114 years ago, this super-rare microorganism was discovered — only four people have seen it since

You are more likely to take a trip to the Moon than to see a microbe called Legendrea loyezae under a microscope. Nasa’s Apollo program sent a total of 24 people to the Moon between 1968 and 1972. Only four people (including us) have ever found Legendrea loyezae from its discovery in 1908 to our recently published study.
