This is Ephemeris for Thursday, September 24th. Today the Sun will be up for 12 hours and 2 minutes, setting at 7:35, and it will rise tomorrow at 7:34. The Moon, 1 day past first quarter, will set at 12:49 tomorrow morning.
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.
The event times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.
