Engadget --------- NASA's Voyager 2 probe may be close to joining its sibling and entering interstellar space. The vessel has been detecting a five percent increase in cosmic rays since late August, suggesting that it's close to crossing the heliopause (the edge of the solar wind bubble, aka the heliosphere) and entering the interstellar realm. Voyager 1 saw similar increases in May 2012, so its fellow spacecraft may be in for a repeat. To learn more click on the picture below to read the article.
