DESCRIPTION:Recently\, PH3 was observed in the clouds of Venus
 . I will provide a brief summary of the detection 
 and analysis. I will then talk about how destructi
 ve photochemistry of PH3 constrains its lifetime\,
  and provides one test that any proposed mechanism
  must pass in order to explain the observed concen
 trations of PH3 in the atmosphere. I will discuss 
 potential mechanisms to produce PH3 on Venus\, and
  will show that they are insufficient to explain t
 he observations. I will briefly discuss the possib
 ility of and challenges faced by microbial life in
  the clouds of Venus\, and the broad implications 
 of future research\, whether or not life is presen
 t in the clouds of Venus.
