I just learned this about Voyager 2, and being that Ben Davidson is about to start the Cosmology series it kind of fits this topic.



I and others have done stories on Voyagers 1&2 the importance of the data sent back from both Voyager craft, will I believe be the first warning of a galactic Super wave that may trigger a micro nova.



These are smilies I made last year from live Voyager data streams that you can monitor here.
