Scientists believe that below the visible cloud tops of ammonia reside layers of ammonium hydrosulfide and water vapor, but they found only wisps of gases and some evidence of water droplets.
What was encountered was a wispy layer of what appeared to be ammonia clouds, then a mist possibly of ammonium hydrosulfide, and finally a layer of particles that they said could be helium rain.
