Has the Voyager spacecraft left the solar system and entered interstellar space? I don’t know about you, but I’m getting a teensy weensy bit bored by this question, which has been going on for years now.

Last September, we blogged about a paper in Science that, yep, it had definitely left the solar system a year before – on 25 August 2012 in fact.

Previous to that, though, there had been other reports that no it hadn’t (June 2013), it really, definitely is getting near the edge, but hang on actually not yet (March 2013), we’re not quite sure (June 2011), of course it’s definitely heading for interstellar space (November 2009), it’s already right near the edge (or possibly not) (November 2003).

Yesterday a paper appeared in Science that makes the case that the Voyager 1 spacecraft has left the solar system. The response from the press and commenters has been to declare this a day to remember. Indeed, some have likened it to 20 July 1969 when Neil Armstrong first stepped on the Moon.
