Check out the full NASA video below, featuring simulated global “stuff in the air” over a two year period on Earth. Ain’t Earth beautiful? (Even if, as in this case, it’s a 3 million processor-hour computer animation)

In 1967, Kathrine Switzer was the first woman to enter and complete the Boston Marathon as a numbered entry. She registered under the gender-neutral name of “K.V. Switzer”. After realizing that a woman was running, race organizer Jock Semple went after Switzer shouting, “Get the hell out of my race and give me those numbers.” however, Switzer’s boyfriend and other male runners provided a protective shield during the entire Marathon. These photographs taken of the incident made world headlines.
