Solar eclipses, supermoons, a star-studded night sky — for us earthlings, looking up into space can be a transformative experience.

But what about the other way around? What is it like to see the entire earth from space? Only a select group of astronauts have had that grand opportunity.

"There was actually a physical moment in time when we answered a puzzle — something that's puzzled us throughout the whole of human history: What did the Earth look like from the outside?" says science historian Christopher Potter.

In the summer of 1967, Linda Walker was at Girl Scout camp in North Carolina when a lightning bolt struck her.

She says she was in a tent with three other girls when they all ran out after the crackle and boom. Walker was on the floor, unresponsive.

"But as Girl Scouts you always keep up with your buddy — you never lose track of your buddy," Walker says. "And my buddy walked out, ran out of the tent without me, but realized I wasn't with her and came back. Had she not done that, I wouldn't be here today ... because she saved my life."

This past week, a FedEx employee from Germantown, Tenn., made a massive discovery — and it wasn't in any packages. John Pace found the largest prime number known to humankind.

And that number goes on to more than 23 million digits.

Editor's note on Jan. 18: This story should have noted that artnet News was the first to report that the High Museum's proportion of nonwhite visitors has grown to 45 percent and now is close to the percentage of people of color who live in the Atlanta metropolitan area. That news site's report about the museum's "valuable case study" concerning how to diversify audiences is online here.

Just off a Houston freeway, in a strip mall with an Indian tailor and South Asian grocery store, is a small restaurant with an out-size reputation. It's called Himalaya and its chef and owner is a Houston institution.

Chef Kaiser Lashkari is a large man with a bushy salt-and-pepper mustache. He's constantly in motion — greeting clients, inspecting steaming dishes carried by busy waiters, calling out to his wife overseeing the kitchen. He offers us food before we've even sat down.
