Where were you for the 2017 total eclipse? Where will you be this year? And where will you be for the next one in 2045? Hanna talks to Atlantic staff writer Marina Koren about the eclipse as a peculiar event: a beautiful if not slightly unsettling moment that is also a strange marker of time.

And we hear from retired astrophysicist Fred Espenak who's seen more than 20 total eclipses in his life and wonders which eclipse might end up being his last.
