Reanalyzing old data with our modern understanding seems to be in vogue lately. However, the implications of that reanalysis for some topics are more impactful than others. One of the most hotly debated topics of late in the astrobiological community has been whether or not life can exist on Venus - specifically in its cloud layers, some of which have some of the most Earth-like conditions anywhere in the solar system, at least in terms of pressure and temperature. A new paper from a team of American researchers have just added fuel to that debate by reanalyzing data from the Pioneer mission to Venus NASA launched in the 70s - and finding that the Venus clouds are primarily made out of water.
