At Kyoto University's Seto Marine Biological Laboratory on the Shirahama coast, biologist Shin Kubota has watched the same Turritopsis dohrnii jellyfish die and un-die so many times in his tank that he has started writing karaoke songs about an animal that, for all practical purposes, just refuses to stay dead.

In 2022, NASA engineers in Pasadena watched a new image come down from Perseverance and saw a small heap of broken rocks resting on the Martian surface in a pattern that looked almost intentional, and the explanation they eventually offered involved a vanished river that has not flowed in three billion years.

Perseverance landed in Jezero Crater on February 18, 2021, in a basin that scientists believe held a lake roughly 3.5 billion…
