Three years ago astronomers began to discover phosphine in the atmosphere of Venus. The chemical phosphine is related to ammonia in that it has three hydrogen atoms. They are tied to phosphorus rather than to nitrogen as is ammonia. It can also be created biologically, as it is almost entirely created on the Earth. It also is produced by volcanoes, and Venus has evidence of volcanic action. After three years of observation and looking for and ruling out non biological origins of phosphine they made public the announcement last week Monday. The detection was made in the millimeter wavelengths of the electromagnetic spectrum between microwave and the infrared. Is life responsible? A space probe or many to Venus will be needed to find out to help solve the mystery.
