    The Phosphine Discovery, in Context of Venus's More Temperate Past

    At this month's Science Cafe, we'll talk about the recent discovery of the chemical phosphine in an upper layer of Venus's atmosphere and why this is more exciting than it sounds! On Earth, phosphine is only created by biological and human-driven processes. Is the detection of phosphine in Venus's atmosphere a sure sign of life living in the clouds? We'll start with the history of Venus and its runaway greenhouse effect. Today, Venus seems very inhospitable to life, with surface temperatures above 800°F and sulfuric acid clouds. But it wasn't always like that, which is why we are even discussing the possibility of life on Venus.

    There will also be a live stream from our own Kennon Observatory showing us craters on the Moon, if the weather cooperates.
