re: Arecibo Message sent to Messier 13 thirty years ago
It means the message has passed Vega! (Well, not exactly in the same direction....) What's also interesting is the solar system is traveling towards a point between M13 and Vega. But one day, it will head back to the south.
It would be a lot easier for the readers if the links were accessible using HTML, wouldn't it!
Here's the way to do it and once it's known, it's fun to use!
