare chance to see a "double sunrise" in the northeastern part of the country. Why it matters: It's the only solar eclipse visible from the U.S. this year and comes two weeks after the total lunar eclipse.
