Is there a problem with the AstronomicalData link with Wolfram database ? Try this: AstronomicalData["AndromedaGalaxy","DistanceLightYears"] , as listed in the Help documentation. I get a dash for answer, but the Help documentation gives an answer before evaluating. When I try to get something from evaluating from the Help documentation I get the dash for answer. Also, I think that Pluto is not a planet anymore! But it is still listed as one. So, where does the database come from? Same question for the other databases that we get data from! How can I be sure that the data is accurate! Robert
