MONDAY PUZZLE — We are a society that tends to walk around with our eyes glued to our smartphones, but today’s puzzle is a wonderful reminder to “look up,” as my Facebook friend Aryan Mishra likes to say. Mr. Mishra, currently a 17-year-old student in Delhi, India, achieved prominence in 2014 when he and a fellow student discovered an asteroid in a competition and, if he continues in his chosen path as an aspiring astronaut, he might well eventually meet up with one of today’s crossword constructors.

That might sound like a weird segue, but please bear with me. I’m just back from vacation and am feeling a bit spacey myself. Today’s puzzle is another star-struck collaboration to help celebrate the 75th anniversary of The New York Times Crossword and here’s the connection: Our constructors today are Dr. Neil deGrasse Tyson, the astrophysicist and director of New York’s Rose Center for Earth and Space, which includes the Hayden Planetarium, and our queen of Monday puzzles, Andrea Carla Michaels. The Hayden Planetarium was one of my favorite places to visit when I was a child and Dr. Tyson and I are fellow graduates of the Bronx High School of Science, so it is my pleasure as a space geek to have him here, even if he did ruin thousands of childhoods by kicking Pluto out of the planet club. [She’s kidding. Dr. Tyson was not solely responsible for this. But it still hurts. — Ed.]

When you’re done with the puzzle and would like to daydream a bit about the cosmos, you could go outside and look up. Or, if it’s too cold where you are, you could set your computer monitor for full-screen and watch this amazing video of the Known Universe, courtesy of Dr. Tyson’s team at the American Museum of Natural History:
