The astronauts aboard the International Space Station work every day on all kinds of experiments, from working with robots to preparing for spacewalks. But when they get a break, they often field questions from school children and adults about life in space.[...]
Like many positive terms, the phrase “big bang” originated as a pejorative. Fred Hoyle coined the term in 1949 as a way of deflating the concept of an expanding universe.

Preppers, it’s almost the big day you’ve been waiting for — the apocalypse and armageddon all rolled into one. Almost, but not quite. According to NASA, “an asteroid about half the size of a football field will fly past Earth only 17,200 miles above our planet’s surface.[...]
